log4j配置

web. 中：   value为你配置文件的路径，写你自己的

<!-- 加载log4j -->
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:properties/log4j.properties</param-value>
    </context-param>
    <listener>
         <listener-class>org.spring work.web.util.Log4jConfigListener</listener-class>
    </listener>

log4j.properties 中，这个我随意配的，可根据你的情况配置，文件夹与空文件我都是提前创建好的，不知道没提前创建是否会自动创建。
