log4j输出不到项目相对路径WEB-INF下，求大神帮忙解决

Question

web.xml的配置，按照网上说的，Log4jConfigListener已经放到了spring监听器的前面了，但是还是不能输出到相对路径中。

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

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

        <param-name>log4jRefreshInterval</param-name>
        <param-value>600000</param-value>
