Spring Batch: Creating A Custom Job Builder

May 18, 2023
Batch Processing

Batch jobs are created in Spring Batch using the JobBuilderFactory. A custom job builder factory can be created and re-used to allow common job configurations to be shared across all batch jobs in a project.

Example

@Configuration
public class CustomJobBuilderFactory extends JobBuilderFactory {

    @Override
    public JobBuilder get(final String name) {
        final JobBuilder jobBuilder = super.get(name);
	// register common to all jobs things here
        jobBuilder.listener(commonListener);
	return jobBuilder;
    }
}

Implementation


    @Bean
    public Job exampleJob(final CustomJobBuilderFactory jbf) {
	// This job now has the common listener 
	return jbf.get("myJob").start(myStep).build();
    }
}
