integrating log4j in spring

Configure log4j for spring in a Web application
The practice of spring is to use a servlet Listener to write the absolute path of root to the system variable when the Web container is started, so that the log4j configuration file can be ${myappfuse.root} To represent the system variables that have just been set up: Log4j.appender.logfile.file=${myappfuse.root}/logs/mylog.log
The configuration statements in Web.xml are as follows:

<context-param> 
 <param-name>webAppRootKey</param-name> 
 <param-value> myappfuse.root</param-value> 
</context-param>
<context-param> 
 <param-name> Log4jconfiglocation</param-name> 
 <param-value>/web-inf/classes/log4j.properties</ param-value>
</context-param>
<listener> 
 <listener-class> org.springframework.web.util.log4jconfiglistener</listener-class>
</listener> 
<!-- A listener is configured here, and servlet:-->
<!-- 
<servlet>
 <servlet-name>log4j</can also be configured servlet-name>
 <servlet-class>
 org.springframework.web.util.Log4jConfigServlet
 </ servlet-class>
 <load-on-startup>1</load-on-startup>
 </servlet>
