1.打开 Eclipse 新建一个 test 项目   Eclipse -> File -> New -> Dynamic Web Project 


2.在 test/WebContent  下面新建一个 user.jsp 文件 

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>

<body>
姓名:<%=request.getAttribute("name") %>
性别:<%=request.getAttribute("gender") %>
月薪:<%=request.getAttribute("salary") %>
爱好:<%=request.getAttribute("interest") %>

<hr>

<form action="user!add" method="post"   >
 	姓名:<input type="text" name="name" />
 	
 	性别:<input type="radio" name="gender" value="1" />男 <input type="radio" name="gender" value="2" />女
 	
 	月薪:
 	<select name="salary">
 		<option value="20000">20000</option>
 		<option value="30000">30000</option>
 		<option value="40000">40000</option>
 		<option value="50000">50000</option>
 	</select>
 	
 	爱好:<input type="checkbox" name="interest" value="唱歌" />唱歌 <input type="checkbox" name="interest" value="篮球" />篮球
 	
 	
 	<input type="submit" name="submit" value="submit" />
 </form>
</body>
</html>



3.在 test/src  下面新建一个 com.test.action.UserAction 类 

package com.test.action;

import javax.servlet.http.HttpServletRequest;

import com.vere.mvc.ServletActionContext;
import com.vere.mvc.util.CParam;

public class UserAction {

	public String execute() {
		
		return "success";
	}
	
	public String add() {
		HttpServletRequest request = ServletActionContext.getRequest();
		
		String name=CParam.getString(request, "name");
		int gender=CParam.getInt(request, "gender");
		long salary=CParam.getLong(request, "salary");
		String interest=CParam.getStrings(request, "interest");

		request.setAttribute("name", name);
		request.setAttribute("gender", gender);
		request.setAttribute("salary", salary);
		request.setAttribute("interest", interest);
		return "success";
	}
}



4.在 test/src/VereMVC.xml  里面配置Action 

<?xml version="1.0" encoding="UTF-8"?>
<VereMVC>
	<constant name="charset"  value="utf-8" />
	<constant name="developMode"  value="true" />
	<constant name="language"  value="en_US" />
	

    <action name="user" class="com.test.action.UserAction">
      <result name="success">/user.jsp</result>
      <result name="add">/user.jsp</result>
    </action>
</VereMVC>



5.在 浏览器地址栏输入 http://localhost:8080/test/user
