WEB.XML文件中已经添加了：
<servlet-mapping>
     <servlet-name>jsp</servlet-name>
     <url-pattern>*.jspx</url-pattern>
</servlet-mapping>

<welcome-file-list>
     <welcome-file>index.html</welcome-file>
     <welcome-file>index.htm</welcome-file>
     <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<servlet-mapping>
     <servlet-name>jsp</servlet-name>
     <url-pattern>*.jsp</url-pattern>
</servlet-mapping>
