Spring Boot - How to log all requests and responses with exceptions in single place?

I'm working on rest api with spring boot. I need to log all requests with input params (with methods, eg. GET, POST, etc), request path, query string, corresponding class method of this request, also response of this action, both success and errors. For example:

successful request:

http://example.com/api/users/1

Log should look something like this:

{
   HttpStatus: 200,
   path: "api/users/1",
   method: "GET",
   clientIp: "0.0.0.0",
   accessToken: "XHGu6as5dajshdgau6i6asdjhgjhg",
   method: "UsersController.getUser",
   arguments: {
     id: 1 
   },
   response: {
      user: {
        id: 1,
        username: "user123",
        email: "user123@example.com"   
      }
   },
   exceptions: []       
}

Or request with error:

http://example.com/api/users/9999

Log should be something like this:

{
   HttpStatus: 404,
   errorCode: 101,                 
   path: "api/users/9999",
   method: "GET",
   clientIp: "0.0.0.0",
   accessToken: "XHGu6as5dajshdgau6i6asdjhgjhg",
   method: "UsersController.getUser",
   arguments: {
     id: 9999 
   },
   returns: {            
   },
   exceptions: [
     {
       exception: "UserNotFoundException",
       message: "User with id 9999 not found",
       exceptionId: "adhaskldjaso98d7324kjh989",
       stacktrace: ...................    
   ]       
}

I want Request/Response to be a single entity, with custom information related to this entity, both in successful and error cases.

What is best practice in spring to achieve this, may be with filters? if yes, can you provide concrete example?

I've played with @ControllerAdvice and @ExceptionHandler, but as I mentioned, I need to handle all success and error requests in single place (and single log).

Probably via a logging ServletFilter (e.g. stackoverflow.com/a/2171633/995891 ), alternatively HandlerInterceptor but that may not work well with logging the response as mentioned in the answer: concretepage.com/spring/spring-mvc/… - HandlerInterceptor has access to the method (method: "UsersController.getUser") though. That's not known in a servlet filter.
still , even if you add a filter or whatever solution at application layer , you will not log all the request , f.e. the HTTP 500 Server Error will not get logged , cause at the time that an unhandled exception will get thrown at the Application layer , the default embedded tomcat's on error page will be displayed after swallowing the exception and ofcourse will not preserve the log. Also if you check user1817243 answer , in case of any exception he will again not log the request but he will log the exception (!!).
Does that log format must be consistent with every character you wrote? Seems like a JSON translation would be optimal in your case: LogClass{ getRequestAndSaveIt()} Gson.toJson(LogClass) as pseudocode
Future readers may benefit from my answer (url to follow in this comment). Basically, I was able to franken-stein together different posts about this question. PLEASE consider the actuator answer (in the answers below) before trying it by hand. But the answer I am posting allows "400, 404, 500" (any/all) to be logged, but setting the order-priority to the lowest-priority (or within by "8" if you look at the code). stackoverflow.com/questions/10210645/…
I did follow the spring docs on logging from here: docs.spring.io/spring-boot/docs/current/reference/html/…

Don't write any Interceptors, Filters, Components, Aspects, etc., this is a very common problem and has been solved many times over.

Spring Boot has a modules called Actuator, which provides HTTP request logging out of the box. There's an endpoint mapped to /trace (SB1.x) or /actuator/httptrace (SB2.0+) which will show you last 100 HTTP requests. You can customize it to log each request, or write to a DB.

To get the endpoints you want, you'll need the spring-boot-starter-actuator dependency, and also to "whitelist" the endpoints you're looking for, and possibly setup or disable security for it.

Also, where will this application run? Will you be using a PaaS? Hosting providers, Heroku for example, provide request logging as part of their service and you don't need to do any coding whatsoever then.


This cannot be used for debugging: unauthenticated requests (for example with spring security) do not get logged.
Actually Actuator doesn't have any specific components for enebling http logging. /trace - show only last N requests.
@ike_love, how to confgure actuator such that it logging request (also POST body) to file ?
Trace will not log request and response body for you....everything else (header etc) but those.
If you want the body, this is not useful, please mention it.

Spring already provides a filter that does this job. Add following bean to your config

@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
    CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
    loggingFilter.setIncludeClientInfo(true);
    loggingFilter.setIncludeQueryString(true);
    loggingFilter.setIncludePayload(true);
    loggingFilter.setMaxPayloadLength(64000);
    return loggingFilter;
}

Don't forget to change log level of org.springframework.web.filter.CommonsRequestLoggingFilter to DEBUG.


Note that it does not log the responses, only the requests.
There is only requests. How to log responses bodies using CommonsRequestLoggingFilter ?
Also this does not log Exception
Sorry newbie question but...add it to our config? in springboot for instance?
If you have large JSON body, set the payload length to a big number to log the whole request body. loggingFilter.setMaxPayloadLength(100000);

You could use javax.servlet.Filter if there wasn't a requirement to log java method that been executed.

