SpringMVC-- submit the form

AbstractCommandController used today to make a sample submission form

(1) First, set up a User.java

package com.zk.domain;

import java.util.Date;

public class User {
	private Integer id;
	private String name;
	private String age;
	private String birthday;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getAge() {
		return age;
	}
	public void setAge(String age) {
		this.age = age;
	}
	public String getBirthday() {
		return birthday;
	}
	public void setBirthday(String birthday) {
		this.birthday = birthday;
	}
}

(2) The second step, implemented ToAddController.java, jump to add.jsp,

package com.zk.UserController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class ToAddController implements Controller{

	public ModelAndView handleRequest(HttpServletRequest request,
			HttpServletResponse response) throws Exception {
		// TODO Auto-generated method stub
		ModelAndView mv=new ModelAndView();
		mv.setViewName("add");
		return mv;
	}
}

(3) a third step to achieve CommandController.java

package com.zk.UserController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractCommandController;

import com.zk.domain.User;

//从页面接受参数，封装javaBean的User对象
public class CommandController extends AbstractCommandController{
	//指定把参数封装到那个对象。
	public CommandController(){
		this.setCommandClass(User.class);
	}
	@Override
	protected ModelAndView handle(HttpServletRequest request,
			HttpServletResponse response, Object command, BindException errors)
			Exception {throws
		// TODO Auto-generated method stub
		// the value of a command object is encapsulated 
		the User User = (the User) Command; 
		
		ModelAndView Music Videos new new ModelAndView = (); 
		// set Models 
		mv.addObject ( "User", User); 
		// Returns the specified interface view 
		mv.setViewName ( "index "); 
		return Music Videos; 
	} 
}

　(4) a fourth step, the configuration SpringMVC.xml

<?xml version="1.0" encoding="UTF-8"?>

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

     	 <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
     	 <bean class="org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter"></bean>
         <!-- 命令对象 -->

         <!-- 跳转到Add页面 -->
         <bean id="/toAdd.do" class="com.zk.UserController.ToAddController"></bean>  
         <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <property name="prefix" value="/WEB-INF/jsp/"></property>
         <property name="suffix" value=".jsp"></property>
         </bean>
         
</beans>

(5) two interfaces jsp

add.jsp

<%@ 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 'add.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>
  <form action="${pageContext.request.contextPath }/command.do">
   Id：<input type="text" name="id"  id="id"/><br>
   name：<input type="text" name="name" id="name"/><br>
   age：<input type="text" name="age" id="age"/><br>
   birthday：<input type="text" name="birthday" id="birthday"/><br>
  <input type="submit" value="提交" />
  </form>
  </body>
</html>

　　index.jsp

<%@ 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="Content-Type" content="text/html;charset=utf-8" />
	<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>
  <!-- ${hello } --> 
  <h1>${user.name}||${user.id}||${user.age}||${user.birthday}</h1> 
  </body>
</html>

　　Results are as follows:
