Spring @Scheduler正在执行两次。我正在使用spring security，如果我删除了上下文参数弹簧安全性不起作用

Question

我在我的应用程序中使用spring Scheduler和spring security。如果spring-servlet.xml文件在上下文参数中分配，则spring安全性正常，但Spring Scheduler执行两次。 的安全context.xml中

正如M.Deinum在评论中告诉你的那样，你正在双重加载根上下文。

Here您可以阅读有关mvc context / root context的更多信息。网中有更多关于它的信息

您必须创建一个新的config.xml，让它命名为应用程序上下文或您喜欢的任何其他名称。现在你必须使用spring-servlet.xml并将几乎所有内容移动到新的配置文件中，因此这两个文件都是这样的：
