Configuration 在springframework下：WARN:WARN找不到记录器（org.springframework.web.context.ContextLoader）的追加器

我花了一整天的时间试图解决我在一个webapp中使用log4j时遇到的日志记录问题。无论我做什么，我都无法摆脱以下几点：

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

为了清楚起见，我已经阅读了这里所有关于堆栈溢出的文章来解决这个问题。我读过log4j手册。我已经学习了十几种不同的教程。我尝试了属性方法和XML方法（分别是log4j.properties和log4j.XML）。另外，我已经确认正在读取log4j.xml文件。除了服务器在启动时告诉我这一点之外，我还可以通过.xml文件影响反馈级别。因此，是的，log4j.xml文件位于类路径中

我知道我错过了一些简单和基本的东西。以下是相关文件：

LOG4J.XML（/WEB-INF）：

和WEB.XML（/WEB-INF）：

上下文配置位置
/WEB-INF/spring/root-context.xml
/WEB-INF/spring/app-context.xml
org.springframework.web.util.Log4jConfigListener
log4jConfigLocation
/WEB-INF/log4j.xml
org.springframework.web.context.ContextLoaderListener
appServlet
org.springframework.web.servlet.DispatcherServlet
上下文配置位置
/WEB-INF/spring/appServlet/servlet-context.xml
1.
appServlet
/

和APP-CONTEXT.XML（/WEB-INF/spring）：

和APP-CONTEXT-MONGO.XML（/WEB-INF/spring）：

/WEB-INF/spring/database.properties

最后是ROOT-CONTEXT.XML（/WEB-INF/spring）：

我错过了什么

谢谢。

你试过这个吗

 <logger name="org.springframework.web">
     <level value="info" /> 
     <appender-ref ref="console" />     
 </logger>

将这些行放在

web.xml

的开头：

org.springframework.web.util.Log4jConfigListener
log4jConfigLocation
classpath:/main/resources/log4j.xml

这是否回答了您的问题？
