 JSTL 타임 셋팅

 

 

1. 라이브러리 다운 받기

 

 

mvnrepository.com/artifact/javax.servlet/jstl/1.2

Maven Repository: javax.servlet » jstl » 1.2

먼저 위의 사이트에서 JSTL jar파일을 다운받아 주세요.

 

 

 

2. taglib 지시자 선언

<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

 - java에서 jstl 사용하려면 위 코드 꼭 작성하셔야 합니다!

 

 

 

3. 코드
