Set spring profile in IntelliJ

To set the spring profile in IntelliJ, just edit the configuration, usually spring-boot:run if you are using maven, or bootRun if you are using gradle, and add the environment variable SPRING_PROFILES_ACTIVE. In the below example SPRING_PROFILES_ACTIVE=dev, the spring profile is set to dev.

And to confirm that the profile is really activated, check that the log The following 1 profile is active: followed by the activated profile name. Example - [demo] [ main] com.example.demo.DemoApplication : The following 1 profile is active: "dev".
