		首先在 Struts2官网上下载 struts2的 包 网址 ：http://struts.apache.org/download.cgi#struts221
 
用这个Full Distribution:
 
struts-2.3.8.-all.zip (76mb) [PGP] [MD5]
解压以后找到 lib里的jar 文件： 主要用 以下几个：
 
 

 
 
把这几个包 导入   你的web网站下的WEB-INF\lib中   ；      Struts部署完成：
 
 
下面开始使用    新建一个  webproject,   包含以下几项：

 
 
首先更改web.xml  文件
 
[java]  
<?xml version="1.0" encoding="UTF-8"?>  
<web-app version="2.5"   
    xmlns="http://java.sun.com/xml/ns/javaee"   
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  
  <welcome-file-list>  
    <welcome-file>index.jsp</welcome-file>  
  </welcome-file-list>  
    
    
  <!-- 定义struts2的核心Filter -->  
    
  <filter>  
    
  <filter-name>struts2</filter-name>  
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  
    
    
  </filter>  
    
  <!-- 让Struts2的核心Filter拦截所有请求 -->  
    
    
    
  <filter-mapping>  
    
  <filter-name>struts2</filter-name>  
  <url-pattern>/*</url-pattern>  
    
  </filter-mapping>  
    
    
    
    
    
</web-app>
