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

我正在通过 CommandLineRunner 运行一个 Spring 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 无法完成,我将使用 --restart 参数重新运行该作业,它应该找到上一次执行并恢复 jobExecution 而不是创建一个新的 jobInstance .

下面是我的JobConfig类 .

@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 .

我没有 --restart 参数运行作业,一切运行正常 . 接下来,当我故意失败工作并尝试使用 --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 .

BATCH_JOB_EXECUTION table

我通过程序调试 jobInstanceIdjobExecutionId 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 .

只是为了更清楚 . 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();

  }

}
