DispatcherServlet.noHandlerFound No mapping found for HTTP request找不到映射文件遇到的问题

//出现找不到spring配置文件

严重 [http-nio-80-exec-1] org.springframework.web.servlet.FrameworkServlet.initServletBean Context initialization failed
 org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [spring-mvc.xml]; nested exception is java.io.FileNotFoundException: class path resource [spring-mvc.xml] cannot be opened because it does not exist
	at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:343)
	at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:303)

输入路径之后找不到路径

警告 [http-nio-80-exec-13] org.springframework.web.servlet.DispatcherServlet.noHandlerFound No mapping found for HTTP request with URI [/account/operate] in DispatcherServlet with name 'DispatcherServlet'

做过一些尝试 ：在web.xml配置中修改对spring配置的加载
谁能想到上面的一堆错误全来自于

    
      
          jstl
          jstl
          1.2
      
      
          taglibs
          standard
          1.1.2
      

 我把这些注释掉，重启tomcat
  再添加上，重启tomcat就又可以了？？？卧槽卧槽卧槽！！！
