Question

我要整合我的JSP文件，这是我写的代码：

<%  UtilisateurAction useraction = new UtilisateurAction();
    String statut = useraction.Connect(); %>

<c:if test=<%"ADMIN".equals(statut);%>>

<%@ include file="../menu/menu.jsp"%>
</c:if> 


<c:if test=<% "SECR".equals(statut);%>>

<%@ include file="../menu/menuother.jsp"%>
</c:if>

它不起作用，我不知道为什么我在控制台中出现此错误：

Answer 1

修改：忘记了test=

中的c:if

要使用<c:if>，您必须拥有范围变量。当前请求的属性，应用程序上下文的会话各自的范围是请求，会话和应用程序。

您可以轻松地将变量放在页面上下文中（仅对当前jsp有效，而@include包含的其他内容有效，但<jsp:include>不包含）：

<%
...
String statut = useraction.Connect();
pageContext.setAttribute("statut", statut);
%>
<c:if test="${statut == 'ADMIN'}">
...
</c:if>

在我的JSP文件中集成<c：if> </c：if>
