在web.xml中增加Servlet：log4j

<servlet>

       <servlet-name>log4j</servlet-name>

       <servlet-class>com.wafer.weixin.servlet.Log4JServlet</servlet-class>

       <load-on-startup>1</load-on-startup>//加载该servlet，1代表优先级

    </servlet>

    <servlet-mapping>

       <servlet-name>log4j</servlet-name>

       <url-pattern>/log4j</url-pattern>

</servlet-mapping>