But with this requirement you have to access information stored in handlerMapping of DispatcherServlet. That said, you can override DispatcherServlet to accomplish logging of request/response pair.

Below is an example of idea that can be further enhanced and adopted to your needs.

public class LoggableDispatcherServlet extends DispatcherServlet {

    private final Log logger = LogFactory.getLog(getClass());

    @Override
    protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {
        if (!(request instanceof ContentCachingRequestWrapper)) {
            request = new ContentCachingRequestWrapper(request);
        }
        if (!(response instanceof ContentCachingResponseWrapper)) {
            response = new ContentCachingResponseWrapper(response);
        }
        HandlerExecutionChain handler = getHandler(request);

        try {
            super.doDispatch(request, response);
        } finally {
            log(request, response, handler);
            updateResponse(response);
        }
    }

    private void log(HttpServletRequest requestToCache, HttpServletResponse responseToCache, HandlerExecutionChain handler) {
        LogMessage log = new LogMessage();
        log.setHttpStatus(responseToCache.getStatus());
        log.setHttpMethod(requestToCache.getMethod());
        log.setPath(requestToCache.getRequestURI());
        log.setClientIp(requestToCache.getRemoteAddr());
        log.setJavaMethod(handler.toString());
        log.setResponse(getResponsePayload(responseToCache));
        logger.info(log);
    }

    private String getResponsePayload(HttpServletResponse response) {
        ContentCachingResponseWrapper wrapper = WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        if (wrapper != null) {

            byte[] buf = wrapper.getContentAsByteArray();
            if (buf.length > 0) {
                int length = Math.min(buf.length, 5120);
                try {
                    return new String(buf, 0, length, wrapper.getCharacterEncoding());
                }
                catch (UnsupportedEncodingException ex) {
                    // NOOP
                }
            }
        }
        return "[unknown]";
    }

    private void updateResponse(HttpServletResponse response) throws IOException {
        ContentCachingResponseWrapper responseWrapper =
            WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        responseWrapper.copyBodyToResponse();
    }

}

HandlerExecutionChain - contains the information about request handler.

You then can register this dispatcher as following:

    @Bean
    public ServletRegistrationBean dispatcherRegistration() {
        return new ServletRegistrationBean(dispatcherServlet());
    }

    @Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
    public DispatcherServlet dispatcherServlet() {
        return new LoggableDispatcherServlet();
    }

And here's the sample of logs:

http http://localhost:8090/settings/test
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=500, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475814077,"status":500,"error":"Internal Server Error","exception":"java.lang.RuntimeException","message":"org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.RuntimeException","path":"/settings/test"}'}

http http://localhost:8090/settings/params
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=200, path='/settings/httpParams', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public x.y.z.DTO x.y.z.Controller.params()] and 3 interceptors', arguments=null, response='{}'}

http http://localhost:8090/123
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=404, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475840592,"status":404,"error":"Not Found","message":"Not Found","path":"/123"}'}

UPDATE

In case of errors Spring does automatic error handling. Therefore, BasicErrorController#error is shown as request handler. If you want to preserve original request handler, then you can override this behavior at spring-webmvc-4.2.5.RELEASE-sources.jar!/org/springframework/web/servlet/DispatcherServlet.java:971 before #processDispatchResult is called, to cache original handler.


what happens when the response is a stream and the stream doesn't support seek? Will the above still work?
I don't care about the method invoked, just the data received and sent. Filter appears to point me in the right direction and @ike_love's response has directed me to github.com/spring-projects/spring-boot/blob/master/…
@TomHoward AFAIK, there's no out of the box "response logging" in spring. Therefore you can extend WebRequestTraceFilter or AbstractRequestLoggingFilter adding response logging logic.
Works just fine!
@hahn why did you use Dispatcher servlet for this? can same login not be added with filter in doFilter?

The Logbook library is specifically made for logging HTTP requests and responses. It supports Spring Boot using a special starter library.

To enable logging in Spring Boot all you need to do is adding the library to your project's dependencies. For example assuming you are using Maven:

<dependency>
    <groupId>org.zalando</groupId>
    <artifactId>logbook-spring-boot-starter</artifactId>
    <version>1.5.0</version>
</dependency>

By default the logging output looks like this:

{
  "origin" : "local",
  "correlation" : "52e19498-890c-4f75-a06c-06ddcf20836e",
  "status" : 200,
  "headers" : {
    "X-Application-Context" : [
      "application:8088"
    ],
    "Content-Type" : [
      "application/json;charset=UTF-8"
    ],
    "Transfer-Encoding" : [
      "chunked"
    ],
    "Date" : [
      "Sun, 24 Dec 2017 13:10:45 GMT"
    ]
  },
  "body" : {
    "thekey" : "some_example"
  },
  "duration" : 105,
  "protocol" : "HTTP/1.1",
  "type" : "response"
}

It does however not output the class name that is handling the request. The library does have some interfaces for writing custom loggers.

