更新spring boot 1.2到1.3并将批处理作业添加到spring cloud dataflow任务

我们使用多个批处理作业,这些作业使用spring boot 1.2.0进行配置,并与spring batch admin一起使用 . 我们现在正尝试将这些作业转换为任务,以便我们可以在Spring Cloud 数据流中实现它们 . 为此,我将spring boot从1.2.0更新为1.3.2 . 我添加了@EnableTask注释,之后它将其识别为任务但是当批处理作业运行并且我单击UI上的作业选项卡时,scdf服务器会出现错误,说“运行的Spring批处理应用程序不是任务” . 为此,我还将@EnableBatchProcessing添加到主应用程序中 . 之后我收到以下错误:
