如何检查log4j2是否已配置 [英] How to check if log4j2 has been configured or not

问题描述

当您不提供log4j2配置时，我们都熟悉此消息：

We're all familiar with this message when you don't provide a configuration for log4j2:

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.

如何检查log4j2是否尚未配置，以便我可以使用默认配置进行初始化？

How can I check if log4j2 is not yet configured so that I can initialize with a default configuration if needed?

推荐答案

我最后创建了自己的ConfigurationFactory并注册

I ended up creating my own ConfigurationFactory and register it with

-Dlog4j.configurationFactory

这样你的ConfigurationFactory会知道是否已被调用。

That way your ConfigurationFactory will know whether it's been invoked yet or not.
