我在 Eclipse Juno 中使用 Tomcat 7 在 JAVA 7 中创建了一个应用程序。它当时运行良好，但几天后它停止工作。现在，每当我尝试运行该应用程序时，它都会显示以下错误：

Now how can handle these errors. after surfing too much at some place i got a way by adding commons-looging.jar, but it doesnot worked.
现在如何处理这些错误。在某个地方冲浪太多后，我通过添加 commons-looging.jar 获得了一种方法，但它不起作用。

The error message says it all:
错误消息说明了一切：
The servlets named [AdminController] and [muShag.Private.controller.AdminController] are both mapped to the url-pattern [/AdminController] which is not permitted.
名为 [AdminController] 和 [muShag.Private.controller.AdminController] 的 servlet 都映射到不允许的 url-pattern [/AdminController]。
Fix your web.xml or your annotations so that those two servlets are not mapped to the same url-pattern, or so that only one of those servlets is defined.
修复您的 web.xml 或您的注释，以便这两个 servlet 不会映射到相同的 url-pattern，或者只定义这些 servlet 中的一个。
