本文解决使用Servlet3.0注解创建Servlet时，与传统web.xml配置产生的冲突问题，通过移除多余的注解配置并重新启动Tomcat，解决了Servlet命名重复导致的异常。

同时匹配到 相同的 url-pattern  ,原因自动生成的 Servlet 3.0 Annotations

去掉代码中的 “  /**
 * Servlet implementation class UserExit
 */
@WebServlet("/UserExit")”


重新启动ｔｏｍｃａｔ　即可

It seems that you have mixed annotation-based and web.xml-based configuration.


I doubt that you created a Servlet using the "Create Servlet" wizard which creates web.xml entry with url-pattern and then , added a @WebServlet annotation which duplicates anything you may put in the web.xml.

tomcat启动错误：The servlets named X and Y are both mapped to the url-pattern [/Z] which is not permitted，首先想到的是肯定部署代码或者项目配置文件的事，怀疑有可能是jar包出错了，果不其然，在项目的WebContent\WEB-INF\lib发现了servlet-api.jar 果然删除再次部署。

原因总结： 1、在web.xml中或者用annotation配置了同一个url-pattern映射， 属于重复配置； 2、做项目的过程中遇到这种情况，最开始使用annotation配置servlet，后来因为还要加一些其他配置就统一改到web.xml中去配置servlet了。用maven命令打包后部署，总是报如上的错误，查了很久终于发现在webapp/WEB-INF/classes目录下有一些
