本文整理了Java中org.apache.log4j.LogManager类的一些代码示例，展示了LogManager类的具体用法。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类的具体详情如下：
包路径：org.apache.log4j.LogManager
类名称：LogManager

LogManager介绍

[英]Use the LogManager class to retreive Loggerinstances or to operate on the current LoggerRepository. When the LogManager class is loaded into memory the default initalzation procedure is inititated. The default intialization procedure is described in the short log4j manual.
[中]使用LogManager类检索Loggerinstances或操作当前LoggerRepository。当LogManager类被加载到内存中时，默认的初始化过程被初始化。默认初始化过程在short log4j manual中描述。
