我正在尝试在使用由子模板组成的模板的网页上应用一些CSS。我已经从primefaces中提取了一个模板,并尝试将其分解为2个子模板:commonFooter.xhtml和commonHeader.xhtml。然后,我将它们组装在template.xhtml中,我想在我的页面中使用此template.xhtml。
但是,我没有成功(在本教程https://www.mkyong.com/jsf2/jsf-2-templating-with-facelets-example/之后)。
时,这是预期的结果这是代码:

编辑: 更准确地说,css的路径在这里并不重要,因为它可以在模板为一体时起作用。我认为的问题是,将模板分解为两个单独的实体,然后进行组装,已经破坏了primefaces的外观。
答案 0 :(得分:2)
感谢另一个教程,我找到了使用jsf的标签composition include等方法的方法。我没有很好地使用它们
首先,您需要创建简单的templateFooter.xhtml和templateHeader.xhtml,其后没有html标签,但带有ui:composition标签:
<ui:composition
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:p="http://primefaces.org/ui">
<p:layoutUnit id="top" position="north" size="50">
<p:menubar>
<p:submenu label="Satisfact'IT" icon="ui-icon-document">
<p:submenu label="New" icon="ui-icon-contact">
<p:menuitem value="Project" url="#" />
<p:menuitem value="Other" url="#" />
</p:submenu>
<p:menuitem value="Open" url="#" />
<p:menuitem value="Quit" url="#" />
</p:submenu>
<p:submenu label="Edit" icon="ui-icon-pencil">
<p:menuitem value="Undo" url="#" icon="ui-icon-arrowreturnthick-1-w"></p:menuitem>
<p:menuitem value="Redo" url="#" icon="ui-icon-arrowreturnthick-1-e"></p:menuitem>
</p:submenu>
<p:submenu label="Help" icon="ui-icon-help">
<p:menuitem value="Contents" url="#" />
<p:submenu label="Search" icon="ui-icon-search">
<p:submenu label="Text">
<p:menuitem value="Workspace" url="#" />
</p:submenu>
<p:menuitem value="File" url="#" />
</p:submenu>
</p:submenu>
</p:menubar>
</p:layoutUnit>
</ui:composition>
然后,我们需要创建一个页面template.xhtml,它将使用我们的模板XXXXX.xhtml。该页面需要有一个html标记,因为它将被您的页面使用,并被用户直接看到。因此,您需要使用标签ui:include(它将导入您的templateXXX.xhtml)到标签ui:insert中。您将拥有类似的东西:
<!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:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui"
>
<h:head>
<h:outputStylesheet library="css" name="/showcase.css" />
<h:outputStylesheet library="css" name="/sh.css" />
<style type="text/css">
.ui-layout-north {
z-index:20 !important;
overflow:visible !important;;
}
.ui-layout-north .ui-layout-unit-content {
overflow:visible !important;
}
body {
background-color: #FFFFFF;
}
</style>
</h:head>
<h:body>
<p:layout fullPage="true" >
<ui:insert name="header" >
<ui:include src="commonHeader.xhtml" />
</ui:insert>
<ui:insert name="footer" >
<ui:include src="commonFooter.xhtml" />
</ui:insert>
</p:layout>
<script language="javascript" src="resources/js/sh.js"></script>
<script language="javascript">
SyntaxHighlighter.all();
</script>
</h:body>
</html>
然后调用您的页面作为示例index.xhtml只需编写:
<ui:composition template="WEB-INF/templates/template.xhtml"
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:p="http://primefaces.org/ui"
/>
当我在index.xhtml中时,我还没有找到轻松更改它的方法,但是我会让您保持更新!
