eclipse测试Struts2配置时，控制台报错，浏览器也总是显示404错误。

Question

刚学struts照着书本和网上的很多小例子来测试自己的struts配置的对不对，但是总是遇到404错误

下面是我导入的jar包。（把struts的jar包做成了user Libraries，在工程的build path直接导入的，反正跟直接粘贴在web-inf/lib下结果都一样）

下面是web.xml内容

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>12</display-name>
   <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

这是Struts.xml内容

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
    <package name="default" namespace="/" extends="struts-default">
		<action name="Test" class="com.action.Test">
            <result name="success">/helloworld.jsp</result>
        </action>
    </package>
    <!-- Add packages here -->
</struts>

这是报错信息

。。。。

我在网上找很久解决办法。也都试了。。并没有用。

是我工程就建的不对么？求指点一下，刚开始学就卡住了。。。

Answer 1

你试试把两个<filter-name>struts2</filter-name>里面改为<filter-name>struts</filter-name>

Answer 2

一样，第一个struts的配置弄了两天，还是404错误。我就放弃了。
