我试图将配置的状态级别设置为“info”,但我得到以下输出：

INFO Log4j appears to be running in a Servlet environment, but there's no log4j-web module available. If you want better web container support, please add the log4j-web JAR to your web archive or server lib directory.

我的log4j2.xml有以下内容

    <?xml version="1.0" encoding="UTF-8"?>

我已经下载了jar文件(log4j-web-2.6.2.jar)并将其添加到我的类路径中,但由于某种原因我仍然得到相同的输出.我能做错什么？我能够输出DEBUG状态级别,但不能输出奇怪的INFO.

解决方法:

起初,我认为问题是因为我在我的类路径中有servlet-api jar,这是我需要的,但删除它并没有解决问题,对我而言.最后,我所要做的只是将mvnrepository中的log4 web jar文件添加到你的类路径中,然后就可以了！
