1、程序目录如下

2、controller：

package com.controller;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import com.model.User;

@Controller
public class RegisterController {

	@RequestMapping(value="/register",method=RequestMethod.GET)
	public ModelAndView register(){
		User user=new User();
		//user.setHoppies(new String[]{"看书","看电影","玩游戏","垃板胡","画画"});
		user.setGender(0);	//设定默认值
		ModelAndView modelAndView=new ModelAndView("register","command",user);//带参重定向
		return modelAndView;
	}
	
	@RequestMapping(value="getUserInfo",method=RequestMethod.POST)
	public String getInfo(@ModelAttribute("SpringWeb")User user,Model model){
		model.addAttribute("id",user.getId());
		model.addAttribute("userName",user.getUserName());
		model.addAttribute("password",user.getPassword());
		model.addAttribute("gender",user.getGender());
		model.addAttribute("hoppies",user.getHoppies());
		model.addAttribute("country",user.getCountry());
		model.addAttribute("remark",user.getRemark());
		return "show";
	}
	
	@ModelAttribute("countriesList")    //映射列表属性名，给视图中的列表赋值
	public Map<String,String> getCountryList(){
		Map<String,String> countriesList=new HashMap<String,String>();
		countriesList.put("US","America");
		countriesList.put("CN","China");
		countriesList.put("JP","Japan");

		return countriesList;	
	}
	
	@ModelAttribute("hoppiesList")
	public List<String> getHoppyList(){
		List<String> hoppies=new ArrayList<String>();
		hoppies.add("看书");
		hoppies.add("电影");
		hoppies.add("玩游戏");
		hoppies.add("垃板胡");
		hoppies.add("画画");
		return hoppies;
	}
}

3、User

package com.model;

public class User {
	private String id;
	private String userName;
	private String password;
	private int gender;
	private String[] hoppies;
	private String country;
	private String remark;
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;

	public String getRemark() {
		return remark;
	}
	public void setRemark(String remark) {
		this.remark = remark;

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <display-name>springMVC_register</display-name>
  
  	<!-- 配置编码过滤器，解决post请求中文乱码 -->
  	<filter>
		<filter-name>CharacterEncodingFilter</filter-name>	
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>	
		<init-param>	
			<param-name>encoding</param-name>

		</init-param>	
	</filter>	
	<filter-mapping>

	</servlet>
	
	<servlet-mapping>
		<servlet-name>spring</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
</web-app>

5、spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"

        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
        
        <context:component-scan base-package="com.controller"/>
        
        <mvc:annotation-driven/>
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        	<property name="prefix" value="/jsp/"/>
        	<property name="suffix" value=".jsp"/>
        </bean>
        
 </beans>

6、register.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>   
    <title>My JSP 'register.jsp' starting page</title>
  </head>
  
  <body>
    <form:form action="/springMVC_register/getUserInfo" method="post">
    	<table>
    		<caption>User Register</caption>
    		<tr>
    			<td><form:hidden path="id" value="1001"/></td>
    		</tr>
    		<tr>
    			<td><form:label path="userName">用户名</form:label></td>
    			<td><form:input path="userName"/></td>
    		</tr>
    		<tr>
    			<td><form:label path="password">密码</form:label></td>
    			<td><form:password path="password"/></td>
    		</tr>
    		<tr>
    			<td><form:label path="gender">性别</form:label></td>
    			<td>
    				<form:radiobutton path="gender" label="男" value="0"/>
    				<form:radiobutton path="gender" label="女" value="1"/>
    			</td>
    		</tr>
    		<tr>
    			<td><form:label path="hoppies">爱好</form:label></td>

    		<tr>
    			<td><form:label path="country">国籍</form:label></td>
    			<td>
    				<form:select path="country">
    					<form:option label="请选择——" value="none"/>
    					<form:options items="${countriesList}"/>
    				</form:select>
    			</td>
    		</tr>
    		<tr>
    			<td><form:label path="remark">备注</form:label></td>
    			<td><form:textarea path="remark" cols="30" rows="3"></form:textarea></td>
    		</tr>
    		<tr>
    			<td><input type="reset" value="reset"/></td>
    			<td><input type="submit" value="submit"/></td>
    		</tr>
    	</table>
    </form:form>
  </body>
</html>

7、show.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 'show.jsp' starting page</title>

  </head>
  
  <body>
    <table>
    	<tr><td>id:</td><td>${id}</td></tr>
    	<tr><td>userName:</td><td>${userName}</td></tr>
    	<tr><td>password:</td><td>${password}</td></tr>
    	<tr><td>gender</td><td>${(gender==0?'男':'女')}</td></tr>
    	<tr><td>hoppies:</td><td>
			<%
				String[] hoppies=(String[])request.getAttribute("hoppies");
				for(String hoppy: hoppies){
					out.println(hoppy);
				}
			 %>
		</td></tr>
    	<tr><td>country:</td><td>${country}</td></tr>
    	<tr><td>remark:</td><td>${remark}</td></tr>
    </table>
  </body>
</html>

结果
