I recently had to create a dev version of our application, that should run with dev active profile out of the box without any command line args. I solved it with adding this one class as a new entry, which sets the active profile programmatically:

package ...;

import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.Import;
import org.springframework.core.env.ConfigurableEnvironment;
import org.springframework.core.env.StandardEnvironment;

@Import(OriginalApplication.class)
public class DevelopmentApplication {
    public static void main(String[] args) {
        SpringApplication application =
            new SpringApplication(DevelopmentApplication.class);
        ConfigurableEnvironment environment = new StandardEnvironment();
        environment.setActiveProfiles("dev");
        application.setEnvironment(environment);
        application.run(args);
    }
}
