我花了一整天的时间试图解决我在 web 应用程序中使用 log4j 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,我已经阅读了有关 Stack Overflow 上解决此问题的所有文章。我已经阅读了 log4j 手册。我已经学习了十几个不同的教程。我已经尝试过属性方法和 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。除了服务器在启动期间告诉我这一事实之外,我还可以通过 .xml 文件影响反馈级别。所以,是的,log4j.xml 文件在 CLASSPATH 中。

我知道我错过了一些简单而基本的东西。以下是相关文件:

我错过了什么?

谢谢你。

最佳答案

你试过这个吗?

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

关于configuration - Spring框架下: WARN: WARN No appenders could be found for logger (org. springframework.web.context.ContextLoader),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/14433023/
