Question

我实现了春季云任务样本中给出的批处理样本示例。其中使用的spring boot版本是2.0.1.RELEASE。由于我必须移植其他工作，因此我必须执行春季云任务，因此我想找到兼容的最旧版本。用1.3.2.RELEASE作为spring-boot版本创建的用于批处理作业的jar成功运行。但是，当我将其添加为应用程序后从spring cloud数据流的UI运行它时，出现以下错误：

大部分Task任务未在给定数据库中注册。因此，当我收到无效的TaskexecutionID问题时，我将数据库凭据传递给了Dataflow服务器，并在启动任务时传递了相同的[DB details]。通常，它们两者都应使用DB凭据存储。最终，所有的TASK执行都被记录在提供的数据库中，并带有TaskID，执行开始时间，执行结束时间等。

任务启动taskTimestmp2 --arguments“ --spring.datasource.url = jdbc：mysql：// localhost：3306 / mydb --spring.datasource.username = root --spring.datasource.driver-class-name = org.mariadb.jdbc.Driver”
