SpringMVC-03 使用POJO作为参数

Spring MVC 会按请求参数名和POJO 属性名进行自动匹配，自动为该对象填充属性值。支持级联属性。如：dept.deptId、dept.address.tel 等

user.java

package com.weixuan.springmvc.handlers;public class User {private String username;private String passwd;private String email;private Integer age;private Address address;public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPasswd() {return passwd;}public void setPasswd(String passwd) {this.passwd = passwd;}public String getEmail() {return email;}public void setEmail(String email) {this.email = email;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}public Address getAddress() {return address;}public void setAddress(Address address) {this.address = address;}@Overridepublic String toString() {return "User [username=" + username + ", passwd=" + passwd + ", email="+ email + ", age=" + age + ", address=" + address + "]";}}

address.java

package com.weixuan.springmvc.handlers;public class Address {private String province;private String Ciry;public String getProvince() {return province;}public void setProvince(String province) {this.province = province;}public String getCiry() {return Ciry;}public void setCiry(String ciry) {Ciry = ciry;}@Overridepublic String toString() {return "Address [province=" + province + ", Ciry=" + Ciry + "]";}}

form表单

<form action="springmvc/TestPojo" method="post">username:<input type="text" name="username" /><br> <br>passwd:<input type="password" name="passwd" /><br> <br>email:<input type="text" name="email" /><br> <br> age:<input type="text" name="age" /><br> <br>ciry:<input type="text" name="address.Ciry"><br> <br>province:<input type="text" name="address.province"><br> <br><input type="submit" value="Submit" /></form>

controller

@RequestMapping("/TestPojo")public String TestPojo(User user) {System.out.println("TestPojo :"+user);return SUCCESS;}
