User.java

package com.bean;import java.io.Serializable;//域对象，实现序列化接口public class User implements Serializable {private String username;private String sex;private Integer age;public User() {super();// TODO Auto-generated constructor stub}public User(String username, String sex, Integer age) {super();this.username = username;this.sex = sex;this.age = age;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}@Overridepublic String toString() {// TODO Auto-generated method stubreturn "User [username=" + username + ", sex=" + sex + ", age=" + age + "]";}}

UserController.java

package com.control;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import com.bean.User;/* *  HelloWorldController是一个基于注解的控制器, *  可以同时处理多个请求动作，并且无须实现任何接口。 *  org.springframework.stereotype.Controller注解用于指示该类是一个控制器 */@Controllerpublic class UserController {@RequestMapping(value="/registerForm",method=RequestMethod.GET)public String registerForm(Model model) {User user=new User("Haige", "男", 20);// model中添加属性command，值是user对象 model.addAttribute("command",user);     return "registerForm";}@RequestMapping(value="/registerForm2",method=RequestMethod.GET) public String registerForm2(Model model) { User user = new User("Haige","男",20); // model中添加属性user，值是user对象        model.addAttribute("user",user);     return "registerForm2"; }}
