[Spring JPA] <include> index.jsp

 

https://intheham.tistory.com/67

include 지시자 및 액션 태그를 활용한 index.jsp

 

 

 

작동 방식이나 jsp 표현 방식은 이전과 같다.

서버 전송 방식이 Servlet 에서 JPA Controller 로 변했을 뿐!

 

 

index.jsp

<table>
	<tr>
		<td colspan="2" style="width:100%; height:30%">
			<%@ include file="header.jsp" %>
		</td>
	</tr> 
	<tr>
		<td style="width:50px; height:60%">
			<c:if test="${sessionScope.type == 1}"> <!-- 구매자 -->
				<%@ include file="cmenu.jsp" %>
			</c:if>
			<c:if test="${sessionScope.type == 2}"> <!-- 판매자 -->
				<%@ include file="smenu.jsp" %>
			</c:if>
		</td>
		<td>
			<c:if test="${not empty bodyview }">
				<jsp:include page="${bodyview }" />
			</c:if>
		</td>
	</tr>
</table>

 

header.jsp

<style>
.t1{
	width:200px;
	height:50px;
}
</style>

<h1>함함 샵</h1>
<c:if test="${not empty sessionScope.loginId}">
	<h3>~ hello ${sessionScope.loginId} ~</h3>
</c:if>

<table>
<tr>
<c:if test="${empty sessionScope.loginId}">
	<td class="t1"><a href="/shopmember/join">회원가입</a></td>
	<td class="t1"><a href="/shopmember/login">로그인</a></td>
</c:if>
<c:if test="${not empty sessionScope.loginId}">

	<td class="t1"><a href="/shopmember/logout">로그아웃</a></td>
	<td class="t1"><a href="/shopmember/out?id=${sessionScope.loginId }">회원탈퇴</a></td>
</c:if>
</tr>
</table>

 

cmenu.jsp

<h3>구매자 메뉴</h3>
<a href="">구매내역</a><br/>
<a href="">상품목록</a>

 

smenu.jsp

<h3>판매자 메뉴</h3>
<a href="">상품등록</a><br/>
<a href="">상품목록</a>

 

ShopmemberController

(1) 모든 메서드의 return 경로를 "index"나 "redirect:/" 로 바꿔준다.

(* @ResponseBody 로 가는 AJAX 를 제외 )

- return "index";    >> 내부에서 요청하는 뷰 경로

- return "redirect:/"    >> 외부에서 요청하는 뷰 경로 (HomeController 에서 매칭함)

@Controller
public class HomeController {
   @RequestMapping("/")  // http://localhost:8081/ (외부 요청)
   public String home() {
      return "index";    // /WEB-INF/views/index.jsp (내부 요청)
   }
}

 

(2) include로 띄울 jsp 경로를 map에 담아 반환한다.

@GetMapping("/join")
public String joinForm(ModelMap map) {
	map.addAttribute("bodyview", "/WEB-INF/views/shopmember/join.jsp");
	return "index";
}
