Answer 1

You can also make your CommandLineRunner implementations @Component and @ConditionalOnExpression("${someproperty:false}")

then have multiple profiles, that set someproperty to true to include those CommandLineRunners in the Context.

@Component
@Slf4j
@ConditionalOnExpression("${myRunnerEnabled:false}")
public class MyRunner implements CommandLineRunner {
    @Override
    public void run(String ... args) throws Exception {
        log.info("this ran");
    }
}

and in the yml application-myrunner.yml

myRunnerEnabled: true

@SpringBootApplication
public class SpringMain {
    public static void main(String ... args) {
        SpringApplication.run(SpringMain.class, args);
    }
}
