Java Dailly Tip: Setting active profile and config location from command line in spring boot

Problem

I wrote an application in spring. The application has three profiles to run, so I have three files:

1. application-development.yml
2. application-staging.yml
3. application-production.yml

The files are located in the / src / main / resources directory. I am using the Gradle plugin for the eclipse. When I try to "bootRun" I set the command line arguments in my eclipse gradle configuration as:

-Dspring.profiles.active = staging -Dspring.config.location = src / main / resources / application-production.yml

However, the command line property is not mirrored and my active profile is always set as developer (which I mentioned in application.yml). What am I missing?

Solution

My best practice is to define this as a VM "-D" argument:

-Dspring-boot.run.profiles=local
mvn spring-boot:run -Dspring-boot.run.profiles=local

Make sure to separate them with a comma for multiple profiles:

mvn spring-boot:run -Dspring.profiles.active=local,foo,bar

There's another way by setting the OS environment variable, SPRING_PROFILES_ACTIVE.

SPRING_PROFILES_ACTIVE=dev gradle clean bootRun

For gradle:

bootRun {
    String activeProfile =  System.properties['spring.profiles.active']
    String confLoc = System.properties['spring.config.location']
    systemProperty "spring.profiles.active", activeProfile
    systemProperty "spring.config.location", "file:$confLoc"
}