Notes

In the meantime the library has significantly evolved, current version is 2.4.1, see https://github.com/zalando/logbook/releases. E.g. the default ouput format has changed, and can be configured, filtered, etc.

Do NOT forget to set the log level to TRACE, else you won't see anything:

logging:
  level:
    org.zalando.logbook: TRACE

added as a dependency to a minimal spring boot app and tried to run - no change, no logging output at all in my app. I think there are some additional dependencies or classes this needs? Registering it as a filter doesn't seem to do anything either.
@eis You need to register it as a filter as explained in the docs here. github.com/zalando/logbook
Logbook doc says: "Logbook comes with a convenient auto configuration for Spring Boot users. It sets up all of the following parts automatically with sensible defaults." But it does not work.
@LeosLiterak I believe you need to add logging.level.org.zalando.logbook=TRACE to your application.properties (as is stated in the Readme)
Logbook autoconfiguration doesn't seem to work for spring-boot v2.0.5

I had defined logging level in application.properties to print requests/responses, method url in the log file

logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate.SQL=INFO
logging.file=D:/log/myapp.log

I had used Spring Boot.


Yes, you are right - this is valid answer for get requests logging to the same log file with all other results. However, @moreo asked to log GET, POST, etc. and to the separate file (as I understand)
If you want the headers to be included in the log, then you should add: "spring.http.log-request-details=true" to you application.properties file.

Here is how I do it in spring data rest by using org.springframework.web.util.ContentCachingRequestWrapper and org.springframework.web.util.ContentCachingResponseWrapper

/**

 * There is also {@link org.springframework.web.filter.CommonsRequestLoggingFilter}  but it cannot log request method

  private int maxPayloadLength = 1000;

  private String getContentAsString(byte[] buf, int maxLength, String charsetName) {
    if (buf == null || buf.length == 0) return "";
    int length = Math.min(buf.length, this.maxPayloadLength);
    try {
      return new String(buf, 0, length, charsetName);
    } catch (UnsupportedEncodingException ex) {
      return "Unsupported Encoding";
    }
  }

  /**

    // ========= Log request and response payload ("body") ========
    // We CANNOT simply read the request payload here, because then the InputStream would be consumed and cannot be read again by the actual processing/server.

    // So we need to apply some stronger magic here :-)
    ContentCachingRequestWrapper wrappedRequest = new ContentCachingRequestWrapper(request);
    ContentCachingResponseWrapper wrappedResponse = new ContentCachingResponseWrapper(response);

    filterChain.doFilter(wrappedRequest, wrappedResponse);     // ======== This performs the actual request!
    long duration = System.currentTimeMillis() - startTime;

This works well for response logging - although I had to put a limit on the number of bytes it logs otherwise it trashes the Intellij logging console output.
String getContent() { if (bos == null) { return String.format("called %s too early", BufferedResponseWrapper.class.getCanonicalName()); } byte[] bytes = bos.toByteArray(); return new String(Arrays.copyOf(bytes, 5000)) + "...."; }
It's also worth putting in a "log.isTraceEnabled()" switch around the logging too.
What would be cool is if Java added some default methods to HttpServletResponse so we don't need to write such a huge implementation.
plus one for including the import statements

If you dont mind trying Spring AOP, this is something I have been exploring for logging purposes and it works pretty well for me. It wont log requests that have not been defined and failed request attempts though.

Add these three dependencies

spring-aop, aspectjrt, aspectjweaver

Add this to your xml config file <aop:aspectj-autoproxy/>

Create an annotation which can be used as a pointcut

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD,ElementType.TYPE})
public @interface EnableLogging {
ActionType actionType();
}

Now annotate all your rest API methods which you want to log

@EnableLogging(actionType = ActionType.SOME_EMPLOYEE_ACTION)
@Override
public Response getEmployees(RequestDto req, final String param) {
...
}

Now on to the Aspect. component-scan the package which this class is in.

