JSF标签无法呈现 – FacesServlet可能无法正常工作？
我刚刚开始使用JSF 2.0，并且我在一开始就遇到了问题。 不解析JSF标记。
以下是一些细节。 希望有人可以提供帮助，因为没有任何相关的SO问题能够解决我的问题。
为hello.jsp
asd 我在导航到http://localhost:8080/JSFDeneme/pages/hello.jsp
只有明文asd
查看http://localhost:8080/JSFDeneme/pages/hello.jsp
与hello.jsp的内容hello.jsp
asd
web.xml中
JSFDeneme index.html index.htm index.jsp default.html default.htm default.jsp hello.jsp Faces Servlet javax.faces.webapp.FacesServlet 1 Faces Servlet /faces/* /pages/* *.jsf javax.servlet.jsp.jstl.fmt.localizationContext resources.application State saving method: 'client' or 'server' (=default). See JSF Specification 2.5.2 javax.faces.STATE_SAVING_METHOD client This parameter tells MyFaces if javascript code should be allowed in the rendered HTML output. If javascript is allowed, command_link anchors will have javascript code that submits the corresponding form. If javascript is not allowed, the state saving info and nested parameters will be added as url parameters. Default is 'true' org.apache.myfaces.ALLOW_JAVASCRIPT true If true, rendered HTML code will be formatted, so that it is 'human-readable' ie additional line separators and whitespace will be written, that do not influence the HTML code. Default is 'true' org.apache.myfaces.PRETTY_HTML true org.apache.myfaces.DETECT_JAVASCRIPT false If true, a javascript function will be rendered that is able to restore the former vertical scroll on every request. Convenient feature if you have pages with long lists and you do not want the browser page to always jump to the top if you trigger a link or button action that stays on the same page. Default is 'false' org.apache.myfaces.AUTO_SCROLL true org.apache.myfaces.webapp.StartupServletContextListener
faces-config.xml中
我在WEB-INF/lib有什么
- JSF 2.0（Apache Myfaces JSF Core-2.0 API 2.0.2） – Eclipse下载了
- JSTL-API-1.2.jar
- JSTL-IMPL-1.2.jar
- primefaces-3.0jar子
当我重新启动服务器并导航到页面时，Tomcat打印到控制台的内容
似乎没什么奇怪的，也没有提到FacesServlet ？

为hello.jsp
这不是正确的扩展。
从JSF 2.0开始， JSP被弃用并被Facelets取代 。 Facelets是一种基于XML的视图技术，应该用.xhtml文件编写。 但是，您似乎已经在JSP文件中使用了有效的Facelets语法。 您需要做的就是将hello.jsp重命名为hello.xhtml 。
我还建议用单个URL模式*.xhtml替换所有URL模式。
Faces Servlet *.xhtml
这样你就可以通过http：// localhost：8080 / JSFDeneme / hello.xhtml打开它而无需摆弄虚拟URL。
我不确定你读过哪些书籍/教程让你使用JSP扩展。 也许您正在阅读JSF 1.x和JSF 2.x目标教程的混合。 您需要确保您正在阅读JSF 2.x特定教程。 在我们的JSF wiki页面的底部，您可以找到几个JSF 2.x教程链接。
我想，当您调用.jsp URL时，您将通过良好的旧JSP servlet呈现页面（您将/pages/* URL映射到Faces servlet，但JSP扩展映射可能优先）。
您可以尝试将页面重命名为.jsf并调用它吗？
尝试将以下代码放在web.xml中
jsfexample faces javax.faces.webapp.FacesServlet 1 faces *.xhtml
