无法在tomcat 8.5和7.0上运行我的Spring MVC项目

标签： java spring spring-mvc

我在运行spring mvc项目时遇到问题，我尝试了在堆栈溢出和其他社区站点上提供的其他解决方案，但仍然无法解决问题，我不知道到底是什么问题，我尝试了哪些选项， 一世。将我的日食版本从火星更改为日食光子 ii。有人告诉我更改jdk版本，因为我仅使用jdk 8.65，而我没有安装其他版本。 iii。我将雄猫服务器从7更改为8.5，仍然收到相同的错误。

以下是我在运行项目时获得的堆栈跟踪。

感谢大家的快速反应，我已经弄清了我面临的问题， 我想有几件事会引起错误，

  1. 我将项目从动态Web项目转换为Maven项目。
  2. 我忘记删除我添加到lib目录中的库了（很可能这是主要问题）
  3. 在我的web.xml文件中，我错误地放置了显示名称标签，该标签应该是servlet标签中的servlet名称。

我当前的web.xml
