Question

我是Java和JSF的新手，并尝试使用JSF模板<ui:include>和<ui:insert>创建测试页面。因此，我只在页面上获得<ui:insert>个阻止，但不会呈现<ui:include>。有人可以告诉我这里有什么问题吗？这是我的模板main_template.xhtml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html lang="en"
      xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:h="http://xmlns.jcp.org/jsf/html">
    <h:head>
        <title>Title Here</title>
    </h:head>
    <h:body>
        <div id="header">
            <ui:include src="header.xhtml"/>
        </div>
        <div>
            <div id="menu">
                <ui:insert name="menu">Menu string</ui:insert>
            </div>
            <div id="content" >
                <ui:insert name="content">Main Content</ui:insert>
            </div>
        </div>
    </h:body>
</html>

此处index.xhtml：

<ui:composition template="WEB-INF/templates/main_template.xhtml"
     xmlns="http://www.w3.org/1999/xhtml"
     xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
     xmlns:h="http://xmlns.jcp.org/jsf/html">

    <ui:define name="menu">
        <h1>Menu will be here</h1>
    </ui:define>

    <ui:define name="content">
        <h1>New content here</h1>
        <p>Blah blah</p>
    </ui:define>
</ui:composition>

..和header.xhtml：

<ui:composition 
      xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:h="http://xmlns.jcp.org/jsf/html">
    <h2>Header page</h2>
    <p>Include page blah blah lorem ipsum</p>
</ui:composition>

在定义模板文件时，/之前错过了WEB-INF。

<ui:composition 
                template="/WEB-INF/templates/main_template.xhtml"
                xmlns="http://www.w3.org/1999/xhtml"
                xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
                xmlns:h="http://xmlns.jcp.org/jsf/html">
</ui:composition>

JSF <include>在模板</include>中不起作用
