本文整理了Java中org.apache.log4j.Logger.getRootLogger()方法的一些代码示例，展示了Logger.getRootLogger()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。Logger.getRootLogger()方法的具体详情如下：
包路径：org.apache.log4j.Logger
类名称：Logger
方法名：getRootLogger

Logger.getRootLogger介绍

[英]Return the root logger for the current logger repository.

The #getName method for the root logger always returns stirng value: "root". However, calling Logger.getLogger("root") does not retrieve the root logger but a logger just under root named "root".

In other words, calling this method is the only way to retrieve the root logger.
[中]返回当前记录器存储库的根记录器。
根记录器的#getName方法始终返回stirng值：“root”。但是，调用Logger.getLogger("root")不会检索根记录器，而是检索名为“root”的根下的记录器。
换句话说，调用此方法是检索根记录器的唯一方法。
