How to run Spring Batch Jobs in certain order (Spring Boot)?

Question

I\'m developing with Spring Batch using Spring Boot.

I\'m with the minimal configuration provided by Spring Boot and defined some Jobs (no XML configuration at all).

I don't have enough rep to comment. But have you tried just to manually launch your jobs in the order you want?

You need to set spring.batch.job.enabled=false in your application.properties, so that your jobs are not run automatically.

Then just use a launcher to launch your jobs in the order you want.

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { TestConfiguration.class, TestDataSourceConfiguration.class, TestBatchConfig.class })
public class JobOrderTest {

    @Autowired
    JobLauncher jobLauncher;

    @Mock
    Job firstJob;

    @Mock
    Job secondJob;

    @Mock
    Job thirdJob;

    @Mock
    JobParametersValidator jobParametersValidator;

    @Test
    public void jobInOrderTest() throws JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException, JobParametersInvalidException {

        when(firstJob.getName()).thenReturn(UUID.randomUUID().toString());
        when(secondJob.getName()).thenReturn(UUID.randomUUID().toString());
        when(thirdJob.getName()).thenReturn(UUID.randomUUID().toString());
        when(firstJob.getJobParametersValidator()).thenReturn(jobParametersValidator);
        when(secondJob.getJobParametersValidator()).thenReturn(jobParametersValidator);
        when(thirdJob.getJobParametersValidator()).thenReturn(jobParametersValidator);

        jobLauncher.run(firstJob, new JobParameters());
        jobLauncher.run(secondJob, new JobParameters());
        jobLauncher.run(thirdJob, new JobParameters());
    }

}

Here is the output
