The first thing to do is @Inject the Spring Environment into your own Spring bean.
@Inject
private Environment environment;
Now you can ask the environment whether a given profile is active or not:
if (Arrays.asList(environment.getActiveProfiles()).contains("dev")) {
LOG.info("Profile 'dev' is active");
...
}
A helpful colleague pointed out that this is a bit cumbersome and suggested to use the more readable form:
if (env.acceptsProfiles("dev")) {
LOG.info("Profile 'dev' is active");
...
}
