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

Hierarchy.getDefaultHierarchy介绍

[英]Retrieve the default hierarchy.

In most cases the default LogHierarchy is the only one used in an application. However when security is a concern or multiple independent applications will be running in same JVM it is advantageous to create new Hierarchies rather than reuse default.
[中]检索默认层次结构。
在大多数情况下，默认的LogHierarchy是应用程序中唯一使用的LogHierarchy。然而，当考虑到安全性或多个独立的应用程序将在同一JVM中运行时，创建新的层次结构而不是重用默认值是有利的。
