#### 【例】使用method属性实现用户登录与注册 ####

#### 第一步：编写action ####

package com.dwx.actions;
    import com.opensymphony.xwork2.ActionSupport;
    public class userAction extends ActionSupport{
    	private String username;
    	private String password;
    	private String age;
    	private String sex;
    	public String getAge() {
    		return age;
    	}
    	public void setAge(String age) {
    		this.age = age;
    	}
    	public String getSex() {
    		return sex;
    	}
    	public void setSex(String sex) {
    		this.sex = sex;
    	}
    	public String login(){
    		return SUCCESS;
    	}
    	public String regist(){
    		return SUCCESS;
    	}
    	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;
    	}
    }

#### 第二步：配置struts2.xml ####

<?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="user" extends="struts-default" namespace="/">
    		<action name="loginAction" class="com.dwx.actions.userAction" method="login">
    			<result name="success">/success.jsp</result>
    		</action>
    		<action name="registAction" class="com.dwx.actions.userAction" method="regist">
    			<result name="success">/regist_info.jsp</result>
    		</action>
    	</package>
    </struts>

#### 第三步：编写登录页面 ####

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%@ taglib prefix="s" uri="/struts-tags" %>
    <%
    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>用户登录</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">
    	
      <style type="text/css">
      a{text-decoration: none;}
      </style>
      </head> 
      <body>
        <center>
        	<s:form action="loginAction" method="post" name="loginForm">
        		<s:textfield name="username" label="用户名"></s:textfield>
        		<s:password name="password" label="密码"></s:password>
        		<s:submit value="登录"></s:submit>
        		<s:a href="regist.jsp">注册</s:a> 
        	</s:form>
        </center>
      </body>
    </html>

#### 第四步：编写注册页面 ####

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%@ taglib prefix="s" uri="/struts-tags" %>
    <%
    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>注册页面</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">
    	
    
      </head>
      
      <body>
        <center>
        	<s:form action="registAction" method="post">
        		<s:textfield name="username" label="用户名"></s:textfield>
        		<s:password name="password" label="密码"></s:password>
        		<s:textfield name="age" label="年龄"></s:textfield>
        		<s:radio name="sex" label="性别" list="{'男','女' }"  value="男"></s:radio>
        		<s:submit value="注册"></s:submit>
        	</s:form>
        </center>
      </body>
    </html>

#### 第五步：编写登录成功页面 ####

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%@ taglib prefix="s" uri="/struts-tags" %>
    <%
    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>登录成功</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">
    	
      </head>  
      <body>
      <h3 align="center">登录成功</h3>
      <hr>
      <center>
       		欢迎:<s:property value="username" />
      </center>
      </body>
    </html>

#### 第六步：编写注册成功页面 ####

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%@ taglib prefix="s" uri="/struts-tags" %>
    <%
    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>注册信息</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">
    	
      </head>
      
      <body>
      <h3 align="center">注册信息</h3>
      <hr>
      <center>
      		用户名:<s:property value="username" /><br>
     		密码：<s:property value="password" /><br>
     		年龄:<s:property value="age"/><br>
     		性别:<s:property value="sex"/><br>
      </center> 		
      </body>
    </html>
