myeclipse中的项目使用log4j问题

myeclipse中的项目实际地址是D:\Myeclipse10\***\WebRoot\，发布到tomcat的地址是D:\apache-tomcat-6.0.41\webapps\***\，这样在使用log4j生成日志文件的时候报错：严重: Exception sending context initialized event to listener instance of class org.springframework.web.util.Log4jConfigListenerjava.lang.IllegalStateException: Web app root system property already set to different value: 'webapp.root' = [D:\Myeclipse10\***\WebRoot\] instead of [D:\apache-tomcat-6.0.41\webapps\***\] - Choose unique values for the 'webAppRootKey' context-param in your web.xml files!

这是web.xml
<context-param> <param-name>log4jConfigLocation</param-name> <param-value>/WEB-INF/classes/log4j.properties</param-value> </context-param><!-- <context-param> --><!-- <param-name>webAppRootKey</param-name> --><!-- <param-value>wxyms.root</param-value>log4j的配置文件里可以用${wxyms.root}来表示刚刚设进去的系统变量 --><!-- </context-param> --> <!-- Listener log4jConfigLocation --> <listener> <listener-class> org.springframework.web.util.Log4jConfigListener </listener-class> </listener>
这该怎么解决！！！

Answer 1

<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:config/log4j.properties</param-value>
</context-param>
把log4j.properties放到resources目录中的config（新建一个）目录下试试

追问

试过了，不行，是监听器报的吧
