Push mode下实现每隔一段时间push

[yxiaamz]

我现在的问题是在push mode下，我用rabbitMQ的handleDelivery这个callback function来监听我的reduced price queue.但是问题是，这个function一直在执行，它一直在监听queue，我要做用ScheduledExecutorService到每隔一段时间来执行一下，没法先让它停止.
我查了也没找到当MQ为空时，停止consumer的方法。既然没法停止，我就想还是让consumer一直监听，但是每隔一段时间push一下从queue里得到的东西,但是ScheduledExecutorService 重写run()方法，这个方法是没有参数的，没办法把从queue里得到的东西传进去。
大家有什么好方法吗？谢谢！

public class MyRunnableTask implements Runnable {
    public MyRunnableTask(Queue q) {
        //do stuff here
    }
     public void run() {
         // do stuff here
     }
}
scheduleAtFixedRate (new MyRunnableTask(1), long initialDelay, long period, TimeUnit timeunit);

老师这个是我的代码，我是想实现callback function一直给list加收到的product，然后30s 发送一次product list，然后把ArrayList清空，但是从我跑的情况来看，只有callback function再一直add product进list，但是重写的run()方法没有像我设置的那样每隔三十秒发送一次list，只是最开始执行了一次。
但是我用ScheduledExecutorService写的crawler就可以实现excture at fix rate，不知道哪里有问题。
这是我的repo: https://github.com/xiayank/Price-Monitor-Push-Server.
主要代码：
Main():

final MySQLAccess sqlAccess = new MySQLAccess(mysql_host, mysql_user, mysql_psw,mysql_db);

		ConnectionFactory factory = new ConnectionFactory();
		factory.setHost("127.0.0.1");
		Connection connection = null;

		try {
			connection = factory.newConnection();
			Channel channel = connection.createChannel();
			channel.queueDeclare("LevelOne",true,false,false,null);

			final ArrayList<Product>reducedList = new ArrayList<>();

			ScheduledExecutorService scheduledThreadPool = Executors.newScheduledThreadPool(5);

			TestRunnable testRunnable = new TestRunnable(reducedList, sqlAccess);

			scheduledThreadPool.scheduleAtFixedRate(testRunnable,1,60, TimeUnit.SECONDS);

			Consumer consumer = new DefaultConsumer(channel){
				@Override
				public void handleDelivery(String consumerTag, Envelope envelope,
										   AMQP.BasicProperties properties, byte[] body)
						throws IOException {

					Product product = (Product) SerializationUtils.deserialize(body);
					System.out.println(product.productId);
					reducedList.add(product);

				}
			};

			channel.basicConsume("LevelOne", true, consumer);
		} catch (IOException e) {
			e.printStackTrace();
		} catch (TimeoutException e) {
			e.printStackTrace();
		}

TestRunnable.class

public class TestRunnable implements Runnable {
    private static final long serialVersionUID = 1L;
    static final String mysql_host = "127.0.0.1:3306";
    static final String mysql_db = "project";
    static final String mysql_user = "root";
    static final String mysql_psw = "1127";
    ArrayList<Product> reducedList = null;
    MySQLAccess sqlAccess = null;

    public TestRunnable(ArrayList<Product> reducedList, MySQLAccess sqlAccess){
       this.reducedList = reducedList;
       this.sqlAccess = sqlAccess;
    }

    @Override
    public void run() {
        System.out.println("60 s run again!!!!");
        for(Product product : reducedList){
          //send product list
             }
        reducedList.clear();
    }

}
