spring批处理在10秒后停止作业

Question

我正在尝试在后台运行作业，允许我根据某种条件或在超时发生后停止它。

我有这两块代码：

@ContextConfiguration(classes={EmbeddedISpringBatchConfiguration.class, MonitoredJobConfig.class})
@RunWith(SpringJUnit4ClassRunner.class)
public class RunMonitoredJob2 {

@Autowired
private JobLauncher jobLauncher;

@Autowired
private JobRepository jobRepository;

@Autowired
private Job job;

@Test
public void testLaunchJob() throws Exception {

    JobExecution execution = jobLauncher.run(job, new JobParameters());

    Thread.sleep(10000);

    execution.stop();
}

@ContextConfiguration(classes={EmbeddedISpringBatchConfiguration.class, MonitoredJobConfig.class})
@RunWith(SpringJUnit4ClassRunner.class)
public class RunMonitoredJob {

@Autowired
private JobRepository jobRepository;

@Autowired
private Job job;

@Test
public void testLaunchJob() throws Exception {

    JobExecution execution = jobLauncher().run(job, new JobParameters());

    Thread.sleep(10000);

    execution.stop();
}

public JobLauncher jobLauncher() {
    final SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
    jobLauncher.setJobRepository(jobRepository);
    final SimpleAsyncTaskExecutor simpleAsyncTaskExecutor = new SimpleAsyncTaskExecutor();
    jobLauncher.setTaskExecutor(simpleAsyncTaskExecutor);
    return jobLauncher;
}

尝试使用scheduler，它将在特定时间间隔后调用，而不是使用Thread.Sleep

@Scheduled(fixedDelayString = "${cron.batch-timeout-check-delay}", initialDelayString = "${cron.batch-timeout-check-initial-delay}")
    public void execute() throws Exception{
      //get jobExceutionId of job to stop
      JobExceution jobExecution = jobExplorer.getJobExceution(jobExceutionId);
      boolean isTimeout = (new Date().getTime() - jobExecution.getCreateTime().getTime()) > 50000 //Here timout
      if(isTimeout){
        jobexceution.stop();
      }
    }
