// TODO Auto-generated method stub
boolean isWriteSuccess = false;
Connection con = getConnection();
BoardDAO boardDAO = BoardDAO.getInstance();
boardDAO.setConnection(con);
int insertCount = boardDAO.insertBoard(boardBean);
if(insertCount > 0){
commit(con);
isWriteSuccess = true;
}
else{
rollback(con);
}
close(con);
return isWriteSuccess;
}
}
📌게시판 목록 List 처리하는 비즈니스 로직

// TODO Auto-generated method stub
int listCount = 0;
Connection con = getConnection();
BoardDAO boardDAO = BoardDAO.getInstance();
boardDAO.setConnection(con);
listCount = boardDAO.selectListCount(); //DB에서 총 게시판 글의 개수를 반환받음
close(con);

public BoardBean getBoard(int board_num) throws Exception{
// TODO Auto-generated method stub
BoardBean board = null;
Connection con = getConnection();
BoardDAO boardDAO = BoardDAO.getInstance();
boardDAO.setConnection(con);
//조회수 증가 update 작업의 트랜잭션 처리해주는 부분
int updateCount = boardDAO.updateReadCount(board_num);

}
public boolean modifyBoard(BoardBean board) throws Exception {
//글 수정 작업을 처리하는 메소드
boolean isModifySuccess = false;
Connection con = getConnection();
BoardDAO boardDAO = BoardDAO.getInstance();
boardDAO.setConnection(con);
int updateCount = boardDAO.updateBoard(board);
//트랜잭션 처리하는 부분
if(updateCount > 0){
commit(con);
isModifySuccess=true;
}
else{
rollback(con);
}
close(con);
return isModifySuccess;
}
}
📌글 삭제 처리하는 비즈니스 로직

// 글 삭제 요청을 처리하는 메소드
boolean isRemoveSuccess = false;
Connection con = getConnection();
BoardDAO boardDAO = BoardDAO.getInstance();
boardDAO.setConnection(con);
int deleteCount = boardDAO.deleteBoard(board_num);
//트랜잭션 처리하는 부분
if(deleteCount > 0){
commit(con);
isRemoveSuccess=true;
}
else{
rollback(con);
}
close(con);
return isRemoveSuccess;
}
}
