java如何中断执行器线程

Question

中断执行器线程的正确方法是什么？ 我有这个： 名为Worker的线程类，方法为：

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

和主类，包括：

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

我试图调用worker.interrupt();或executorService.shutdownNow();，但我的线程继续运行，isInterrupted（）为false

你能发布所有相关代码吗？根据你提供的信息，我无法重现你描述的行为。请参见下面一个按预期工作的SSCCE输出：

work pool-1-thread-1:false
work pool-1-thread-1:false
work pool-1-thread-1:false
....
Thread has been interrupted

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");
        }
    }
}