@Aspect
@Component
public class Aspects {

@AfterReturning(pointcut = "execution(@co.xyz.aspect.EnableLogging * *(..)) && @annotation(enableLogging) && args(reqArg, reqArg1,..)", returning = "result")
public void auditInfo(JoinPoint joinPoint, Object result, EnableLogging enableLogging, Object reqArg, String reqArg1) {

    HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
            .getRequest();

    if (result instanceof Response) {
        Response responseObj = (Response) result;

    String requestUrl = request.getScheme() + "://" + request.getServerName()
                + ":" + request.getServerPort() + request.getContextPath() + request.getRequestURI()
                + "?" + request.getQueryString();

String clientIp = request.getRemoteAddr();
String clientRequest = reqArg.toString();
int httpResponseStatus = responseObj.getStatus();
responseObj.getEntity();
// Can log whatever stuff from here in a single spot.
}


@AfterThrowing(pointcut = "execution(@co.xyz.aspect.EnableLogging * *(..)) && @annotation(enableLogging) && args(reqArg, reqArg1,..)", throwing="exception")
public void auditExceptionInfo(JoinPoint joinPoint, Throwable exception, EnableLogging enableLogging, Object reqArg, String reqArg1) {

    HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
            .getRequest();

    String requestUrl = request.getScheme() + "://" + request.getServerName()
    + ":" + request.getServerPort() + request.getContextPath() + request.getRequestURI()
    + "?" + request.getQueryString();

    exception.getMessage();
    exception.getCause();
    exception.printStackTrace();
    exception.getLocalizedMessage();
    // Can log whatever exceptions, requests, etc from here in a single spot.
    }
}

@AfterReturning advice runs when a matched method execution returns normally. @AfterThrowing advice runs when a matched method execution exits by throwing an exception.

Currently Spring Boot has the Actuator feature to get the logs of requests and responses.

But you can also get the logs using Aspect(AOP).

Aspect provides you with annotations like: @Before, @AfterReturning, @AfterThrowing etc.

@Before logs the request, @AfterReturning logs the response and @AfterThrowing logs the error message, You may not need all endpoints' log, so you can apply some filters on the packages.

Here are some examples:

For Request:

@Before("within(your.package.where.endpoints.are..*)")
    public void endpointBefore(JoinPoint p) {
        if (log.isTraceEnabled()) {
            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " START");
            Object[] signatureArgs = p.getArgs();


            ObjectMapper mapper = new ObjectMapper();
            mapper.enable(SerializationFeature.INDENT_OUTPUT);
            try {

                if (signatureArgs[0] != null) {
                    log.trace("\nRequest object: \n" + mapper.writeValueAsString(signatureArgs[0]));
                }
            } catch (JsonProcessingException e) {
            }
        }
    }

Here @Before("within(your.package.where.endpoints.are..*)") has the package path. All endpoints within this package will generate the log.

For Response:

@AfterReturning(value = ("within(your.package.where.endpoints.are..*)"),
            returning = "returnValue")
    public void endpointAfterReturning(JoinPoint p, Object returnValue) {
        if (log.isTraceEnabled()) {
            ObjectMapper mapper = new ObjectMapper();
            mapper.enable(SerializationFeature.INDENT_OUTPUT);
            try {
                log.trace("\nResponse object: \n" + mapper.writeValueAsString(returnValue));
            } catch (JsonProcessingException e) {
                System.out.println(e.getMessage());
            }
            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " END");
        }
    }

Here @AfterReturning("within(your.package.where.endpoints.are..*)") has the package path. All endpoints within this package will generate the log. Also Object returnValue contains the response.

For Exception:

@AfterThrowing(pointcut = ("within(your.package.where.endpoints.are..*)"), throwing = "e")
public void endpointAfterThrowing(JoinPoint p, Exception e) throws DmoneyException {
    if (log.isTraceEnabled()) {
        System.out.println(e.getMessage());

        e.printStackTrace();


        log.error(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " " + e.getMessage());
    }
}

Here @AfterThrowing(pointcut = ("within(your.package.where.endpoints.are..*)"), throwing = "e") has the package path. All endpoints within this package will generate the log. Also Exception e contains the error response.

Here is the full code:

            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " START");
            Object[] signatureArgs = p.getArgs();


            ObjectMapper mapper = new ObjectMapper();
            mapper.enable(SerializationFeature.INDENT_OUTPUT);
            try {

                if (signatureArgs[0] != null) {
                    log.trace("\nRequest object: \n" + mapper.writeValueAsString(signatureArgs[0]));
                }
            } catch (JsonProcessingException e) {
            }
        }
    }

    @AfterReturning(value = ("within(your.package.where.is.endpoint..*)"),
            returning = "returnValue")
    public void endpointAfterReturning(JoinPoint p, Object returnValue) {
        if (log.isTraceEnabled()) {
            ObjectMapper mapper = new ObjectMapper();
            mapper.enable(SerializationFeature.INDENT_OUTPUT);
            try {
                log.trace("\nResponse object: \n" + mapper.writeValueAsString(returnValue));
            } catch (JsonProcessingException e) {
                System.out.println(e.getMessage());
            }
            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " END");
        }
    }


    @AfterThrowing(pointcut = ("within(your.package.where.is.endpoint..*)"), throwing = "e")
    public void endpointAfterThrowing(JoinPoint p, Exception e) throws Exception {
        if (log.isTraceEnabled()) {
            System.out.println(e.getMessage());

            e.printStackTrace();


            log.error(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " " + e.getMessage());
        }
    }
}

