1.修改或者添加对象
2.多添件查询时候也会遇到
springMvc能够根据属性自动的封装pojo的对象并且支持关联的对象：大致的原理是在传入后台的时候把前台的属性和对象封装成json的形式传入后台，后台根据传入的对象，把Json的形式转换为对象进行处理
具体使用：
-1.地址实体类：包含省份和城市俩个属性
package com.atguigu.springmvc.entity; public class Adress { private String privence; private String city; public String getPrivence() { return privence; } public void setPrivence(String privence) { this.privence = privence; } public String getCity() { return city; } public void setCity(String city) { this.city = city; } @Override public String toString() { return "Adress [privence=" + privence + ", city=" + city + ", getPrivence()=" + getPrivence() + ", getCity()=" + getCity() + ", getClass()=" + getClass() + ", hashCode()=" + hashCode() + ", toString()=" + super.toString() + "]"; } }
-2.创建用户实体：包含用户名，年龄和关联对象地址
package com.atguigu.springmvc.entity; public class User { private String name; private String age; private Adress adress; 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 Adress getAdress() { return adress; } public void setAdress(Adress adress) { this.adress = adress; } @Override public String toString() { return "User [name=" + name + ", age=" + age + "]"; } }
-3.在页面创建表单，包含用户信息
<form action="springmvc/testPojo" method="post"> name:<input type="text" name="name" value=""/> age:<input type="text" name="age" value=""/> city:<input type="text" name="adress.city" value=""/> <input type="submit" value="提交PUT"/> </form>
-4.在controller中进行处理
@RequestMapping(value="/testPojo") public String testPojo(User user){ return SUCCESS; }
