SpringMVC(十二) RequestMapping使用POJO作为参数

将一个普通的JAVA类对象作为一个参数传入。

POJO类Address：

package com.tiekui.springmvc.pojo;

public class Address {
    private String province;
    private String city;
    
    
    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;
    }
}

POJO类User:

package com.tiekui.springmvc.pojo;


public class User {
    private String username;
    private String password;
    private String email;
    private int age;
    
    private Address address;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    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 [username=" + username + ", password=" + password + ", email=" + email + ", age=" + age
                + ", address=" + address + "]";
    }
    
}

控制器代码：

package com.tiekui.springmvc.handlers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.tiekui.springmvc.pojo.User;


@Controller
public class RequestPOJO {
    
    @RequestMapping("testRequestPojo")
    public String testRequestPojo(User user) {
        System.out.println(user);
        return "success";
    }
}

视图代码：

    <form action="testRequestPojo">
    username : <input type="username" name="username">
    <br>
    password : <input type="password" name="password">
    <br>
    email : <input type="text" name="email">
    <br>
    age : <input type="text" name="age">
    <br>
    province : <input type="text" name="address.province">
    <br>
    city : <input type="text" name="address.city">
    <br>
    <input type="submit" value="PojoTest">
    </form>
