1、使用一个volatile的共享变量

2、使用interrupt方法

import java.util.concurrent.TimeUnit;/** * ThreadTest */public class ThreadTest implements Runnable {    private volatile boolean stop = false;    @Override    public void run() {        while (!stop) {            System.out.println(Thread.currentThread().getName() + " is running...");            try {                TimeUnit.MILLISECONDS.sleep(1000);            } catch (InterruptedException e) {                System.out.println("wake up from block");                stop = true;            }        }        System.out.println(Thread.currentThread().getName() + " is exiting...");    }    public static void main(String[] args) {        ThreadTest threadTest = new ThreadTest();        Thread t1 = new Thread(threadTest);        t1.start();        try {            TimeUnit.MILLISECONDS.sleep(3000);        } catch (InterruptedException e) {            //        }        // 1、使用 volatile共享变量        threadTest.stop = true;        // 2、使用interrupt方法        System.out.println("Interrupt thread:" + t1.getName());        t1.interrupt();        try {            TimeUnit.MILLISECONDS.sleep(3000);        } catch (InterruptedException e) {            //        }        System.out.println("Stopping application...");    }}

2种可能的运行结果：

Thread-0 is running...Thread-0 is running...Thread-0 is running...Interrupt thread:Thread-0Thread-0 is running...wake up from blockThread-0 is exiting...Stopping application...
