비즈니스 계층 구현

비즈니스 계층(서비스 계층)

• 고객의 요구사항을 반영하는 계층
• 업무의 단위로 설계(트랜잭션의 단위)
• 여러 개의 Mapper나 DAO를 사용하는 경우가 존재
• xxxService 형태로 작성

서비스 패키지 설정

• 인터페이스와 클래스를 설정하고, root-context.xml에 등록

package org.zerock.service;

import java.util.List;

import org.zerock.domain.BoardVO;

public interface BoardService { // 고객과 의사소통하는 용어로 작성

	public void register(BoardVO boardVO);
	
	public BoardVO get(Long bno);
	
	public int modify(BoardVO boardVO);
	
	public int remove(Long bno);
	
	public List<BoardVO> getList();

프레젠테이션(웹) 계층의 CRUD 구현

웹 계층의 구현

• 웹 계층에서 가정 먼저 설계하는 것은 URI의 설계
• 기준? → 와이어프레임, 스토리보드

Task	URL	Method	Parameter	From	URL 이동
전체 목록	/board/list	get
등록처리	/board/register	post	모든 항목	입력화면 필요	이동
조회	/board/get	get	bno=n
삭제 처리	/board/remove	post	bno	입력화면 필요
수정 처리	/board/modify	post	모든 항목	입력화면 필요	이동

 

작업의 순서

• 목록페이지 : 모든 진입 경로인 동시에 입력을 가는 링크
• 등록 입력/처리 : 게시물 등록 및 처리, 처리 후 이동
• 조회 : 목록 페이지에서 특정 게시물로 이동
• 수정/삭제 : 조회 페이지에서 수정/삭제 선택해 처리

Controller 목록 처리

• 게시물(BoardVO)의 목록을 Model에 담아서 전달
• Model 전달 당시에는 없는데 화면에서 추가적인 데이터가 필요한 경우

package org.zerock.controller;

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

@Controller
@Log4j

@RequiredArgsConstructor
public class BoardController {

	@GetMapping("/list")
	public void list() {
		log.info("BoardController list()");
	}
	
	
}
