1) com.face.home.springboot.web.dto/ReviewboardRequestDto.java

package com.face.home.springboot.web.dto;

import com.face.home.springboot.domain.reviewboard.ReviewBoard;
import lombok.Builder;
import lombok.Getter;
import lombok.NoArgsConstructor;

@Getter
@NoArgsConstructor
public class ReviewboardRequestDto {

    private String title;
    private String content;
    private String author;

    @Builder
    public ReviewboardRequestDto(String title, String content, String author) {
        this.title = title;
        this.content = content;
        this.author = author;
    }

    public ReviewBoard toEntity() {
        return ReviewBoard.builder().title(title).content(content).author(author).build();
    }

}

- Entity 클래스(Reviewboard.java)와 유사하지만 Entity 클래스를 Request/Response 클래스로 사용해서 안되기 때문에 dto 추가 생성

- Entity 클래스는 데이터베이스와 맞닿은 핵심 클래스로 테이블이 생성되고 스키마가 변경됨

 

2) com.face.home.springboot.service.reviewboard/ReviewboardService.java

package com.face.home.springboot.service.reviewboard;

import com.face.home.springboot.domain.reviewboard.ReviewboardRepository;
import com.face.home.springboot.web.dto.ReviewboardRequestDto;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;


@RequiredArgsConstructor
@Service
public class ReviewboardService {

    private final ReviewboardRepository reviewboardRepository;

    @Transactional
    public Long save(ReviewboardRequestDto reviewboardRequestDto) {
        return reviewboardRepository.save(reviewboardRequestDto.toEntity()).getId();
    }

}

 

3) com.face.home.springboot.web/ReviewboardApiController.java

package com.face.home.springboot.web;

import com.face.home.springboot.service.reviewboard.ReviewboardService;
import com.face.home.springboot.web.dto.ReviewboardRequestDto;
import lombok.RequiredArgsConstructor;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@RequiredArgsConstructor
@RestController
public class ReviewboardApiController {

    private final ReviewboardService reviewboardService;

    @PostMapping("/api/v1/reviewboard")
    public Long save(@RequestBody ReviewboardRequestDto reviewboardRequestDto) {
        return reviewboardService.save(reviewboardRequestDto);
    }

}
