Log4j2:没有log4j-web模块可用

I am trying to set the status level of my config to "info", but I am getting the following output:

我试图将配置的状态级别设置为“info”，但我得到了以下输出:

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.

My log4j2.xml has the following

我的log4j2。xml具有以下

I have download the jar file (log4j-web-2.6.2.jar) and added it to my class path, but I still get the same output for some reason. What could I be doing wrong? I am able to output DEBUG status levels, but not INFO which is odd.

我已经下载了jar文件(log4j-web-2.6.2.jar)并将它添加到我的类路径中，但是出于某些原因，我仍然得到相同的输出。我做错了什么?我能够输出调试状态级别，但不能够输出奇怪的信息。

2 个解决方案

#1

At first, I thought the problem was because I have servlet-api jar in my classpath, which I need, but removing that did not fix the problem, for me. In the end, all I had to do was just add the log4 web jar file from mvnrepository to your classpath and you're set!

一开始，我认为问题在于我的类路径中有servlet-api jar，这是我需要的，但是对我来说，删除它并不能解决问题。最后，我所要做的就是将来自mvnrepository的log4 web jar文件添加到您的类路径中，您就完成了!

The status="info" at the beginning of the configuration file is for internal log4j2 debug messages. If you set it to trace you will see details on how log4j2 is configured.

配置文件开头的状态=“info”用于内部log4j2调试消息。如果将其设置为trace，您将看到关于如何配置log4j2的详细信息。

That has nothing to do with your application logging though. You say you are able to output debug messages, I assume that mean that the logging itself works as expected (If there's a problem there then please show your full configuration. )

但这与应用程序日志无关。您说您可以输出调试消息，我假设这意味着日志记录本身可以正常工作(如果存在问题，请显示您的完整配置)。
