本文整理了Java中com.yahoo.net.HostName类的一些代码示例，展示了HostName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。HostName类的具体详情如下：
包路径：com.yahoo.net.HostName
类名称：HostName

HostName介绍

[英]Utilities for getting the hostname of the system running the JVM. Detection of the hostname is now done before starting any Vespa programs and provided in the environment variable VESPA_HOSTNAME; if that variable isn't set a default of "localhost" is always returned.
[中]获取运行JVM的系统主机名的实用程序。主机名的检测现在在启动任何Vespa程序之前完成，并在环境变量Vespa_hostname中提供；如果未设置该变量，则始终返回默认值“localhost”。
