JSTL 문법으로 바꿔보기

1️⃣

<%
  PageDTO pageDTO = 
       (PageDTO)request.getAttribute("pageDTO");
// PageDTO에 저장된 4개의 데이터중에서  List만 얻고 출력하기
  List<BoardDTO> list = pageDTO.getList();
%>

 

<c:set var="pageDTO" value="${pageDTO}" />
<c:set var="list" value="${pageDTO.list}" />

<%
  for(BoardDTO dto: list){
	 int num = dto.getNum();
	 String title = dto.getTitle();
	 String author = dto.getAuthor();
	 String writeday = dto.getWriteday();
%>   
   <tr>
    <td><%= num %></td>
    <td><a href="retrieve?num=<%= num %>"><%= title %></a></td>
    <td><%= author %></td>

    <td><%= dto.getReadcnt() %></td>   
    <td><button data-num="<%= num %>">삭제</button></td>   
   </tr>
