获取有关Java进程终止的通知 [英] Get notification on a Java process termination

问题描述

有一个控制台Java应用程序应该运行，直到它被Ctrl + C停止或关闭控制台窗口。如何将该应用程序编程为在退出之前执行清理代码？

There is a console Java application which is supposed to run untill it is stopped by Ctrl+C or closing the console window. How that application can be programmed to execute a clean up code before exit?

推荐答案

你可以使用关机挂钩。

基本上你需要创建一个执行关机的线程操作，然后将其添加为关闭挂钩。例如：

Basically you need to create a Thread which will perform your shutdown actions, and then add it as a shutdown hook. For example:

class ShutdownHook extends Thread
{
    public void run()
    {
        // perform shutdown actions
    }
}

// Then, somewhere in your code

Runtime.getRuntime().addShutdownHook(new ShutdownHook())
