你能分享一下你的web.xml文件吗？

它必须具有JSF的servlet定义和映射。

下面的元素必须存在于您的web.xml中：

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>

</servlet>

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

请注意* .xhtml表示Faces Servlet将处理扩展名为.xhtml的所有JSF文件，您必须将其更改为您定义的扩展名。

希望这会对你有所帮助。
