spring.profiles.active not honoured

Question

In

application.properties 

we have the line

spring.profiles.active=LOCALHOST

In

application-DEV.properties

, we have the line

spring.profiles.active=DEV,dbcache,metrics,AWS

. When running the app with

java -jar app.war -Dspring.profiles.active=DEV

the console output says

The following profiles are active: LOCALHOST

, ie the

-Dspring.profiles.active=DEV 

argument isn't honored, the app still uses the default LOCALHOST profile.

Answer 1

My man page for the java command says:

java [ options ] -jar file.jar [ argument ... ]

That is, JVM options (such as property settings) must go before the -jar (or main class). Anything after that is considered an argument passed to main.

This actually has a purpose and isn't just pedantic--you might have a tool that launches a child JVM (Maven can do this, for example) and want to provide arguments to be passed there.

Answer 2

Just in case some one is having the same issue as me, make sure your main class args is passed into spring. Hope it helps.

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}
