线程池中线程的重写中断方法

线程池中线程的重写中断方法

本文介绍了线程池中线程的重写中断方法的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

说我有这个:

class Queue {
  private static ExecutorService executor = Executors.newFixedThreadPool(1);

  public void use(Runnable r){
    Queue.executor.execute(r);
  }

}

我的问题是-如何定义池中使用的线程,特别是想覆盖池中线程的中断方法:

my question is - how can I define the thread that's used in the pool, specifically would like to override the interrupt method on thread(s) in the pool:

   @Override
    public void interrupt() {
      synchronized(x){
        isInterrupted = true;
        super.interrupt();
      }
    }

推荐答案

通过指定 ThreadFactory .

Executors.newFixedThreadPool(1, new ThreadFactory() {
    @Override
    public Thread newThread(Runnable r) {
        return new Thread(r) {
            @Override
            public void interrupt() {
                // do what you need
            }
        };
    }
});

当然,ThreadFactory可以用lambda表示.

Sure, a ThreadFactory can be expressed by a lambda.

ThreadFactory factory = (Runnable r) -> new YourThreadClass(r);

如果线程不需要其他设置(例如使其成为守护程序),则可以使用方法引用.但是,构造函数YourThreadClass(Runnable)应该存在.

If there is no additional setup needed for a thread (like making it a daemon), you can use a method reference. The constructor YourThreadClass(Runnable) should exist, though.

ThreadFactory factory = YourThreadClass::new;

我建议您阅读 ThreadPoolExecutor Executors .他们提供了很多信息.

I'd advise reading the docs of ThreadPoolExecutor and Executors. They are pretty informative.
