java - Spring @Scheduler 执行了两次。我正在使用 spring security，如果我删除上下文参数 spring security 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 security 工作正常，但 spring Scheduler 执行两次。安全上下文.xml

安全工作正常，但调度程序执行两次，为什么，我不明白。请帮助我。

正如 M.Deinum 在评论中告诉你的那样，你陷入了根上下文的双重加载。

Here您可以阅读有关 mvc 上下文/根上下文的更多信息。网上有更多相关信息

您必须创建一个新的 config.xml，我们将其命名为 application-context 或您喜欢的任何其他名称。现在，您必须获取 spring-servlet.xml 并将几乎所有内容移至新的配置文件，因此这两个文件将如下所示:
