[Java] 게시판 만들기

자바 교육을 받으며 혼자 매우 아주 베리 간단한 게시판을 만들어 봤다. 

 

 

DataBase : mariaDB

Back-End : Java, JSTL

Front-End : Jsp

Server : Apach Tomcat 9 

 

 

 

구현

index페이지

 

 

 

 

 

로그인 페이지

 

 

 

 

 

 

 

로그인 후 이동된 글 전체보기 페이지

 

 

 

 

 

 

 

 

글 상세보기

 

 

 

 

 

 

 

검색하기 : "제"로 검색

포함된 것도 검색할 수 있게 만들었다. 

 

 

 

 

 

 

 

 

검색하기 : "제목4"로 검색

 

 

 

 

게시물 작성하기

 

 

 

 

 

 

입력하고 등록 누르기

 

 

 

 

 

 

등록버튼을 누르면 전체 목록 페이지로 넘어간다.

게시글이 잘 작성된 걸 볼 수 있다. 

 

 

 

 

 

 

 

 

 

 

 

구조

나중에는 beans는 beans에다가 위치시켰고,

다른 컨트롤러, 서비스, 서블렛은 그 상위 폴더에다 위치시켰다.
