Question

我是JSF和facelets的新手。我正在尝试基于this tutorial创建facelets模板。 common.xhtml不会在header/content/footer.xhtml中显示任何文字。我已经在stackoverflow上阅读了几个与此主题相关的帖子，并根据这些帖子尝试了几个不同的exp，但它们都不起作用。 localhost:8080/AppName/templates/common.xhtml始终是空白页面，但localhost:8080/AppName/templates/header.xhtml正确呈现。

感谢任何帮助。我在这里想念的是什么？

header.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 xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets">
  <body> 
    <ui:composition>
    <h1>Default Header</h1>
    </ui:composition> 
  </body>
</html>

footer.xhtml和content.xhtml类似，因此在此处省略。

common.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 xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core">
<h:head></h:head>
<h:body>
    <div id="header">
        <ui:insert name="header">
            <ui:include src="/templates/header.xhtml" ></ui:include>

我尝试过以下几点 header.xhtml，templates / header.xhtml，./ header.xhtml，＃{request.contextPath} /templates/header.xhtml 但是common.xhtml仍显示空白页面

     </ui:insert>
        <br></br>
    </div>
    <div id="content">
        <ui:insert name="content">
            <ui:include src="/templates/content.xhtml" ></ui:include>
        </ui:insert>
        <br></br>
    </div>
    <div id="footer">
        <ui:insert name="footer">
            <ui:include src="/templates/footer.xhtml" ></ui:include>
        </ui:insert>
        <br></br>
    </div>
</h:body>
</html>

项目文件结构：

WebContent
|->META-INF
|->WEB-INF
|->templates
         |-> common.xhtml
         |-> footer.xhtml
         |-> header.xhtml
         |-> content.xhtml

的web.xml

<?xml version="1.0" encoding="UTF-8"?>
