No appenders could be found for logger (org.springframework.web.context.ContextLoader)

spring中加入log4j不显示日志，报如下信息：

No appenders could be found for logger (org.springframework.web.context.ContextLoader).

解决方法：

1. 在web.xml配置文件中加入

   
   <context-param>
       <param-name>log4jConfigLocationparam-name>
       <param-value>classpath:/config/log4j.propertiesparam-value>
   context-param>
   <listener>
       <listener-class>
           org.springframework.web.util.Log4jConfigListener
       listener-class>
   listener>

2. 再一种解决就是log4j.properties文件要放在src/下
