Couldn't generate instance Id! org.quartz.SchedulerException: Couldn't get host name!

这个错误通常在使用 Quartz 调度器时发生，因为 Quartz 默认使用本地主机名作为实例 ID。如果您的系统无法获取本地主机名，则会出现此错误。解决此问题的方法之一是手动设置实例 ID，而不是使用默认的主机名。您可以在 Quartz 属性文件中设置实例 ID，例如：

org.quartz.scheduler.instanceId = myInstanceId

这将为 Quartz 创建一个名为“myInstanceId”的实例。请确保此 ID 在您的应用程序中是唯一的。如果您仍然遇到问题，请检查您的网络设置和主机名解析是否正确，并且您是否具有足够的权限来访问系统。
