PUT, DELETE, Response내려주기 실습

오늘 공부한 내용은 저번시간에 이어서 put방식과 delete방식, Response내려주기에 대해 실습해 보았다.

우선 put방식에 대해 작성해보겠다. 우선 저번시간에 계속 보던 사진을 가져오겠다.

PutApiController

package com.example.put;

import com.example.put.dto.PostRequestDto;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/api")
public class PutApiController {

    @PutMapping("/put")
    public PostRequestDto put(@RequestBody PostRequestDto requestDto) {
        System.out.println(requestDto);
        return requestDto;
    }
}

PostRequestDto

package com.example.put.dto;

import com.fasterxml.jackson.databind.PropertyNamingStrategy;
import com.fasterxml.jackson.databind.annotation.JsonNaming;

import java.util.List;

@JsonNaming(value = PropertyNamingStrategy.SnakeCaseStrategy.class)
public class PostRequestDto {

    private String name;
    private int age;
    private List<CarDto> carList;

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public List<CarDto> getCarList() {
        return carList;
    }

    public void setCarList(List<CarDto> carList) {
        this.carList = carList;
    }

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

CarDto

package com.example.put.dto;

import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.databind.annotation.JsonNaming;

public class CarDto {
    private String name;

    @JsonProperty("car_number")
    private String carNumber;

    public String getName() {
        return name;
    }

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

    public String getCarNumber() {
        return carNumber;
    }

    public void setCarNumber(String carNumber) {
        this.carNumber = carNumber;
    }

    @Override
    public String toString() {
        return "CarDto{" +
                "name='" + name + '\'' +
                ", carNumber='" + carNumber + '\'' +
                '}';
    }
}

put방식 테스트 및 결과화면

다음으로는 delete방식에 대해서 작성하겠다.

DeletApiController

package com.example.delete.controller;


import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/api")
public class DeletApiController {
    @DeleteMapping("/delete/{userId}")
    public void delete(@PathVariable String userId, @RequestParam String account) {
        System.out.println(userId);
        System.out.println(account);
    }
}

delete방식 테스트 및 결과화면

다음 으로는 Response내려주기에 대해 작성하겠다.

ApiController

package com.example.reponse.controller;

import com.example.reponse.dto.User;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/api")
public class ApiController {

    // TEXT
    @GetMapping("/text")
    public String text(@RequestParam String account) {
        return account;
    }

    //JSON
    @PostMapping("/json")
    public User json(@RequestBody User user) {
        return user;
    }

    @PutMapping("/put")
    public ResponseEntity<User> put(@RequestBody User user) {
        return ResponseEntity.status(HttpStatus.CREATED).body(user);
    }
}

PageController

package com.example.reponse.controller;

import com.example.reponse.dto.User;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/api")
public class ApiController {

// TEXT
@GetMapping("/text")
public String text(@RequestParam String account) {
return account;
}

//JSON
@PostMapping("/json")
public User json(@RequestBody User user) {
return user;
}

@PutMapping("/put")
public ResponseEntity<User> put(@RequestBody User user) {
return ResponseEntity.status(HttpStatus.CREATED).body(user);
}
}

User

package com.example.reponse.dto;

import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.databind.PropertyNamingStrategy;
import com.fasterxml.jackson.databind.annotation.JsonNaming;

@JsonNaming(value = PropertyNamingStrategy.SnakeCaseStrategy.class)
public class User {
    private String name;
    private int age;
    private String phoneNumber;
    private String address;

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getPhoneNumber() {
        return phoneNumber;
    }

    public void setPhoneNumber(String phoneNumber) {
        this.phoneNumber = phoneNumber;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

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

이상으로 오늘 공부한 내용에 대해 작성했다. 내일은 쉬는날이니 쉬고 오겠다 ㅎㅎ

그럼 배위 ~~
