java - 如何中断执行线程

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，其方法为:

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

主类:

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

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

您可以发布所有相关代码吗？根据您提供的信息，我无法重现您所描述的行为。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
....
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");
        }
    }
}
