spring的b/s项目中配置log4j

如果是b/s项目，并且项目中有spring,那使用Log4j是很简单的，在web.xml中配置以下内容即可.

 <context-param>
  <param-name>log4jConfigLocation</param-name>
  <param-value>/WEB-INF/log4j.properties</param-value>
 </context-param>
 <context-param>
  <param-name>log4jRefreshInterval</param-name>
  <param-value>60000</param-value>
 </context-param>

 <listener>
  <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
 </listener>

同时保证/WEB-INF/中有log4j.properties文件。

文件内容：

#FATAL 0
#ERROR 3
#WARN 4
#INFO 6
#DEBUG 7
#log4j.rootLogger = [ level ] , appenderName, appenderName, ?
