JSF / Facelets：无法使用< h：outputStylesheet>识别CSS文件。标签 [英] JSF/Facelets : CSS file is not being recognized using <h:outputStylesheet> tag
问题描述
我正在使用JSF / Facelets项目。我想对我的View XHTML做一些CSS更改，但是当我在我的Tomcat服务器部署我的Web应用程序没有什么发生。我尝试了很多技巧，但我得到了相同的结果。
无论如何，这里是我的styles.css：
body {width：750px; }
#header
{
width：100％;
font-size：36px;
font-weight：bold;
line-height：48px;
background-color：navy;
color：white;
}
#footer
{
width：100％;
font-weight：bold;
background-color：navy;
color：white;
}
这是主要模板Template.html，包括Header.html 和Footer.html，其中我使用标签：
<！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：f =http://java.sun.com/jsf/core
xmlns：h =http://java.sun.com/jsf/html
xmlns：ui =http://java.sun.com/jsf/facelets>
< head>
< h：outputStylesheet name =css / styles.css/>
<！ - 我也试过这个，使用库属性 - >
<！ -
< h：outputStylesheet library =cssname =styles.css/&
- >
< / head>
< h：body>
< h：panelGroup id =pagelayout =block>
< h：panelGroup id =headerlayout =block>
< ui：insert name =header>
< ui：include src =Header.html/>
< / ui：insert>
< / h：panelGroup>
< h：panelGroup id =containerlayout =block>
< h：panelGroup id =contentlayout =block>
< ui：insert name =content> CONTENT< / ui：insert>
< / h：panelGroup>
< / h：panelGroup>
< h：panelGroup id =footerlayout =block>
< ui：insert name =footer>
< ui：include src =Footer.html/>
< / ui：insert>
< / h：panelGroup>
< / h：panelGroup>
< / h：body>
< / html>
$ b
Anf终于这里是我的Main.xhtml，其中包含模板Template.html p>
<？xml version =1.0encoding =UTF-8？&
<！DOCTYPE html PUBLIC - // W3C // DTD XHTML 1.0 Transitional // ENhttp://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">
< ui：composition xmlns =http://www.w3.org/1999/xhtml
xmlns：f =http://java.sun.com/jsf/core
xmlns：h =http://java.sun.com/jsf/html
xmlns：ui =http://java.sun.com/jsf/facelets
xmlns ：a4j =http://richfaces.org/a4j
xmlns：rich =http://richfaces.org/richtemplate =Template.html>
< h：body>
< ui：define name =content>
< h：form>
< h：inputText title =inputText>< / h：inputText>
< h：commandButton value =OK>< / h：commandButton>
< / h：form>
< / ui：define>
< / h：body>
< / ui：composition>先感谢：） 解决方案 < h：outputStylesheet> （and < h：outputScript> ）需要< h：head> ，但你有一个< head> 。
< h：head>
< h：outputStylesheet name =css / styles.css/>
< / h：head>
此外，您需要确保 css / styles.css 文件已被放置在公共web内容的 / resources 子文件夹中。
WebContent
| - resources
| ` - css
| ` - styles.css
：
至于您尝试使用 library 属性，请注意，使用 library =css在此上下文中并不完全正确。另请参阅：什么是JSF资源库for和如何使用？
I'm working on a project using JSF/Facelets. I want to do some CSS changes on my View XHTML, but nothing happen when i deploy my web application in my Tomcat Server. I've tried many tricks but i've got the same result.
Anyway, here's my "styles.css" :
body { width: 750px; }
#header
{
width: 100%;
font-size: 36px;
font-weight: bold;
line-height: 48px;
background-color: navy;
color: white;
}
#footer
{
width: 100%;
font-weight: bold;
background-color: navy;
color: white;
}
And this is the main template "Template.html" including "Header.html" and "Footer.html", where i put my "styles.css" using the tag :
<!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:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<head>
<h:outputStylesheet name="css/styles.css" />
<!-- i've also tried this one, using the "library" attribute -->
<!--
<h:outputStylesheet library="css" name="styles.css" />
-->
</head>
<h:body>
<h:panelGroup id="page" layout="block">
<h:panelGroup id="header" layout="block">
<ui:insert name="header">
<ui:include src="Header.html" />
</ui:insert>
</h:panelGroup>
<h:panelGroup id="container" layout="block">
<h:panelGroup id="content" layout="block">
<ui:insert name="content">CONTENT</ui:insert>
</h:panelGroup>
</h:panelGroup>
<h:panelGroup id="footer" layout="block">
<ui:insert name="footer">
<ui:include src="Footer.html" />
</ui:insert>
</h:panelGroup>
</h:panelGroup>
</h:body>
</html>
Anf finally here's my "Main.xhtml" which include the template "Template.html" :
<?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">
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:a4j="http://richfaces.org/a4j"
xmlns:rich="http://richfaces.org/rich" template="Template.html">
<h:body>
<ui:define name="content">
<h:form>
<h:inputText title="inputText"></h:inputText>
<h:commandButton value="OK"></h:commandButton>
</h:form>
</ui:define>
</h:body>
</ui:composition>
Thanks in advance :)
解决方案 The <h:outputStylesheet> (and <h:outputScript>) requires a <h:head>, but you've there a <head>. Fix it accordingly.
<h:head>
<h:outputStylesheet name="css/styles.css" />
</h:head>
Further, you need to ensure that the css/styles.css file is been placed in the /resources subfolder of the public webcontent.
WebContent
|-- resources
| `-- css
| `-- styles.css
:
As to your attempt to use the library attribute, be careful with this, using library="css" isn't entirely correct in this context. See also: What is the JSF resource library for and how should it be used?
