Spring batch Spring批处理异常：org.springframework.batch.core.launch.NoSuchJobException:未注册名为[]的作业配置

当使用jobOperator.stop（id）停止正在运行的作业时，或者当我想使用jobOperator.restart（id）重新启动它时，我会看到此异常。 我不知道为什么MapJobRegistry是空的。。。我漏了一步吗？
我使用了来自的完整示例再现了这个问题

JobOperator

需要一个

JobLocator

来定位要重新启动、停止等的作业。这个

JobLocator

（通常是

MapJobRegistry

）应使用已知作业填充，并且应手动或通过向应用程序上下文添加作业来完成

---

这里的参考文档对此进行了解释：。

我只是添加了一个JobRegistryBeanPostProcessor并将其设置为jobRegistry

   @Autowired
   JobRegistry jobRegistry;

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

如果有帮助，请接受我的答案（你的答案似乎是基于我的）：。谢谢。
