1.  Callable 接口

 获取线程运行状态（get、get（long timeout）），取消线程（cancel（boolean  mayinterruptifrunning））。isCancel，isDone等。

1.  实现callable 接口，

2.  创建线程池。submit thread

例如以下所看到的：

 Future< ? > processFuture = submitTask(
            new ProcessPbxPhoneThread(queue, phoneHandler, runningLock, runningFlagMap));

 private class ProcessPbxPhoneThread implements Callable<Boolean>
   {
      private BlockingQueue<PbxPhone> queue;
      private IPbxNotificationHandler<PbxPhone> phoneHandler;
      private ReadWriteLock runningLock;
      private Map<String, Boolean> runningFlagMap;
      private int processedPhoneCount = 0;
      private long currentTime;

      public ProcessPbxPhoneThread(BlockingQueue<PbxPhone> queue,
            IPbxNotificationHandler<PbxPhone> phoneHandler, ReadWriteLock runningLock,
            Map<String, Boolean> runningFlagMap)
      {
         this.queue = queue;
         this.phoneHandler = phoneHandler;
         this.runningFlagMap = runningFlagMap;
         this.runningLock = runningLock;
      }

      @Override
      public Boolean call()
         throws Exception
      {
         while (true)
         {
            PbxPhone phone = queue.take();
            if (processedPhoneCount % 100 == 0)
            {
               long now = System.currentTimeMillis();
               if (currentTime != 0)
               {
                  double speed = processedPhoneCount * 1000.0 * 60 / (now - currentTime);
                  log.debug("ProcessPbxPhoneThread phone process speed:{}*m", speed);
               }
               currentTime = now;
               processedPhoneCount = 0;
            }
            processedPhoneCount++;

            if (null != phone.getLines())
            {
               currentTime("invokePhoneHander");
               PbxNotification<PbxPhone> notification = new PbxNotification<PbxPhone>(
                     phoneHandler.getNotificationType(), NotificationOperation.INSERT,
                     phone.getUuid().toString(), phone);
               if (!phoneHandler.objectChanged(notification))
               {
                  logSpentTime("invokePhoneHander");
                  try
                  {
                     runningLock.writeLock().lock();
                     runningFlagMap.put("runningFlag", false);
                     break;
                  }
                  finally
                  {
                     runningLock.writeLock().unlock();
                  }
               }
               else
               {
                  logSpentTime("invokePhoneHander");
               }
            }
            else
            {
               break;
            }
         }
         return true;
      }
   }

submitTask 利用封装好的线程池提交线程：

 protected Future< ? > submitTask(Callable< ? > task)
   {
      return this.cucmDriverFactory.<strong style="background-color: rgb(255, 0, 0);">getExecutorService</strong>().submit(task);
   }

线程池创建例如以下代码：

  @Override
   public void initialize()
   {
      executorService = Executors.newCachedThreadPool(new DefaultThreadFactory("CucmDriverFactor-"));
   } 

@Override
   public ExecutorService getExecutorService()
   {
      if (executorService.isShutdown() || executorService.isTerminated())
      {
         initialize();
      }
      return this.executorService;
   }

 /**
    * The thread factory, with name Prefix. Copied from ThreadPoolExecutor.DefaultThreadFactory
    */
   public static class DefaultThreadFactory implements ThreadFactory {
       private final ThreadGroup group;
       private final AtomicInteger threadNumber = new AtomicInteger(1);
       private final String namePrefix;

       public DefaultThreadFactory(String namePrefix) {
           SecurityManager s =
