JSF 标记 (xHTML) 在浏览器上未呈现为 HTML

JSF tags (xHTML) are not rendered as HTML on browser

我正在尝试使用 spring 启动来执行 JSF Primefaces HTML 页工作正常。

但是 xHTML 页面没有呈现为 HTML。如果我在浏览器上按 F12,我会看到 JSF 标签。

我看过: JSF returns blank/unparsed page with plain/raw XHTML/XML/EL source instead of rendered HTML output

最后一个不太确定:

"Multiple JSF implementations have been loaded"

在我的库中,我看到“Maven:org.glassfish.jaxb:txw2:2.3.3”和“Maven:org.glassfish:jakarta.el:3.0.3”以及tomcat。我没有添加任何一个,而且我无法从 IntelliJ IDE 的项目结构中删除它们: 这是我的 pom 文件

我什至重新创建了项目,以防我有一些隐藏的错误配置。

如果您不知道答案,但可以向我指出一个很好的教程,介绍如何设置它,甚至如何跟踪渲染。那会很棒!!!

将此添加到您的模板

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets">

这是给你的 webpage.xhtml

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
                xmlns:h="http://xmlns.jcp.org/jsf/html"
                xmlns:f="http://xmlns.jcp.org/jsf/core"
                xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
                template="/templates/WebPageTemplate.xhtml">

也尝试更改路径 template="/WEB-INF/templates/WebPageTemplate.xhtml"

不知道这样能不能解决你的问题,可能是多种因素造成的。

所以我最终删除了 WEB-INF 并使用了 JoinFaces 4.3 这是一个 github 样例代码:
