问题描述

我已经将log4jConfigLocation放在web.xml中,但我仍然收到以下警告:

I already put the log4jConfigLocation in web.xml, but I still get the following warning:

log4j:WARN No appenders could be found for logger ⤦
    ⤥ (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.

我错过了什么?

推荐答案

如果这是整个log4j.properties文件,它看起来像你永远不会真正创建一个记录器。你需要一行:

If that's the entire log4j.properties file it looks like you're never actually creating a logger. You need a line like:

log4j.rootLogger=debug,A1
