警告：此页面要求使用前缀 pe 声明的 XML 命名空间 http://primefaces.org/ui/extensions 但该命名空间不存在标签库

Question

我正在使用 maven、JSF 2.2、primefaces 7.0、glassfish v4.1.1、adminfaces 管理模板。当我运行项目时，一切正常，除了每次页面呈现某些内容时都会出现警告。

这是我的web.xml

我曾尝试查看类似的问题，但其中 none 解决了我的问题。 adminfaces 管理模板带有其他依赖项，如 primefaces。我假设我使用的 primefaces 依赖项可能与 admin-tamplate 附带的依赖项冲突 The warning appears like this:

Answer 1

出现错误是因为我没有在我的 POM 文件中包含 primefaces 扩展。

 <dependency>
        <groupId>org.primefaces.extensions</groupId>
        <artifactId>primefaces-extensions</artifactId>
        <version>10.0.0</version>
 </dependency>

警告：此页面要求使用前缀 pe 声明的 XML 命名空间 http://primefaces.org/ui/extensions 但该命名空间不存在标签库

Warning: This page calls for XML namespace http://primefaces.org/ui/extensions declared with prefix pe but no taglibrary exists for that namespace