Here, using @ConditionalOnExpression("${endpoint.aspect.enabled:true}") you can enable/disable the log. just add endpoint.aspect.enabled:true into the application.property and control the log

After adding Actuators to the spring boot bassed application you have /trace endpoint available with latest requests informations. This endpoint is working based on TraceRepository and default implementation is InMemoryTraceRepository that saves last 100 calls. You can change this by implementing this interface by yourself and make it available as a Spring bean. For example to log all requests to log (and still use default implementation as a basic storage for serving info on /trace endpoint) I'm using this kind of implementation:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.actuate.trace.InMemoryTraceRepository;
import org.springframework.boot.actuate.trace.Trace;
import org.springframework.boot.actuate.trace.TraceRepository;
import org.springframework.stereotype.Component;

import java.util.List;
import java.util.Map;


@Component
public class LoggingTraceRepository implements TraceRepository {

  private static final Logger LOG = LoggerFactory.getLogger(LoggingTraceRepository.class);
  private final TraceRepository delegate = new InMemoryTraceRepository();

  @Override
  public List<Trace> findAll() {
    return delegate.findAll();
  }

  @Override
  public void add(Map<String, Object> traceInfo) {
    LOG.info(traceInfo.toString());
    this.delegate.add(traceInfo);
  }
}

This traceInfo map contains basic informations about request and response in this kind of form: {method=GET, path=/api/hello/John, headers={request={host=localhost:8080, user-agent=curl/7.51.0, accept=*/*}, response={X-Application-Context=application, Content-Type=text/plain;charset=UTF-8, Content-Length=10, Date=Wed, 29 Mar 2017 20:41:21 GMT, status=200}}}. There is NO response content here.

EDIT! Logging POST data

You can access POST data by overriding WebRequestTraceFilter, but don't think it is a good idea (e.g. all uploaded file content will go to logs) Here is sample code, but don't use it:

package info.fingo.nuntius.acuate.trace;

import org.apache.commons.io.IOUtils;
import org.springframework.boot.actuate.trace.TraceProperties;
import org.springframework.boot.actuate.trace.TraceRepository;
import org.springframework.boot.actuate.trace.WebRequestTraceFilter;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.nio.charset.Charset;
import java.util.LinkedHashMap;
import java.util.Map;

  }

What about POST body?
@dart I've added example for you
I was doing something like this, but the problem is the response body is not available to TraceRepository, how can we access to that?
@AmirPashazadeh you have to override protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) but I'm not sure when this filter is executed - may be on request phase, so response body won't be ready there.
@Kekar Since 2.0 there is HttpTraceRepository (instead of TraceRepository)

Please refer to below link for actual answer https://gist.github.com/int128/e47217bebdb4c402b2ffa7cc199307ba

Made some changes from above referred solution , request and response will log in console and in file too if logger level is info. we can print either in console or file.

Great answer, only suggestion would be to collect all the output into a buffer and log in a single statement.
what if the api is returning Huge Stream of File. how to handle that?

Here my solution (Spring 2.0.x)

Add the maven dependency:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

Edit the application.properties and add the following line:

management.endpoints.web.exposure.include=* 

Once your spring boot application is started you can track the latest 100 http requests by calling this url: http://localhost:8070/actuator/httptrace


This does not show the request body i suppose.
You also need to add an InMemoryHttpTraceRepository Bean. See: juplo.de/actuator-httptrace-does-not-work-with-spring-boot-2-2
d
diogo

You can also configure a custom Spring interceptor HandlerInterceptorAdapter for a simplified implementation of pre-only/post-only interceptors:

@Component
public class CustomHttpInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle (final HttpServletRequest request, final HttpServletResponse response,
            final Object handler)
            throws Exception {

        // Logs here

        return super.preHandle(request, response, handler);
    }

    @Override
    public void afterCompletion(final HttpServletRequest request, final HttpServletResponse response,
            final Object handler, final Exception ex) {
        // Logs here
    }
}

Then, you register as many interceptors as you want:

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Autowired
    CustomHttpInterceptor customHttpInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(customHttpInterceptor).addPathPatterns("/endpoints");
    }

}

Note: just like stated by @Robert, you need to pay attention to the specific implementations of HttpServletRequest and HttpServletResponse your application is using.

