mybatis WARN No appenders could be found for logger的解决方法

log4j:WARN No appenders could be found for logger (org.apache.ibatis.logging.LogFactory).
log4j:WARN Please initialize the log4j system properly.

log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

网上有好多解决办法都不管用，这个提示应该是读入web应用程序的log4j.properties文件之前就报出来了。是在加载org.springframework.web.context.ContextLoader这个listener的时候没找到log4j的配置文件造成的。

仔细查看web.xml发现在加载org.springframework.web.context.ContextLoader这个listener之后才加载org.springframework.web.util.Log4jConfigListener，把log4j的配置放到org.springframework.web.context.ContextLoader之前，就可以解决这个问题了

web.xml中

<!-- 以下3项参数与log4j的配置相关 -->  

    <context-param>

        <param-name>log4jConfigLocation</param-name>

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

    </context-param>  

    <context-param>

        <param-name>log4jRefreshInterval</param-name>

        <param-value>60000</param-value>

    </context-param>

    <listener>

        <listener-class>

            org.springframework.web.util.Log4jConfigListener

        </listener-class>

    </listener>

<!-- end -->  

    <listener>

        <listener-class>

            org.springframework.web.context.ContextLoaderListener

        </listener-class>

    </listener>
