How to use

listener

method

in

org.springframework.batch.core.step.builder.JobStepBuilder

@Test
public void testAnnotationBasedChunkListenerForJobStepBuilder() throws Exception {
  JobRepository jobRepository = new MapJobRepositoryFactoryBean().getObject();
  StepExecution execution = jobRepository.createJobExecution("foo", new JobParameters()).createStepExecution("step");
  jobRepository.add(execution);
  PlatformTransactionManager transactionManager = new ResourcelessTransactionManager();
  SimpleJob job = new SimpleJob("job");
  job.setJobRepository(jobRepository);
  JobStepBuilder builder = new StepBuilder("step")
      .repository(jobRepository)
      .transactionManager(transactionManager)
      .job(job)
      .listener(new AnnotationBasedChunkListener());
  builder.build().execute(execution);
  assertEquals(BatchStatus.COMPLETED, execution.getStatus());
  // it makes no sense to register a ChunkListener on a step which is not of type tasklet, so it should not be invoked
  assertEquals(0, AnnotationBasedChunkListener.beforeChunkCount);
  assertEquals(0, AnnotationBasedChunkListener.afterChunkCount);
}
