스프링프레임워크 파일 구조 정리 

그제부터 게시판을 만들고 있었다
선생님의 소스코드를 똑같이 해도 되긴 했지만.
처음부터 다시 구축하고 싶었다.
초기세팅 파일의 기록을 남겨놓고자 한다 🙏

상담게시판으로 진입 시 DB에 저장되어 있는 게시글들을 가져와야 했다.
그리고 가져온 게시글을 화면에 뿌려줘야 하는데 이것을 table형식으로 된 부분으로
적용하여 jsp파일에 대입되도록 해야 했다.

가장 중요한 부분은

이 부분이다
이 문법은 JSTL문법 사용한다는 의미이고 forEach문을 통해 반복문을 진행한다

<!-- jstl 문법을 사용한다 --> 
<%@ taglib  uri="http://java.sun.com/jsp/jstl/core"  prefix="c"%>

상단에 해당 소스를 꼭 적어줘야 한다

내 소스에는 list.title부분에 list.contactNum이 같이 들어가져 있는데
글의 상세 보기를 눌렀을 때 게시글 번호를 알아야 하므로 같이 삽입되도록 진행했다

실행하면 이렇게 나온다

제목을 클릭하면 게시글의 상세로 이동이 가능하다
전체적인 파일은 추후 올리도록 하겠다

곧 마지막 프로젝트를 향해 달라겨가고있다!
슬슬 준비를 해야 할 것 같다
