Set root logging level in application.yml

You can use ROOT to configure the root logging level:

logging:
  level:
    ROOT: DEBUG

---

If you want level by package, you can use this syntax :

logging:
  level:
     org.springframework.web: DEBUG
     guru.springframework.controllers: DEBUG
     org.hibernate: DEBUG
     org: INFO

---

You can even use your classname to configure logging level:

logging:
  level:
    com.yourorganization.Yourclass: DEBUG

---

It's an old question, but I just had this problem.

While setting

org.springframework.web: debug

or

org.hibernate: debug

works fine, if you want to do the same for your project files (setting level per package), you have to use wildcards. So, for the example in the question, it would be:

logging:
    level:
        root: WARN
        com.filenet.wcm.*: ERROR
        de.mycompany.*: DEBUG

Alternatively, you can set the logging level per class without using wildcards, as shown in torina's answer.

You can log incoming request by creating CommonsRequestLoggingFilter and adding

logging.level.org.springframework.web.filter.CommonsRequestLoggingFilter=DEBUG

to application.properties file as explained in detail in this link - https://www.baeldung.com/spring-http-logging

@Configuration
public class RequestLoggingFilterConfig {

    @Bean
    public CommonsRequestLoggingFilter logFilter() {
        CommonsRequestLoggingFilter filter
          = new CommonsRequestLoggingFilter();
        filter.setIncludeQueryString(true);
        filter.setIncludePayload(true);
        filter.setMaxPayloadLength(10000);
        filter.setIncludeHeaders(false);
        filter.setAfterMessagePrefix("REQUEST DATA : ");
        return filter;
    }
}
