我是春季批量和春季云数据流的新手。 我修改了spring-batch的示例quickstart项目，它现在写在本地MSSQL数据库上：当我使用java -jar运行它时它工作正常。 我现在尝试将其部署到Spring Cloud Data Flow的本地实例，将其作为任务从仪表板导入并尝试运行：它给了我这个错误：

当部署为Stream时，同一个弹出批处理的uber-jar工作：我缺少什么？

感谢回购。
要在SCDF中运行Spring Batch作业，您必须使应用程序适应Spring Cloud Task programming model。请使用Spring Cloud Task和Spring Cloud Data Flow批处理作业样本作为参考。
除非应用程序适应此模型，否则将不会在SCDF中运行。
另一件事。批处理作业只能作为SCDF中的任务运行，并且不能在流中使用。
