十一、请求响应-请求：简单参数和实体参数（简单实体参数与复杂实体参数）

请求响应概述

postman介绍

获取简单参数-springboot方式

代码：springboot方式接收简单参数

//springboot方式接收简单参数
    @RequestMapping("/simpleParam")
    public String simpleParam(@RequestParam(value = "name") String username, Integer age){
        System.out.println(username+" :"+age);
        return "OK";
    }

获取简单参数总结

实体参数-简单实体对象

代码: 简单实体参数

//简单实体参数
    @RequestMapping("/simplePojo")
    public String simplePojo(User user){
        System.out.println(user);
        return "OK";
    }

实体参数-复杂实体对象

代码: 复杂实体参数

 //复杂实体参数
    @RequestMapping("/complexPojo")
    public String complexPojo(User user){
        System.out.println(user);
        return "OK";
    }

实体参数总结

完整代码：

RequestController类

package com.itheima.Controller;

import com.itheima.pojo.User;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class RequestController {
    //springboot方式接收简单参数
    @RequestMapping("/simpleParam")
    public String simpleParam(@RequestParam(value = "name") String username, Integer age){
        System.out.println(username+" :"+age);
        return "OK";
    }
    //简单实体参数
    @RequestMapping("/simplePojo")
    public String simplePojo(User user){
        System.out.println(user);
        return "OK";
    }
    //复杂实体参数
    @RequestMapping("/complexPojo")
    public String complexPojo(User user){
        System.out.println(user);
        return "OK";
    }
}

Address类

package com.itheima.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;
    }

    @Override
    public String toString() {
        return "Address{" +
                "province='" + province + '\'' +
                ", city='" + city + '\'' +
                '}';
    }
}

User类

package com.itheima.pojo;
public class User {
    private String name;
    private Integer age;
    private Address address;
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    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;
    }

    @Override
    public String toString() {
        return "User{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", address=" + address +
                '}';
    }
}

结果

结果一：简单参数

结果二：简单实体参数

结果三：复杂实体参数
