1、首先下载Struts2GA版本，GA的全称是General Availability。

使用Struts2必须的包：core、xwork、freemarker、ognl。

2、配置web.xml文件
<filter>
<filter-name>struts2filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
filter-class>
filter>
<filter-mapping>
<filter-name>struts2filter-name>
<url-pattern>/*url-pattern>
filter-mapping>

3、建立JSP

<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags" %>
>
<html>
<head>
<title>struts2 testDemotitle>

head>

<body>
<s:form action="login.action" method="post">
<s:textfield key="username" name="user.username"/>
<s:password key="password" name="user.password" />
<s:submit key="submit" />
s:form>
body>
html>

4、建立Action
package cc.dynasoft.action;

import cc.dynasoft.vo.User;

public class LoginAction
{
private User user;

public User getUser()
{
return user;
}

public void setUser(User user)
{
this.user = user;
}

public String execute() throws Exception
{
if(user.getUsername().equals("chenshuang") && user.getPassword().equals("chenshuang"))
{
return "success";
}
else
{
return "error";
}
}
}
User.java
package cc.dynasoft.vo;

public class User
{
private String username;
private String password;

public String getUsername()
{
return username;
}
public void setUsername(String username)
{
this.username = username;
}
public String getPassword()
{
return password;
}
public void setPassword(String password)
{
this.password = password;
}
}

5、配置struts.xml
xml version="1.0" encoding="UTF-8" ?>
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<package name="login" extends="struts-default">
<action name="login" class="cc.dynasoft.action.LoginAction">
<result name="success">/welcome.jspresult>
<result name="error">/login.jspresult>
action>
package>
struts>
