我有一个 spring 批处理管理应用程序，其中 META-INF/spring/jobs/ 文件夹中有作业 xml。

作业初始化失败并出现以下错误..

如果我将作业文件夹更改为“bootstrap”……应用程序可以工作……但是作业没有被注册……有没有人遇到过这样的问题。

我的理解是每个工作都有不同的应用程序上下文。但例外是我在“根”上下文中做它

Caused by: org.springframework.context.ApplicationContextException: Cannot reinitialize with different application context: current one is [Root WebApplicationContext: startup date [Mon Jul 28 19:08:01 GMT+05:30 2014]; root of context hierarchy], passed-in one is [ResourceXmlApplicationContext:file:/Users/thrinath.d/abc/alliances/alliances/alliances-batch/target/alliances-batch/WEB-INF/classes/META-INF/spring/batch/jobs/alliances-campaign-retry-process.xml]