For example, for apps using the ShallowEtagHeaderFilter, the response implementation would be a ContentCachingResponseWrapper, so you'd have:

@Component
public class CustomHttpInterceptor extends HandlerInterceptorAdapter {

    private static final Logger LOGGER = LoggerFactory.getLogger(CustomHttpInterceptor.class);

    private static final int MAX_PAYLOAD_LENGTH = 1000;

    @Override
    public void afterCompletion(final HttpServletRequest request, final HttpServletResponse response,
            final Object handler, final Exception ex) {
        final byte[] contentAsByteArray = ((ContentCachingResponseWrapper) response).getContentAsByteArray();

        LOGGER.info("Request body:\n" + getContentAsString(contentAsByteArray, response.getCharacterEncoding()));
    }

    private String getContentAsString(byte[] buf, String charsetName) {
        if (buf == null || buf.length == 0) {
            return "";
        }

        try {
            int length = Math.min(buf.length, MAX_PAYLOAD_LENGTH);

            return new String(buf, 0, length, charsetName);
        } catch (UnsupportedEncodingException ex) {
            return "Unsupported Encoding";
        }
    }

}

the code pasted below works with my tests and can be downloaded from my [github project][1], sharing after applying a solution based on that on a production project.

@Configuration
public class LoggingFilter extends GenericFilterBean {

    /**
     * It's important that you actually register your filter this way rather then just annotating it
     * as @Component as you need to be able to set for which "DispatcherType"s to enable the filter

     * 
     * @return
     */
    @Bean
    public FilterRegistrationBean<LoggingFilter> initFilter() {
        FilterRegistrationBean<LoggingFilter> registrationBean = new FilterRegistrationBean<>();
        registrationBean.setFilter(new LoggingFilter());

        // *1* make sure you sett all dispatcher types if you want the filter to log upon
        registrationBean.setDispatcherTypes(EnumSet.allOf(DispatcherType.class));

        // *2* this should put your filter above any other filter
        registrationBean.setOrder(Ordered.HIGHEST_PRECEDENCE);

        return registrationBean;
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {

        ContentCachingRequestWrapper wreq = 
            new ContentCachingRequestWrapper(
                (HttpServletRequest) request);

        ContentCachingResponseWrapper wres = 
            new ContentCachingResponseWrapper(
                (HttpServletResponse) response);

        try {

            // let it be ...
            chain.doFilter(wreq, wres);

            // makes sure that the input is read (e.g. in 404 it may not be)
            while (wreq.getInputStream().read() >= 0);

            System.out.printf("=== REQUEST%n%s%n=== end request%n",
                    new String(wreq.getContentAsByteArray()));

            // Do whatever logging you wish here, in this case I'm writing request 
            // and response to system out which is probably not what you wish to do
            System.out.printf("=== RESPONSE%n%s%n=== end response%n",
                    new String(wres.getContentAsByteArray()));

            // this is specific of the "ContentCachingResponseWrapper" we are relying on, 
            // make sure you call it after you read the content from the response
            wres.copyBodyToResponse();

            // One more point, in case of redirect this will be called twice! beware to handle that
            // somewhat

        } catch (Throwable t) {
            // Do whatever logging you whish here, too
            // here you should also be logging the error!!!
            throw t;
        }

    }

If somebody still need it here is simple implementation with Spring HttpTrace Actuator. But as they have told upper it doesn't log bodies.

import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.builder.ToStringBuilder;
import org.springframework.boot.actuate.trace.http.HttpTrace;
import org.springframework.boot.actuate.trace.http.InMemoryHttpTraceRepository;
import org.springframework.stereotype.Repository;

@Slf4j
@Repository
public class LoggingInMemoryHttpTraceRepository extends InMemoryHttpTraceRepository {
    public void add(HttpTrace trace) {
        super.add(trace);
        log.info("Trace:" + ToStringBuilder.reflectionToString(trace));
        log.info("Request:" + ToStringBuilder.reflectionToString(trace.getRequest()));
        log.info("Response:" + ToStringBuilder.reflectionToString(trace.getResponse()));
    }
}

no response body

@hahn's answer required a bit of modification for it to work for me, but it is by far the most customizable thing I could get.

It didn't work for me, probably because I also have a HandlerInterceptorAdapter[??] but I kept getting a bad response from the server in that version. Here's my modification of it.

public class LoggableDispatcherServlet extends DispatcherServlet {

    private final Log logger = LogFactory.getLog(getClass());

    @Override
    protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {

        long startTime = System.currentTimeMillis();
        try {
            super.doDispatch(request, response);
        } finally {
            log(new ContentCachingRequestWrapper(request), new ContentCachingResponseWrapper(response),
                    System.currentTimeMillis() - startTime);
        }
    }

    private void log(HttpServletRequest requestToCache, HttpServletResponse responseToCache, long timeTaken) {
        int status = responseToCache.getStatus();
        JsonObject jsonObject = new JsonObject();
        jsonObject.addProperty("httpStatus", status);
        jsonObject.addProperty("path", requestToCache.getRequestURI());
        jsonObject.addProperty("httpMethod", requestToCache.getMethod());
        jsonObject.addProperty("timeTakenMs", timeTaken);
        jsonObject.addProperty("clientIP", requestToCache.getRemoteAddr());
        if (status > 299) {
            String requestBody = null;
            try {
                requestBody = requestToCache.getReader().lines().collect(Collectors.joining(System.lineSeparator()));
            } catch (IOException e) {
                e.printStackTrace();
            }
            jsonObject.addProperty("requestBody", requestBody);
            jsonObject.addProperty("requestParams", requestToCache.getQueryString());
            jsonObject.addProperty("tokenExpiringHeader",
                    responseToCache.getHeader(ResponseHeaderModifierInterceptor.HEADER_TOKEN_EXPIRING));
        }
        logger.info(jsonObject);
    }
}

is your application packaged as war or jar? I keep getting the error java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/loggingDispatcherServlet-servlet.xml]

Has there been any development with Actuator HTTP Trace since the initial question was posted i.e. is there a way to enrich it with the response body?

What about enriching it with custom metadata from MDC or from Spring-Sleuth or Zipkin, such as traceId and spanId?

Also for me Actuator HTTP Trace didn't work Spring Boot 2.2.3, and I found the fix here: https://juplo.de/actuator-httptrace-does-not-work-with-spring-boot-2-2/

pom.xml

<dependency>
  <groupId>org.springframework.boot
  <artifactId>spring-boot-starter-actuator
</dependency>

application.properties

management.endpoints.web.exposure.include=httptrace

The fix:

The simple fix for this problem is, to add a @Bean of type InMemoryHttpTraceRepository to your @Configuration-class:

@Bean
public HttpTraceRepository htttpTraceRepository()
{
  return new InMemoryHttpTraceRepository();
}

The Explanation:

The cause of this problem is not a bug, but a legitimate change in the default configuration. Unfortunately, this change is not noted in the according section of the documentation. Instead it is burried in the Upgrade Notes for Spring Boot 2.2 The default-implementation stores the captured data in memory. Hence, it consumes much memory, without the user knowing, or even worse: needing it. This is especially undesirable in cluster environments, where memory is a precious good. And remember: Spring Boot was invented to simplify cluster deployments! That is, why this feature is now turned of by default and has to be turned on by the user explicitly, if needed.


This doesn't work with latest Spring Boot. /actuator/ and /actuator/httptrace will still return 404
It appears endpoint was changed to /httptrace. All endpoints: docs.spring.io/spring-boot/docs/2.1.7.RELEASE/reference/html/…
You'll need to find your management.endpoints.web.base-path config if you want to know what the actual endpoint is.
Definitely still needs the HttpTraceRepository Bean in your @Configuration class. Doesn't work without it.

If you are seeing only part of your request payload, you need to call the setMaxPayloadLength function as it defaults to showing only 50 characters in your request body. Also, setting setIncludeHeaders to false is a good idea if you don't want to log your auth headers!

@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
    CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
    loggingFilter.setIncludeClientInfo(false);
    loggingFilter.setIncludeQueryString(false);
    loggingFilter.setIncludePayload(true);
    loggingFilter.setIncludeHeaders(false);
    loggingFilter.setMaxPayloadLength(500);
    return loggingFilter;
}

I am trying to use it in spring mvc and it's not working for me, It is required any additional setting except registering this bean and adding logger?

Brad Mace

As suggested previously, Logbook is just about perfect for this, but I did have a little trouble setting it up when using Java modules, due to a split package between logbook-api and logbook-core.

For my Gradle + Spring Boot project, I needed

build.gradle

dependencies {
    compileOnly group: 'org.zalando', name: 'logbook-api', version: '2.4.1'
    runtimeOnly group: 'org.zalando', name: 'logbook-spring-boot-starter', version: '2.4.1'
    //...
}

logback-spring.xml

<configuration>
    <!-- HTTP Requests and Responses -->
    <logger name="org.zalando.logbook" level="trace" />
</configuration>

In order to log all the requests with input parameters and body, we can use filters and interceptors. But while using a filter or interceptor, we cannot print the request body multiple times. The better way is we can use spring-AOP. By using this we can decouple the logging mechanism from the application. AOP can be used for logging Input and output of each method in the application.

My solution is:

 import org.aspectj.lang.ProceedingJoinPoint;
 import org.aspectj.lang.annotation.Around;
 import org.aspectj.lang.annotation.Aspect;
 import org.aspectj.lang.annotation.Pointcut;
 import org.aspectj.lang.reflect.CodeSignature;
 import org.slf4j.Logger;
 import org.slf4j.LoggerFactory;
 import org.springframework.stereotype.Component;
 import com.fasterxml.jackson.databind.ObjectMapper;
 @Aspect
 @Component
public class LoggingAdvice {
private static final Logger logger = 
LoggerFactory.getLogger(LoggingAdvice.class);

//here we can provide any methodName, packageName, className 
@Pointcut(value = "execution(* com.package.name.*.*.*(..) )")
public void myPointcut() {

