复杂类型的绑定  
1、准备一个复杂对象

package com.test.pojo;
    
    public class User {
    
        private String uname;
        private String pwd;
        private int age;
        private Address address;
    
        public String getUname() {
            return uname;
        }
    
        public void setUname(String uname) {
            this.uname = uname;
        }
    
        public String getPwd() {
            return pwd;
        }
    
        public void setPwd(String pwd) {
            this.pwd = pwd;
        }
    
        public int getAge() {
            return age;
        }
    
        public void setAge(int age) {
            this.age = age;
        }
    
        public Address getAddress() {
            return address;
        }
    
        public void setAddress(Address address) {
            this.address = address;
        }
    
        @Override
        public String toString() {
            return "User{" +
                    "uname='" + uname + '\'' +
                    ", pwd='" + pwd + '\'' +
                    ", age=" + age +
                    ", address=" + address +
                    '}';
        }
    }

package com.test.pojo;
    
    public class Address {
    
        private String province;
    
        private String city;
    
        private String detailAddress;
    
        public String getProvince() {
            return province;
        }
    
        public void setProvince(String province) {
            this.province = province;
        }
    
        public String getCity() {
            return city;
        }
    
        public void setCity(String city) {
            this.city = city;
        }
    
        public String getDetailAddress() {
            return detailAddress;
        }
    
        public void setDetailAddress(String detailAddress) {
            this.detailAddress = detailAddress;
        }
    
        @Override
        public String toString() {
            return "Address{" +
                    "province='" + province + '\'' +
                    ", city='" + city + '\'' +
                    ", detailAddress='" + detailAddress + '\'' +
                    '}';
        }
    }

2、表单中传值的时候，表单控件名称设置为

属性名和表单的控件名一致

子对象中的属性 用 属性名.子对象的属性名

3、控制层接收

@RequestMapping("/user2")
    public class UserController2 {
    
        @RequestMapping("/addUser")
        public String addUser(User user)
        {
            //直接用user对象接收
            System.out.println(user);
    
            return "success";
        }
    }
