I need to code different logic based on different current Environment profile.
How can you get the currently active and default profiles from Spring?
You can autowire the Environment
@Autowired
Environment env;
Environment
offers:
String[] getActiveProfiles(),
String[] getDefaultProfiles(), and
boolean acceptsProfiles(String... profiles)
Extending User1648825's nice simple answer:
@Value("${spring.profiles.active}")
private String activeProfile;
This may throw an IllegalArgumentException if no profiles are set (I get a null value). This may be a Good Thing if you need it to be set; if not use the 'default' syntax for @Value, ie:
@Value("${spring.profiles.active:Unknown}")
private String activeProfile;
...activeProfile now contains 'Unknown' if spring.profiles.active could not be resolved
Here is a more complete example.
Autowire Environment
First you will want to autowire the environment bean.
@Autowired
private Environment environment;
Check if Profiles exist in Active Profiles
Then you can use getActiveProfiles()
to find out if the profile exists in the list of active profiles. Here is an example that takes the String[]
from getActiveProfiles()
, gets a stream from that array, then uses matchers to check for multiple profiles(Case-Insensitive) which returns a boolean if they exist.
//Check if Active profiles contains "local" or "test"
if(Arrays.stream(environment.getActiveProfiles()).anyMatch(
env -> (env.equalsIgnoreCase("test")
|| env.equalsIgnoreCase("local")) ))
{
doSomethingForLocalOrTest();
}
//Check if Active profiles contains "prod"
else if(Arrays.stream(environment.getActiveProfiles()).anyMatch(
env -> (env.equalsIgnoreCase("prod")) ))
{
doSomethingForProd();
}
You can also achieve similar functionality using the annotation @Profile("local")
Profiles allow for selective configuration based on a passed-in or environment parameter. Here is more information on this technique: Spring Profiles
@Value("${spring.profiles.active}")
private String activeProfile;
It works and you don't need to implement EnvironmentAware. But I don't know drawbacks of this approach.
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.profiles.active' in value "${spring.profiles.active}"
@Profile
. Apps can also use the spring.profiles.include
property, and can set profiles programmatically during initialization using ConfigurableEnvironment
. Environment.getActiveProfiles()
will get the full list of profiles set using any of these mechanisms.
If you're not using autowiring, simply implement EnvironmentAware
As already mentioned earlier. You could autowire Environment:
@Autowired
private Environment environment;
only you could do check for the needed environment much easier:
if (environment.acceptsProfiles(Profiles.of("test"))) {
doStuffForTestEnv();
} else {
doStuffForOtherProfiles();
}
Seems there is some demand to be able to access this statically.
How can I get such thing in static methods in non-spring-managed classes? – Aetherus
It's a hack, but you can write your own class to expose it. You must be careful to ensure that nothing will call SpringContext.getEnvironment()
before all beans have been created, since there is no guarantee when this component will be instantiated.
@Component
public class SpringContext
{
private static Environment environment;
public SpringContext(Environment environment) {
SpringContext.environment = environment;
}
public static Environment getEnvironment() {
if (environment == null) {
throw new RuntimeException("Environment has not been set yet");
}
return environment;
}
}
And if you neither want to use @Autowire nor injecting @Value you can simply do (with fallback included):
System.getProperty("spring.profiles.active", "unknown");
This will return any active profile (or fallback to 'unknown').

acceptsProfiles(String... profiles)
and replaced it withacceptsProfiles(Profiles profiles)
