Question

中断执行程序线程的正确方法是什么？我有这个：名为Worker的线程类，方法：

public void run() {
    while(!(Thread.currentThread().isInterrupted()){
        System.out.println("work " + Thread.currentThread().getName() + ":" + Thread.currentThread().isInterrupted());
    }
}

主要课程：

ExecutorService executorService = Executors.newFixedThreadPool(threadCount);
Worker worker = new Worker();                   
executorService.execute(worker);

我尝试调用worker.interrupt();或executorService.shutdownNow();，但我的线程继续，isInterrupted（）为false。

您可以发布所有相关代码吗？根据您提供的信息，我无法重现您描述的行为。请参阅下面的SSCCE按预期工作 - 输出：

work pool-1-thread-1：false
  work pool-1-thread-1：false
  work pool-1-thread-1：false
  ....
  线程已被中断

代码：

public class Test {

    public static void main(String[] args) throws InterruptedException {
        ExecutorService executorService = Executors.newFixedThreadPool(1);
        Worker worker = new Worker();
        executorService.execute(worker);
        executorService.shutdownNow();
    }

    public static class Worker extends Thread {

        public void run() {
            while (!Thread.currentThread().isInterrupted()) {
                System.out.println("work " + Thread.currentThread().getName() + ":" + Thread.currentThread().isInterrupted());
            }
            System.out.println("Thread has been interrupted");
        }
    }
}
