在数据流服务器中运行时出现spring cloud task taskLifecycleListener错误

Question

我实现了 spring 云任务示例中给出的示例批处理作业示例。 其中使用的 spring 引导版本是 2.0.1.RELEASE。 由于我必须移植另一份工作，因此我必须执行 spring 云任务，我想找到兼容的最旧版本。 使用 1.3.2.RELEASE 作为 spring-boot 版本创建的批处理作业 jar 成功运行。 但是当我在将它添加为应用程序后从 spring 云数据流的 UI 运行它时，我收到以下错误：

它的主要任务是没有在给定的数据库中注册。 因此，当我遇到此 Invalid TaskexecutionID 问题时，我将数据库凭据传递给 Dataflow 服务器，并在启动任务时传递了相同的 [DB details]。 通常他们都应该在接收器中使用数据库凭据。 最后，所有 TASK 执行都记录在所提供的数据库中的 TaskID、执行开始时间、执行结束时间等。
