1) 싱글톤 방식

	}

	@Override

2) 어노테이션을 쓴다면 (지금사용안함)

	@Override
	public List<Board> listAll() throws Exception {
		// TODO Auto-generated method stub
		return dao.selectAll();
	}

	@Override
	public void insert(Board board) throws Exception {
		dao.insert(board);
	}

	@Override
	public read(int bno) throws Exception {

	}

	@Override
