How to run multiple jobs in spring batch using annotations

The names of the Beans have to be unique in the whole Spring Context.

In both jobs, you are instantiating the reader, writer and processor with the same methodname. The methodname is the name that is used to identifiy the bean in the context.

In both job-definitions, you have reader(), writer() and processor(). They will overwrite each other. Give them unique names like readerEmployee(), readerSalary() and so on.

That should solve your problem.

You jobs are not annotated with @Bean, so the spring-context doesn't know them.

Have a look at the class JobLauncherCommandLineRunner. All Beans in the SpringContext implementing the Job interface will be injected. All jobs that are found will be executed. (this happens inside the method executeLocalJobs in JobLauncherCommandLineRunner)

If, for some reason, you don't want to have them as beans in the context, then you have to register your jobs with the jobregistry.( the method execute registeredJobs of JobLauncherCommandLineRunner will take care of launching the registered jobs)

BTW, you can control with the property

spring.batch.job.names= # Comma-separated list of job names to execute on startup (For instance
 `job1,job2`). By default, all Jobs found in the context are executed.

which jobs should be launched.
