Spring-批处理到 Spring 云数据流中的 spring 任务
Spring-batch to spring task in Spring cloud data flow
我是 spring-batch 和 spring 云数据流的新手。
我修改了 spring-batch 的示例快速启动项目，它现在写入本地 MSSQL 数据库：当我 运行 使用 java -jar 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：

相同的 spring-batch uber-jar 在部署为 Stream 时工作：我缺少什么？
感谢回购。
要在 SCDF 中 运行 Spring 批处理作业，您必须将应用程序调整为 Spring Cloud Task programming model. Please use the Spring Cloud Task and Spring Cloud Data Flow 批处理作业示例作为参考。
除非应用程序适应此模型，否则它不会 运行 在 SCDF 中。
还有一件事。批处理作业只能 运行 作为 SCDF 中的任务，并且 不能 在流中使用。
