struts2通配符使用

【例】使用通配符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 "regist_info";
	}
	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="user*" class="com.dwx.actions.userAction" method="{1}">
			<result name="success">/success.jsp</result>
			<result name="regist_info">/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">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
  <style type="text/css">
  a{text-decoration: none;}
  </style>
  </head> 
  <body>
    <center>
    	<s:form action="userlogin" 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">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->

  </head>
  
  <body>
    <center>
    	<s:form action="userregist" 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">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
  </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">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
  </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>
