BoardController

 

빈 티켓을 만들어줌 

else if(command.equals("/BoardDelete.bo")) {
    System.out.println(" C : /BoardDelete.bo호출 ");
    System.out.println("C : [패턴1] DB 사용 x, view 페이지 이동");

    forward = new ActionForward();
    forward.setPath("./board/deleteForm.jsp");
    forward.setRedirect(false);

}else if(command.equals("/BoardDeleteAction.bo")) {
    System.out.println(" C : /BoardDeleteAction.bo 호출");
    System.out.println(" C : [패턴2] DB 사용 O , 페이지 이동 (화면전환)");
}

//BoardDeleteAction() 객체
	action = new BoardDeleteAction();
	
	try {
		forward = action.execute(request, response);
	} catch (Exception e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

실제 이동 해야 하는 주소는 "./board/deleteForm.jsp" 이므로, 가상 주소는 false 

주소는 안바뀌면서 화면만 보여지는 forwarding을 해야 한다. 

 

 

 

 

 

 

BoardDeleteAction 객체 생성

package com.itwillbs.action;
import java.io.PrintWriter;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.itwillbs.db.BoardDAO;
import com.itwillbs.db.BoardDTO;


public class BoardDeleteAction implements Action {

	@Override
	public ActionForward execute(HttpServletRequest request, HttpServletResponse response) throws Exception {
		System.out.println(" D : ***********************************");
		System.out.println(" D : BoardDeleteAction_execute()호출");
		
		//페이지 전달 정보 저장 (bno, pass, pageNum)
		
		int bno = Integer.parseInt(request.getParameter("bno"));
		String pass = request.getParameter("pass");
		String pageNum = request.getParameter("pageNum");
		
		//BoardDAO 객체 생성
		BoardDAO dao = new BoardDAO();
		
		int result = dao.deleteBoard(bno, pass);
		
		//결과에 따른 페이지 이동 (JS)
		response.setContentType("text/html; charset=UTF-8");
		
		//통로
		PrintWriter out = response.getWriter();
		
		//제어문 통해서 동작
		if(result ==1 ) {
			out.print("<script>");
			out.print(" alert('게시판 글 삭제 완료!');");
			out.print(" location.href='./BoardList.bo?pageNum="+pageNum+"';");
			out.print("</script>");
			out.close();
			
			return null;
		}else if(result == 0) {
			out.print("<script>");
			out.print(" alert('비밀번호 오류!');");
			out.print("history.back();");
			out.print("</script>");
			out.close();
			
			return null;

			out.print("history.back();");
			out.print("</script>");
			out.close();
			
			
			return null;
		}
		//request 영역에 저장
