Where to place @EnableBatchProcessing?

I'm using spring-batch for job executions. Does it matter on which class I place the @EnableBatchProcessing(modular = true) annotation?

I would place it on the global ApplicationConfig, or would it be better to put it on the modular batch configuration where the batch job execution context is created? Eg:

@Configuration
public class ModularBatchConfig {
    @Bean
    public ApplicationContextFactory myJob() {
       return new GenericApplicationContextFactory(MyJob.class);
    }
}

In an "application" that contains multiple batch jobs, we recommend putting the @EnableBatchProcessing at the highest level that makes sense. What I mean by that is that @EnableBatchProcessing is going to bootstrap a number of common components (JobRepository, TransactionManager, etc). It's typically better to use these as common components instead of bootstrapping one per job.
