JSTL & EL


1. JSTL(JSP Standard Tag Library), EL(Expreession Language)


2. JSTL은 사용자 정의 태그를 표준화 시킨 것. JSP 내부에서 JSP 명령을 태그 스타일의 명령으로 표현한 것.


3. jstl.jar, standard.jar 파일 필요.


4. JSTL은 core, format, xml, sql 처리 영역이 있다.

 - core 영역은 변수 처리, 흐름제어, url 처리등을 담당.

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


<c:out value="데이터" /> -> 데이터 출력문


<c:set var="변수이름" value="데이터" /> -> 변수 선언문


<c:if test="조건식"> -> if제어문

//실행문

</c:if>


<c:choose> -> if~else제어문

<c:when test="조건식"> </c:when>

<c:otherwise> </c:otherwise>

</c:choose>


<c:forEach var="변수이름" items="컬렉션데이터">

</c:forEach>


5. EL은 표현식(<%=%>)을 대신하는 효과를 가지며 null 값을 가지는 변수에 대해 좀 더 관대하고, 데이터 형 변환을 자동적으로 해준다.


6. EL은 ${표현식} 형태로 표기.

<=%10%>

-> ELK표기법으로 고치면

${dto.id}
