应用程序不呈现“PrimeFaces”组件

Question

我的 JSF 应用程序不呈现“PrimeFaces 组件”。我看过很多关于这些问题的主题，但没有一个对我有帮助。

这是我的手工艺品：

当我从浏览器访问页面时，“primefaces”组件不显示。

Primefaces 3.4.2 不兼容 JSF 2.2。将 jsf-impl 和 jsf-api 更改为使用 2.1 版，并将 web.xml 更改为使用 2.5 版 dtd。

在 pom.xml 中更改 JSF 版本：

    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-api</artifactId>
        <version>2.1.19</version>
    </dependency>

    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-impl</artifactId>
        <version>2.1.19</version>
    </dependency>

将web.xml更新到2.5版本并开启JSF开发模式

<?xml version="1.0" encoding="ISO-8859-1"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee  http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">
