推荐答案

通常通过让所有非守护进程线程正常完成其工作来实现Java中的正常"关闭.如果您的应用程序在某个端口上侦听关闭"命令，则可以让脚本将该命令触发到该端口，然后您可以使用该脚本为线程设置适当的标志以使其停止工作，从而使JVM关闭.这可能是我看过的最简单的方法.

A "graceful" shutdown in Java is generally achieved by letting all non-daemon threads complete their work normally. If you have your app listen for a "shutdown" command on some port, then you could have the script trigger the command to that port, which you could then use to set appropriate flags for your threads to stop working, letting the JVM shut down. That's probably the simplest way I've seen it done.
