如何从线程池中获取线程ID？ [英] How to get thread id from a thread pool?

问题描述

我有一个固定的线程池，我将任务提交给（仅限于 5 个线程）。如何找出那些 5 线程中的哪一个执行我的任务（类似 5 的第3个线程正在执行此任务）？

I have a fixed thread pool that I submit tasks to (limited to 5 threads). How can I find out which one of those 5 threads executes my task (something like "thread #3 of 5 is doing this task")?

ExecutorService taskExecutor = Executors.newFixedThreadPool(5);

//in infinite loop:
taskExecutor.execute(new MyTask());
....

private class MyTask implements Runnable {
    public void run() {
        logger.debug("Thread # XXX is doing this task");//how to get thread id?
    }
}

推荐答案

使用 Thread.currentThread（）：

private class MyTask implements Runnable {
    public void run() {
        long threadId = Thread.currentThread().getId();
        logger.debug("Thread # " + threadId + " is doing this task");
    }
}
