Question

我正在构建一个REST服务，我有以下类的结构：

public class MyTask implements Runnable {

   @Override
    public void run() {
       //do stuff
    }
}

public class RestController  {

   private MyThreadPool myThreadPool;

   @RequestMapping(value = "/{id}", method = RequestMethod.POST)
   public ResponseEntity<?> getSomething (....){
    myThreadPool.getExecutorService().submit(new MyTask(request));
   }


}


public class MyThreadPool{

    private final static Integer SIZE_OF_POOL = 5;
    private final static Integer KEEP_ALIVE= 5000;
    private final static Integer QUEUE_SIZE = 50;
    private final static Integer MAX_POOL_SIZE = 10;


    private BlockingQueue<Runnable> queue = new PriorityBlockingQueue<Runnable>(QUEUE_SIZE); //pass comparator here? 
    private ExecutorService executorService = new ThreadPoolExecutor(SIZE_OF_POOL, MAX_POOL_SIZE, KEEP_ALIVE, TimeUnit.SECONDS, queue, new ThreadPoolExecutor.CallerRunsPolicy());

    public ExecutorService getExecutorService() {
        return executorService;
    }
}

我的项目中可能有我的request对象有一个整数来表示优先级的场景。

我希望使用此优先级值提交可执行的任务以执行，我不确定在何处实现此逻辑以及如何执行此操作。我知道我必须在某处使用PriorityBlockingQueue并实现Comparator。我也是......

1）在MyThreadPool类中实现 2）或在MyTask中实现逻辑

请问您能说明如何实施此比较器，以便首先执行具有最高优先级的请求吗？

具有PriorityBlockingQueue和实现比较器的ExecutorService
