尝试重新启动spring批处理作业时出现NoSuchJobException

Question

我正在通过CommandLineRunner运行春季批处理作业。我希望我的工作运行的方式是每次运行创建一个新的JobInstance，如果jobExecution未能完成，我将使用--restart参数重新运行该作业，它应该找到之前的执行并恢复jobExecution，而不是创建新的jobInstance。

以下是我的JobConfig课程。

@Slf4j
@Configuration
public class JobConfig {

  @Autowired
  List<Job> jobsToRun; //Jobs annotated as a Components

  @Bean
  public CommandLineRunner commandLineRunner(JobLauncher jobLauncher,
      JobRepository jobRepository, JobOperator jobOperator, JobExplorer jobExplorer) {
    return args -> {
      JobParameters parameters = new JobParametersBuilder()
          .addLong("timestamp", System.currentTimeMillis())
          .toJobParameters();
      SimpleCommandLinePropertySource cli = new SimpleCommandLinePropertySource(args);
      jobsToRun.forEach(job -> {
        try {
          if (!cli.containsProperty("restart")) {
            jobLauncher.run(job, parameters);
          } else {
            long jobInstanceId = jobOperator.getJobInstances(job.getName(), 0, 1).get(0);
            long lastExecutionId = jobOperator.getExecutions(jobInstanceId).get(0);
            if (jobExplorer.getJobExecution(lastExecutionId).getStatus() == BatchStatus.FAILED) {
              jobOperator.restart(lastExecutionId);
              log.info("Restarting the job " + job.getName());
            } else {
              log.warn("Cannot restart the job. Job not in Failed state.");
            }
          }
        } catch (JobExecutionAlreadyRunningException | JobRestartException | JobInstanceAlreadyCompleteException | JobParametersInvalidException e) {
          log.error(
              "Error occured while running job " + job.getName() + " Reason: " + e.getMessage());
        } catch (NoSuchJobException | NoSuchJobInstanceException | NoSuchJobExecutionException e) {
          e.printStackTrace();
        }
      });

    };
  }
}

此配置收集我的所有作业bean并通过此CommandLineRunner bean运行它们。

我在没有--restart参数的情况下运行作业，一切运行正常。 接下来，当我故意将工作失败并尝试使用--restart参数运行时，应用程序会抛出org.springframework.batch.core.launch.NoSuchJobException: No job configuration with the name [itemJob] was registered。

我通过程序调试jobInstanceId，而jobExecutionId似乎是正确的ID。一个重要的是应用程序不会将任何内容记录为错误。我只是在INFO级别获得此异常。不知道我在这里错过了什么。

更清楚。如果可能有帮助，我还在这里包含一个作业组件bean。

@Component
@Slf4j
@Profile("master")
@ConditionalOnProperty(name = "item", havingValue = "true")
public class ItemImportJob {

  @Autowired
  private JobBuilderFactory jobBuilderFactory;

  @Autowired
  private ItemRemotePartition itemRemotePartition;

  @Bean
  @Profile("master")
  public Job itemJob() throws Exception {
    return jobBuilderFactory.get("itemJob").listener(new JobExecutionListener() {
      @Override
      public void beforeJob(JobExecution jobExecution) {
        log.info("Ready to start the job");
      }

      @Override
      public void afterJob(JobExecution jobExecution) {
        log.info("Job successfully executed.");
      }
    }).incrementer(new RunIdIncrementer())
        .start(itemRemotePartition.masterStep())
        .build();

  }

}
