    public ApiResponse<CommentDTO> insertComment(@RequestBody CommentDTO commentDTO) throws Exception{
        CommentDTO dto = commentService.insertComment(commentDTO);
        return new ApiResponse(true, "success to post comment in board id " + commentDTO.getId());
    }

CommentDAO.java

int insertComment(CommentDTO commentDTO);

CommentService.java

public CommentDTO insertComment(CommentDTO commentDTO) throws Exception {
        commentDTO.setWriteDate(LocalDate.now());
        commentDTO.setWriteTime(LocalTime.now());

        int insertRowCount = commentDAO.insertComment(commentDTO);
        if (insertRowCount > 0){
            return commentDTO;
        }else {
            throw new Exception("failed to insert comment data");
        }
    }

        insert into comment (id, author, content,writeDate,writeTime)
        values (#{id},#{author},#{content},#{writeDate},#{writeTime})
    </insert>
