1、POST項目

01. Spring Initalizr

https://start.spring.io/

02.プロジェクト設定

resources/application.properties, server.port = 8090

Package : controller

Class : PostApiController

03.プロジェクト作成

@RequestBody

クライアントから送信JSON形式のHTTP BodyコンテンツをJavaオブジェクトに変換する方法

@RequestBody受信データはSpring管理のMessageConverterの1つであるMappingJackson 2 HttpMessageConverterによりJavaオブジェクト

に変換される.

-1. post()

PostApiController.java

package com.example.post.controller;

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Map;

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

    @PostMapping("/post")
    public void post(@RequestBody Map<String, Object> requestData){

        requestData.forEach((key, value) -> {
            System.out.println("key : " + key);
            System.out.println("value : " + value);
        });

    }
}

-2.dtoの作成

オブジェクトは

を使用しやすい.

Package : dto

Class : PostRequestDto

PostRequestDto.java

package com.example.post.dto;

public class PostRequestDto {
    private String account;
    private String email;
    private String address;
    private String password;

    public String getAccount() {
        return account;
    }

    public void setAccount(String account) {
        this.account = account;
    }

    public String getEmail() {
        return email;
    }

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

    public String getAddress() {
        return address;
    }

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

    public String getPassword() {
        return password;
    }

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

    @Override
    public String toString() {
        return "PostRequestDto{" +
                "account='" + account + '\'' +
                ", email='" + email + '\'' +
                ", address='" + address + '\'' +
                ", password='" + password + '\'' +
                '}';
    }
}

-3.Object Wrapper(JavaがCamelエンクロージャであり、Json転送がSnakeエンクロージャである場合)

JavaがCamelエンクロージャ、Json転送がSnakeエンクロージャの場合

PostRequestDto.java

package com.example.post.dto;

public class PostRequestDto {
    private String account;
    private String email;
    private String address;
    private String password;
    private String phoneNumber; // phone_number

    public String getPhoneNumber() {
        return phoneNumber;
    }

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

    public String getAccount() {
        return account;
    }

    public void setAccount(String account) {
        this.account = account;
    }

    public String getEmail() {
        return email;
    }

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

    public String getAddress() {
        return address;
    }

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

    public String getPassword() {
        return password;
    }

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

    @Override
    public String toString() {
        return "PostRequestDto{" +
                "account='" + account + '\'' +
                ", email='" + email + '\'' +
                ", address='" + address + '\'' +
                ", password='" + password + '\'' +
                ", phoneNumber='" + phoneNumber + '\'' +
                '}';
    }
}

ソリューション

@JsonProperty(鍵が送信されました)

オブジェクトのJSONを変換するときに鍵の名前を開発者に必要な名前に設定する方法

Jacksonライブラリ

をダウンロードするには

PostRequestDto.java

package com.example.post.dto;

import com.fasterxml.jackson.annotation.JsonProperty;

public class PostRequestDto {
    private String account;
    private String email;
    private String address;
    private String password;
    @JsonProperty("phone_number")
    private String phoneNumber; // phone_number

    public String getPhoneNumber() {
        return phoneNumber;
    }

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

    public String getAccount() {
        return account;
    }

    public void setAccount(String account) {
        this.account = account;
    }

    public String getEmail() {
        return email;
    }

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

    public String getAddress() {
        return address;
    }

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

    public String getPassword() {
        return password;
    }

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

    @Override
    public String toString() {
        return "PostRequestDto{" +
                "account='" + account + '\'' +
                ", email='" + email + '\'' +
                ", address='" + address + '\'' +
                ", password='" + password + '\'' +
                ", phoneNumber='" + phoneNumber + '\'' +
                '}';
    }
}
