使用ThreadPoolExecutor，如何获取在线程池中运行的线程的名称？

创建一个重写beforeExecute方法的ThreadPoolExecutor。

private final ThreadPoolExecutor executor = new ThreadPoolExecutor (new ThreadPoolExecutor(10, 10,  0L, TimeUnit.MILLISECONDS,  new linkedBlockingQueue<Runnable>()){       protected void beforeExecute(Thread t, Runnable r) {          t.setName(deriveRunnableName(r));    }    protected void afterExecute(Runnable r, Throwable t) {          Thread.currentThread().setName("");    }    protected <V> RunnableFuture<V> newTaskFor(final Runnable runnable, V v) {         return new FutureTask<V>(runnable, v) {  public String toString() {     return runnable.toString();  }         };     };}

不确定会如何

derveRunnableName()

toString()

编辑：Thread.currentThread（）实际上是在调用afterExecute的beforeExecute中设置的线程。您可以引用Thread.currentThread（），然后在afterExecute中设置名称。这在javadocs中有所说明

protected void afterExecute(Runnable r, Throwable t) { }

编辑
TPE会将Runnable封装在FutureTask中，因此要支持该

toString

newTaskFor
