# Spring WEB MVC_03버전_04 게시판 서비스 계층 구현

## BoardService 인터페이스 생성

src/main/java > kr.inflean.service 우 클릭 > New > interface > BoardService 이름으로 생성

package kr.inflearn.service;

import java.util.List;

import kr.inflearn.model.BoardVO;

public interface BoardService {
	public List<BoardVO> getList();		// 게시물 리스트 가져오기
	public void register(BoardVO board);	// 게시물 등록
	public BoardVO get(int bno);		// 게시물 상세보기
	public int remove(int bno);			// 게시물 삭제
	public int modify(BoardVO board);	// 게시물 수정
}

## BoardServiceImpl 생성

구현 클래스 생성
src/main/java > kr.inflean.service 우 클릭 > New > class > BoardServiceImpl 이름으로 생성

package kr.inflearn.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import kr.inflearn.mapper.BoardMapper;
import kr.inflearn.model.BoardVO;

@Service
public class BoardServiceImpl implements BoardService {
	
	@Autowired
	private BoardMapper mapper;		// DI (의존성 주입)
	
	@Override
	public List<BoardVO> getList() {
		return mapper.getList();
	}

	@Override
	public void register(BoardVO board) {
		mapper.insert(board);
	}

	@Override
	public BoardVO get(int bno) {
		return mapper.read(bno);
	}

	@Override
	public int remove(int bno) {
		return mapper.delete(bno);
	}

	@Override
	public int modify(BoardVO board) {
		return mapper.update(board);
	}

	
}

## root-context

root-context에 아래 component-scan 추가.

<context:component-scan base-package="kr.inflearn.service" />

# Spring WEB MVC_03버전_05 게시판 웹 계층 구현

## BoardController

게시물 리스트 작업

package kr.inflearn.web;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import kr.inflearn.model.BoardVO;
import kr.inflearn.service.BoardService;

@Controller
public class BoardController {

	@Autowired
	private BoardService service;
	
	@RequestMapping("/list.do")
	public String list(Model model) {
		List<BoardVO> list = service.getList();		
		model.addAttribute("list", list);
		return "boardList";
	}
	
}

## servlet-context 수정

설정되어 있는 prefix views > board로 변경

<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <beans:property name="prefix" value="/WEB-INF/board/" />
  <beans:property name="suffix" value=".jsp" />
</beans:bean>

## web.xml

요청 mapping 변경 기존 / > *.do 로 변경

<servlet-mapping>
  <servlet-name>appServlet</servlet-name>
  <url-pattern>*.do</url-pattern>
</servlet-mapping>

## boardList.jsp 생성

프로젝트 > src > main > webapp > WEB-INF > board 우 클릭 > New > JSP File > boardList.jsp 생성

## BoardVO

기존 indate 타입을 String > Date로 변경

package kr.inflearn.model;

import java.util.Date;

public class BoardVO {
	private int idx;
	private String title;
	private String contents;
	private int count;
	private String writer;

	public void setTitle(String title) {

	public Date getIndate() {

	public void setIndate(Date indate) {
		this.indate = indate;
	}	
}

## 글쓰기 기능 작업

### boardList.jsp

fmt taglib 추가 후 fmt사용하여 표시되는 데이터 형식 변경

</body>
</html>

### BoardController

@RequestMapping(value="/register.do", method=RequestMethod.GET)

-> value : 넘어오는 요청 경로
-> method : GET, POST 방식 설정

동일한 url이더라도 GET, POST 방식에 따른 처리 분류

@RequestMapping(value="/register.do", method=RequestMethod.GET)
public String registerGET() {
	return "register";			// 게시물 등록 화면.(register.jsp)
}

@RequestMapping(value="/register.do", method=RequestMethod.POST)
public String registerPOST() {			// 게시물 등록
	return "redirect:/list.do";		// 등록 후 게시물 보기로 이동.
}


=> @GetMapping("/register.do")
=> @PostMapping("/register.do")
등의 방법으로도 가능.
