JSP请求代码，传了参数

<%@ 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>My JSP 'index.jsp' starting page</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>
	使用Domain Model接收参数<a href="user/User_add?user.name=a&user.age=8">添加用户</a>
  </body>
</html>

参看struts,xml代码

<?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>
<constant name="struts.ognl.allowStaticMethodAccess" value="true"></constant>
    <package name="user" namespace="/user" extends="struts-default">
        
        <action name="*_*" class="com.lbx.action.{1}Action" method="{2}">
            <result>/{1}_{2}_success.jsp</result>
            <!-- {0}_success.jsp -->
        </action>
    </package>
    
</struts>

找到相应的Action

package com.lbx.action;

import com.lbx.model.User;
import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport{
	
	private User user;
	
	public String add() {
		System.out.println("name=" + user.getName());
		System.out.println("age=" + user.getAge());
		return SUCCESS;
	}

	public User getUser() {
		return user;
	}

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

UserAction中封装了一个User类

package com.lbx.model;

public class User {
	private String name;
	private int age;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	
}
