L08 Bean으로 값(parameter) 전달
2016. 10. 27. 18:20ㆍProgramming/JSP
**배운 것**
1) bean 클래스 사용 선언
<jsp:useBean id="bean" class="com.jsp.bean.Member"/>
2) 값 세팅/찾아오기
<jsp:setProperty property="id" name="member" value="walker1991"/>
<jsp:getProperty property="id" name="member"/>
3) 값 세팅 한꺼번에 다 하기
<jsp:setProperty property="*" name="mem"/>
4) 더 간결하게 값 찾아오기
<h3>${member.email}</h3>
<h3>${member["email"]}</h3>
