在web.xml里添加如下代码

<context-param>     
    <param-name>webAppRootKey</param-name>      
        <param-value>myappfuse.root</param-value> 
    </context-param>
<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/classes/log4j.properties</param-value>
    </context-param>
<context-param>
    <param-name>log4jRefreshInterval</param-name>
    <param-value>1000</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

注意：log4j.properties文件位置放在src下
