作为一个初学者，虽然网上有许多Struts2的程序，自己作为一个初学者，写一个简单的Struts2程序，希望各位采纳

第一步：配置web.xml

<?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">
	
<filter>  <!--配置struts2过滤器 -->
	<!--过滤器名称 -->
	<filter-name>struts2</filter-name>
	<!--过滤器类 -->
	<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

<filter-mapping>
	<filter-name>struts2</filter-name>  <!--过滤器名称 -->
	<url-pattern>/*</url-pattern>  <!--过滤器映射 -->
</filter-mapping>

<welcome-file-list>
    <welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>

第二步，配置Struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">  
    
    <struts>
    <!--声明包-->
    	<package name="default" namespace="/" extends="struts-default">
    	<!--定义action -->
    		<action name="login" class="com.aisino.development.login" method="execute">
    		<!--定义处理成功后的映射页面 -->
    			<result name="success">/JSP/success.jsp</result>
    			<result name="fail">/JSP/fail.jsp</result>
    		</action>
    	</package>
    </struts>

第三步，写Action对象

package com.aisino.development;

import com.opensymphony.xwork2.ActionSupport;

public class login extends ActionSupport{
	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;
	}
	
	public String execute() {
		if("admin".equals(this.username) && "123".equals(password)){
			return "success";
		}
		else{
			return "fail";
		}

	}
	
}

第四部，写login.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>登录页面</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
  </head>
  
  <body>
  <center><h2>登录系统</h2>
    <form action="login" method="post">
    	账号：<input type="text" name="username" /><br><br>
    	密码：<input type="password" name="password"/><br><br>
    	<input type="submit" value="提交"/>
    	<input type="reset" value="重写"/>
    </form>
    
		
    </script>
    
  </body>
</html>
