Spring batch with multiple main and scheduler

I am working on a Spring Batch project that has two Main classes with @SpringBootApplication in it. I also have to use the @Scheduler and associate it only with one Main class. But the issue here is no matter which class I run, the scheduler is getting executed. Snippets below,

MainApp1.java

@SpringBootApplication

@EnableScheduling

public class MainApp1{



    public static void main(String args) {





        SpringApplication.run(MainApp1.class, args);

    }

}

MainApp2.java

@SpringBootApplication



    public class MainApp2{



        public static void main(String args) {



            SpringApplication.run(MainApp2.class, args);

        }

    }

Scheduler.java

@Configuration

public class TmsBatchSenderScheduler {



    @Scheduled(fixedDelay = 5000)

    public void myScheduler() {



    }

}

I think what's happening here is the scheduler is getting created for both mains because of the @Configuration annotation. Is there a way to achieve this? I want the scheduler to run only when the MainApp1 is run.

Thanks in advance :)

How do you run the app? Is it with java -jar yourapp.jar? The spring-boot-maven-plugin should fail in the repackage phase if it finds two main classes in your project and you would need to specify which one to use (See how in docs.spring.io/spring-boot/docs/2.1.0.RELEASE/maven-plugin/…). Have you tried to move each app to a separate package (See docs.spring.io/spring-boot/docs/2.1.0.RELEASE/reference/…)?

Haven't done that much yet. Currently I am running them from STS separately.

ok in that case, try to put each app in its own package.

Try @EnableAutoConfiguration(exclude=TaskSchedulingAutoConfiguration.class) in the class where you don't need scheduling. I really recommend creating a spring boot app for each app, so much complexity in software comes from trying to make one thing do two things.
