Question

通常我的jsf页面是这样的：

  <ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:c="http://java.sun.com/jstl/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui"
template="/WEB-INF/jsf/template.xhtml">

<ui:define name="content">  
    <!-- Content Header -->
    <section class="content-header">

    </section>

    <!-- Main content -->
    <section class="content">
        <h:form>    
            <div>
            <div>
            <div>
                <div>
                    <div >
                            <h:outputText value="Hello World!"/>
                    </div>
                </div>
              </div>
            </div>
          </div>
        </h:form>
    </section>
</ui:define>

正如您所注意到的，我有一个template.xhtml，我在每个jsf页面上导入。下面是我的template.xhtml。

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:p="http://primefaces.org/ui">

<f:view>
<h:head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8" />
    <meta http-equiv="Pragma" content="no-cache"/>
    <meta http-equiv="Expires" content="-1"/>
    <h:outputScript library="primefaces" name="jquery/jquery.js" />

    <link type="text/css" rel="stylesheet" href="#{request.contextPath}/css/jsfdefault.css" />

</h:head>
<h:body>
    <div class="outer-container">
        <div class="inner-container">
            <div class="main" style="min-height: 500px">
                <div style="width:100%;border: none;">
                    <ui:include src="/jsf/menu.xhtml"></ui:include>
                </div>
                <div class="content" style="width: 100%; margin-top:-8px;">
                    <ui:insert name="content">
                    </ui:insert>
                </div>
                <div class="clearer"></div>
            </div>
        </div>
    </div>
</h:body>
</f:view>
</html>

现在我想修改我的template.xhtml。我将检查是否为role = Professor，我将调用特定模板（templateForProfessor.xhtml），如果是role = student，我将调用另一个模板（templateForStudent.xhtml）。我不知道在哪里放置if条件。很高兴，如果你能提供样品。

templateForProfessor.xhtml