}

@Around("myPointcut()")
public Object applicationLogger(ProceedingJoinPoint pjt) throws Throwable {
    ObjectMapper mapper = new ObjectMapper();
    String methodName = pjt.getSignature().getName();
    String className = pjt.getTarget().getClass().toString();
    String inputParams = this.getInputArgs(pjt ,mapper);
    logger.info("method invoked from " + className + " : " + methodName + "--Request Payload::::"+inputParams);
    Object object = pjt.proceed();
    try {
        logger.info("Response Object---" + mapper.writeValueAsString(object));
    } catch (Exception e) {
    }
    return object;
}

private String getInputArgs(ProceedingJoinPoint pjt,ObjectMapper mapper) {
    Object[] array = pjt.getArgs();
    CodeSignature signature = (CodeSignature) pjt.getSignature();

    StringBuilder sb = new StringBuilder();
    sb.append("{");
    int i = 0;
    String[] parameterNames = signature.getParameterNames();
    int maxArgs = parameterNames.length;
    for (String name : signature.getParameterNames()) {
        sb.append("[").append(name).append(":");
        try {
            sb.append(mapper.writeValueAsString(array[i])).append("]");
            if(i != maxArgs -1 ) {
                sb.append(",");
            }
        } catch (Exception e) {
            sb.append("],");
        }
        i++;
    }
    return sb.append("}").toString();
}

}


I just answered the same thing and thought maybe best to checkout all the other answers as well. AOP is perfect for logging, as it is cross-cut

if you use Tomcat in your boot app here is org.apache.catalina.filters.RequestDumperFilter in a class path for you. (but it will not provide you "with exceptions in single place").

If you have Spring boot Config server configured then just enable Debug logger for class :

Http11InputBuffer.Http11InputBuffer.java

Debugs will log all the requests and responses for every request


Adding "logging.level.org.apache.coyote.http11=DEBUG" to application.properties logs request & response but any request made to other back end services using restTemplate are not logged same way.

Dharman

Note

 @Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
...
}

approach will not work with spring security filter chains. You have to manually add CommonsRequestLoggingFilter like

protected void configure(HttpSecurity http) throws Exception {
         HttpSecurity filter = http
        .cors().and().addFilterBefore(new CommonsRequestLoggingFilter(), CorsFilter.class);
}

In application.properties I added:

Logging Request + payload in a CUSTOM FORMAT:

For a custom format, just override the super implementation of the Spring logger Bean - org/springframework/web/filter/AbstractRequestLoggingFilter.java

Let's say we whish skipping GET requests and only tracing write requests (PUT, PATCH, DELETE, etc) with INFO log level:

@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
CommonsRequestLoggingFilter logFilter = new CommonsRequestLoggingFilter() {

  @Override
  protected boolean shouldLog(HttpServletRequest request) {
    return logger.isInfoEnabled() && !Objects.equals(request.getMethod(), "GET");
  }


  @Override
  protected void beforeRequest(HttpServletRequest request, String message) {
    // Do nothing if you need logging payload.
    // As, Before the Request, the payload is not read from the input-stream, yet.
  }


  @Override
  protected void afterRequest(HttpServletRequest request, String message) {
    logger.info(message); // Or log to a file here, as OP asks.
  }


  @Override
  protected @NonNull String createMessage(HttpServletRequest request, @NonNull String prefix, @NonNull String suffix) {
    // Output: [PUT][/api/my-entity], user:[my-loging], payload was:[{ "id": 33, "value": 777.00}]
    StringBuilder msg = new StringBuilder()
        .append(prefix)
        .append("[").append(request.getMethod()).append("]")
        .append("[").append(request.getRequestURI()).append("]");

    String user = request.getRemoteUser();
    msg.append(", user:[").append(null == user ? "" : user).append("]");

    String payload = getMessagePayload(request);
    if (payload != null) {
      // It's not null on After event. As, on Before event, the Input stream was not read, yet.
      msg.append(", payload was:[").append(payload.replace("\n", "")).append("]");  // Remove /n to be compliant with elastic search readers.
    }

    msg.append(suffix);
    return msg.toString();
  }
};
logFilter.setBeforeMessagePrefix("Incoming REST call: -->>>[");
logFilter.setBeforeMessageSuffix("]...");
logFilter.setAfterMessagePrefix("REST call processed: -<<<[");
logFilter.setAfterMessageSuffix("]");
logFilter.setIncludePayload(true);
logFilter.setMaxPayloadLength(64000);
return logFilter;
}

You can use Actuator in Spring Boot.
It logs requests and responses and more information about servlet and system operating.
You just add it as a dependency of your project and config, if more details needed to log.
Take a look at this example:
Actuator in Spring Boot example


actuator doesn't log the body of the request or response.
