web.xml中log4j.properties的配置,必须配在Spring的IOC容器启动之前(也就是把这段代码放到Spring的监听器前面)

web.xml:

 <context-param>    <param-name>webAppRootKey</param-name>    <param-value>webApp.root</param-value> </context-param> <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>
