SSM项目，在web.xml中配置监听器，项目就报404，求大佬帮忙看看。怎么解决？

Question

刚开始的时候，可以正常访问页面，然后配了监听器，再访问就报404，将监听器注释掉又可以正常访问了，网上试了很多方法都不行
这个是web.xml配置信息

  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

</web-app>

这个是文件结构

求大佬帮忙看看咋回事，感谢！

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:spring-config.xml
    </param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

我觉得问题在/WEB-INF这里，路径你最好注意一下
