搭建SSH框架关于配置过滤器的问题

Question

在web.xml文件中加入的过滤器代码：
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter><filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

把过滤器代码去掉就能正常运行tomcat，该加的包都加了，就是不知道怎么回事，纠结很久了，求各位高手帮忙...

这个是我web.xml中写的所有代码：<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">


<!--struts过滤器-->
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter><filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>


  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
   
</web-app>这是struts.xml中的代码（还没添加东西）：<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundastion//DTD Struts Configuration 2.0//EN"
    "Http://Struts.apache.org/dtds/struts-2.0.dtd">
 
其他都没写的，刚刚才开始搭建框架。

Answer 2

是spring的监听么？
是不是这个：
  <listener>
   <listener-class>
   org.springframework.web.context.ContextLoaderListener
   </listener-class>
  </listener>这个加了也一样报错....

Answer 3

.是因为Hibernate和struts2引入的包产生冲突啦，去把xerces.jar移除

Answer 4

  不要听qiaowan19900712瞎扯  spring 和strut2没有直接的关系 你的错误在与struts.xml配置文件 
 配置文件中没有<struts></struts>标签 你加上这个就可以了  加在你原有的配置文件下
