本文整理了Java中org.apache.logging.log4j.LogManager.getContext()方法的一些代码示例，展示了LogManager.getContext()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。LogManager.getContext()方法的具体详情如下：
包路径：org.apache.logging.log4j.LogManager
类名称：LogManager
方法名：getContext

LogManager.getContext介绍

[英]Returns the current LoggerContext.

WARNING - The LoggerContext returned by this method may not be the LoggerContext used to create a Logger for the calling class.
[中]返回当前LoggerContext。
警告-此方法返回的LoggerContext可能不是用于为调用类创建记录器的LoggerContext。
