spring.profiles.active not honoured

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.

Solution

  • 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.
