How to set spring.profiles.active in my conte

Answer 1

You can use either a environment variable, system variable (-D option for the JVM or application) or put it in JNDI (java:comp/env/. You cannot however put it in a properties file, as it is needed before the that specific properties file is read.

There is more information in the @Profile javadocs.

Another solution is to create your own ApplicationContextInitializer implementation which reads a certain file and activates the given profile.
