客户端jsp请求服务器端Action，还传参

<%@ 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action属性接收参数<a href="user/User_add?name=a&age=8">添加用户</a>
  </body>
</html>

服务器端接收参数，Action中参数最好和客户端jsp请求的参数保持一致，也可以不一致，但是set方法必须要保持一致

package com.lbx.action;

import com.opensymphony.xwork2.ActionSupport;

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

}
