D. Spring Framework 게시판 만들기 (코멘트 입력, 출력)-스프링게시판강좌교육

D. Spring Framework 게시판 만들기 (코멘트 입력, 출력)-스프링게시판강좌교육 -유경석

1. 시작하기

- 이번에는 게시판 상세보기(글읽기) 페이지에서 게시글에 커멘트를 입력하고, 입력되어 있는 커멘트를 글을 게시글 조회 시 같이 조회될 수 있는 기능을 추가해 보자.

2. [CommentDTO.java] <---- 만들어야됨.

package com.board.model;

public class CommentDTO {

private String comment_seq;

private String comment_name;

private String comment_comm;

private String seq;

public String getComment_seq() {

return comment_seq;

}

public void setComment_seq(String comment_seq) {

this.comment_seq = comment_seq;

}

public String getComment_name() {

return comment_name;

}

public void setComment_name(String comment_name) {

this.comment_name = comment_name;

}

public String getComment_comm() {

return comment_comm;

}

public void setComment_comm(String comment_comm) {

this.comment_comm = comment_comm;

}

public String getSeq() {

return seq;

}

public void setSeq(String seq) {

this.seq = seq;

}

3. [BoardDAO.java] , [BoardDAOImple.java]
