是否有可能在JSF 2.1中使用jspx文件扩展名？

Question

我的问题如下。我们的项目最初是用JSF 1.2编写的，文件扩展名为.jspx。现在，当我从JSF 1.2迁移到JSF 2.1时，我遇到了在jspx页面中使用JSF 2.0标签的问题。所以，web.xml：

<context-param>
    <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
    <param-value>.jspx</param-value>
</context-param>

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.html</url-pattern>
</servlet-mapping>

当我尝试使用时，我收到错误：

但是，当我用.jspx或任何其他扩展名替换javax.faces.DEFAULT_SUFFIX文件扩展名和xhtml param时，它可以正常工作。我也试着设置：

 <context-param>
    <param-name>DEFAULT_FACELETS_SUFFIX </param-name>
    <param-value>.jspx</param-value>
</context-param>

<context-param>
    <param-name>FACELETS_SUFFIX_PARAM_NAME</param-name>
    <param-value>.jspx</param-value>
</context-param>

<context-param>
    <param-name>DEFAULT_SUFFIX_PARAM_NAME</param-name>
    <param-value>.jspx</param-value>
</context-param>

<context-param>
    <param-name>FACELETS_VIEW_MAPPINGS_PARAM_NAME</param-name>
    <param-value>.jspx</param-value>
</context-param>

问题 ：我是否需要使用.jspx或xhtml或任何其他扩展来替换jsf扩展名，以便使用所有JSF2功能？
