    </dependency>
    
    //2、web.xml配置
    <context-param>
         <param-name>log4jConfiguration</param-name>
         <param-value>classpath:log4j2.xml</param-value>
    </context-param>
    <context-param>
         <param-name>log4jRefreshInterval</param-name>
         <param-value>60000</param-value>
