📋 BController.java 🔎 content_view

객체 자체를 보냄. request를 model에 보냄
model.addAttribute("request", request);
"request" : 이름 request :객체

package com.oracle.oMVCBoard.controller;

import javax.servlet.http.HttpServletRequest;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@Controller
public class BController {
	private static final Logger logger = LoggerFactory.getLogger(BController.class);
	
	BCommand command = null;
	
	@RequestMapping("list")
	public String list(Model model) {
		logger.info("list start....");
		
		// 실제 MAPPING 할것 적기
		command = new BListCommand();
		command.execute(model);
		return "list";
	}
	
	@RequestMapping("/content_view")
	public String content_view(HttpServletRequest request, Model model) {
		System.out.println("content_view()");
		
		model.addAttribute("request", request); // "request" : 이름  request:객체
		command = new BContentCommand();
		command.execute(model);
		
		return "content_view";
	}
}

📋 BContentCommand.java

asMap 을 쓰면 model을 map으로 보내줌
request란 이름으로 넘겨줬으므로 request로 부름

(HttpServletRequest) map.get("request");에서 HttpServletRequest으로 캐스팅해준이유 ❓

		HttpServletRequest request = (HttpServletRequest) map.get("request"); 
		String bId = request.getParameter("bId");
		
		BDao dao = new BDao();
		BDto board = dao.contentView(bId);
		
		model.addAttribute("mvc_board", board);

결과 : 조회수 증가 성공

🚩 Update 수정

같은 화면은 하나 더 만들 이유가 없다. 있는 화면 재활용하기

📋 BController.java 🔎 modify

컨트롤러에 추가.

	@RequestMapping(value = "/modify", method = RequestMethod.POST)
	public String modify(HttpServletRequest request, Model model) { //Model에 담아가야하기 때문에
		logger.info("modify Start....");
		model.addAttribute("request", request);
		command = new BModifyCommand();
		command.execute(model);
		
		return "redirect:list";
	}

📋 BModifyCommand.java

String bId = request.getParameter("bId"); 파라메터로 받을수도 있지만
🔺 Dto를 만들어 사용하는것이 권장.

만들면 modify에 밑줄 뜬다. BDao에서 modify를 만들어줘야한다.

package com.oracle.oMVCBoard.command;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.ui.Model;

import com.oracle.oMVCBoard.dao.BDao;
import com.oracle.oMVCBoard.dto.BDto;

public class BContentCommand implements BCommand {

	@Override
	public void execute(Model model) {
		Map<String, Object> map = model.asMap(); //asMap 을 쓰면 model을 map으로 보내줌
		HttpServletRequest request = (HttpServletRequest) map.get("request"); 
		String bId = request.getParameter("bId");
		
		BDao dao = new BDao();
		BDto board = dao.contentView(bId);
		
		model.addAttribute("mvc_board", board);
	}
}

📋 BDao.java 🔎 modify

void modify 만들기.

String bId, String bName, String bTitle, String bContent을 보냈다.
❗ 값 보내는 것은 PK + 수정할 내용들

	public void modify(String bId, String bName, String bTitle, String bContent) {
		Connection conn = null;
		PreparedStatement pstmt = null;
		
		try {
			conn = dataSource.getConnection();
			
			String sql = "update mvc_board set bName=?, bTitle=?, bContent=? where bId=?";
			
			System.out.println("BDao modify sql ->" + sql);
			
			pstmt = conn.prepareStatement(sql);
			
			pstmt.setString(1, bName);
			pstmt.setString(2, bTitle);
			pstmt.setString(3, bContent);
			pstmt.setInt   (4, Integer.parseInt(bId));
				
			int	rn = pstmt.executeUpdate();
	
		} catch (Exception e) {
			System.out.println(e.getMessage());
		} finally  {
			try {
				if(conn != null)  conn.close();
				if(pstmt != null) pstmt.close();
			} catch (Exception e2) {
				e2.printStackTrace();
			}
		}
	}

🚩 Delete 삭제

이전것들 보고 해서 일단은 성공! 😬 안보고는 못해..

📋 BController.java 🔎 delete

컨트롤러에 추가. '@RequestMapping("/delete")'
return "redirect:list"; delete 후에 list로 이동

	@RequestMapping("/delete")
	public String delete(HttpServletRequest request, Model model) { //Model에 담아가야하기 때문에
		System.out.println("delete() Start....");
		model.addAttribute("request", request);
		command = new BDeleteCommand();
		command.execute(model);
		
		return "redirect:list";
	}

📋 BDeleteCommand.java

과제, -> 수업중 시간안에 완성해보기.

1.BDeleteCommand Service 파일 생성
1) model이용 , map 선언
2) request 이용 -> bId 추출
3) dao instance 선언
4) delete method 이용하여 삭제

package com.oracle.oMVCBoard.command;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.ui.Model;

import com.oracle.oMVCBoard.dao.BDao;
import com.oracle.oMVCBoard.dto.BDto;

public class BDeleteCommand implements BCommand {

	@Override
	public void execute(Model model) {
		Map<String, Object> map = model.asMap(); //asMap 을 쓰면 model을 map으로 보내줌
		HttpServletRequest request = (HttpServletRequest) map.get("request"); 
		String bId = request.getParameter("bId");
		
		BDao dao = new BDao();
		BDto board = dao.delete(bId);
		
		model.addAttribute("mvc_board", board);
	}
}

📋 BDao.java

delete를 해서 >> int rn = pstmt.executeUpdate();

	public BDto delete(String bId) {
		BDto dto = null;
		Connection conn = null;
		PreparedStatement pstmt = null;
		System.out.println("BDto delete Start ... ");
		
		try {
			conn = dataSource.getConnection();
			String sql = "delete from mvc_board where bId = ?";
					
			pstmt = conn.prepareStatement(sql);
			pstmt.setString(1, bId);
			int rn = pstmt.executeUpdate();
			
		} catch (Exception e) {
			System.out.println(e.getMessage());
		} finally  {
			try {
				if(conn != null)  conn.close();
				if(pstmt != null) pstmt.close();
			} catch (Exception e2) {
				e2.printStackTrace();
			}
		}
		return dto;
	}

📌📋 HomeController.java 🔎write_view

	@RequestMapping("/write_view")
	public String writeView(Model model) { //Model에 담아가야하기 때문에

📌📋 BController.java 🔎write

DB에서 insert가 된것은 확인이 되었는데 화면에서 오류났다.
😬 return "redirect:list"; 이부분이 빠져서이다. 내용은 넣었는데 이동이 안되어서 오류!

BWriteCommand 에 밑줄뜨면 >> 만들기. BWriteCommand.java

	@PostMapping(value = "/write")
	public String write(HttpServletRequest request, Model model) {

		model.addAttribute("request", request);
		command = new BWriteCommand();

		String bContent = request.getParameter("bContent");
		
		BDao dao = new BDao();
		dao.write(bName, bTitle, bContent);
	}
}

📋 BDao.java 🔎 write

작성하면 write에 밑줄 -> write.java 작성

	public void write(String bName, String bTitle, String bContent) {
