  //增加监听器
  public final void addListener(final ThreadCompleteListener listener) {
    listeners.add(listener);
  }
  //移除监听器
  public final void removeListener(final ThreadCompleteListener listener) {
    listeners.remove(listener);
  }
  private final void notifyListeners() {
    for (ThreadCompleteListener listener : listeners) {
      listener.notifyOfThreadComplete(this);

  }
  @Override
  public final void run() {
    try {
      doRun();
    } finally {
      notifyListeners();
