Question

我正在尝试使用Spring批处理批处理作业。当我尝试使用stop executionId正在运行的作业时，作业将在SpringBatchDb.BATCH_JOB_EXECUTION表

中以下条目停止

＆＃39; 104＆＃39;，＆＃39; 3＆＃39;，＆＃39; 104＆＃39;，＆＃39; 2017-11-27 11：39：10＆＃39;，＆＃ 39; 2017-11-27 11：39：10＆＃39;，2017-11-27 11：39：48＆＃39;，＆＃39;停止＆＃39;停止＆＃39;停止＆＃39;停止;，＆＃39; org.springframework.batch.core.JobInterruptedException＆＃39;，＆＃39; 2017-11-27 11：39：48＆＃39;，NULL

请注意，STATUS和EXIT_CODE更新为STOPPED。但它引发了一个例外，org.springframework.batch.core.launch.NoSuchJobException: No job configuration with the name [testJob] was registered at org.springframework.batch.core.configuration.support.MapJobRegistry.getJob(MapJobRegistry.java:66) at org.springframework.batch.core.launch.support.SimpleJobOperator.restart(SimpleJobOperator.java:275) at org.springframework.batch.core.launch.support.SimpleJobOperator$$FastClassBySpringCGLIB$$44ee6049.invoke(<generated>) at org.springframework.cglib.proxy.MethodProxy.invoke(MethodProxy.java:204) at org.springframework.aop.framework.CglibAopProxy$DynamicAdvisedInterceptor.intercept(CglibAopProxy.java:669) at org.springframework.batch.core.launch.support.SimpleJobOperator$$EnhancerBySpringCGLIB$$318ff269.restart(<generated>) at com.test.mypackage.batch.dao.BatchJobDaoImpl.restartJobExecution(BatchJobDaoImpl.java:62)。

当我尝试使用executionId重新启动相同的作业时，它无法启动并提供相同的异常（如上所示）。

我的代码很简单，

@Autowired
private DataSource dataSource;
@Autowired
private JobOperator jobOperator;
@Override
public Long stopRunningExecution(Long executionId) throws NoSuchJobExecutionException, JobExecutionNotRunningException {
    jobOperator.stop(executionId);
    return executionId;
}
@Override
public Long restartJobExecution(long executionId) throws JobParametersInvalidException, JobRestartException, JobInstanceAlreadyCompleteException, NoSuchJobExecutionException, NoSuchJobException {
    return jobOperator.restart(executionId);
}

这里有什么问题？

我遇到了类似的错误但是能够解决问题。

由于您尚未定义JobRegistry，因此问题正在发生。如果您定义JobRegistry并将其添加到JobOperator Bean，则不会发生上述异常。

例如：

@Bean
public JobRegistry jobRegistry() {
    return new MapJobRegistry();
}

@Bean
public JobRegistryBeanPostProcessor jobRegistryBeanPostProcessor() {
    JobRegistryBeanPostProcessor jobRegistryBeanPostProcessor = new JobRegistryBeanPostProcessor();
    jobRegistryBeanPostProcessor.setJobRegistry(jobRegistry());
    return jobRegistryBeanPostProcessor;
}

@Bean
public JobOperator jobOperator() {
    SimpleJobOperator jobOperator = new SimpleJobOperator();
    jobOperator.setJobExplorer(getJobExplorer());
    jobOperator.setJobRepository(getJobRepository());
    jobOperator.setJobLauncher(getJobLauncher());
    jobOperator.setJobRegistry(jobRegistry());

    return jobOperator;
}

Spring引导JobOperator.stop（executionId）和JobOperator.restart（executionId）行为
