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>
