Assuming all dependencies are there and all other configurations you just need to add the following to your web.xml. 假设所有依赖项都存在，并且所有其他配置都只需将以下内容添加到web.xml中。 I also recommend you read the java ee 7 tutorials and use Netbeans since you are just beginning. 我还建议您阅读Java ee 7教程，并开始使用Netbeans。

 <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>*.xthml</url-pattern>
  </servlet-mapping>
