 A. Srping Framework 게시판 만들기 (리스트,페이징,검색) , 스프링 게시판 소스, 리스트보기, 스프링공부, Spring학원




1.     시작하기
 
-       이클립스 프로젝트명(Context명)은 onjboard1
-       이클립스 STS Plug-In을 설치 하였으며 MAVEN, MAVEN Plug-In도 설치하였음
-       Spring MVC Project를 작성(프로젝트 이름은 onjboard1)
-       Spring Version은 3.2.3
-       오라클에 접속하여 scott 계정에서 게시판용 테이블 및 데이터 2건 만들자
 
 -- 게시판
-- 게시글번호, 작성자, 비밀번호, 글제목, 글내용, 파일이름, 작성일, 조회수

  filename  varchar2(100)not null,
  regdate   date         default sysdate,
  readcount number(10)   default 0,
  
  constraint b_seq_pk primary key(seq)
);

create sequence sequence_board_seq
start with 1 increment by 1;

-- 댓글
-- 댓글 입력한 게시글 번호, 댓글 깊이, 댓글 출력순서
create table reply(
  reply       varchar2(1000) not null,
  reply_step  number(10) default 0,
  reply_level number(10) default 0,
  constraint reply_seq_fk foreign key(reply) references board02(seq)
);

-- 코멘트
-- 코멘트 입력 번호, 코멘트 작성자, 코멘트 내용, 코멘트 입력된 게시글번호
create table comment_t02(
  comment_seq  varchar2(1000),
  comment_name varchar2(20)   not null,
