没有为每个接收者确认调用ConfirmListener

Question

我有一个简单的工作队列案例，当发件人想要确认消息被激活或接收方没有。

private final static String QUEUE_NAME = "hello";

public static void main(String[] argv) throws Exception
{
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("localhost");
    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    final boolean durable = true;

    channel.queueDeclare(QUEUE_NAME, durable, false, false, null);

    System.out.println(channel.confirmSelect());

    CountDownLatch latch = new CountDownLatch(10);

    channel.addConfirmListener(new ConfirmListener()
    {
        @Override
        public void handleAck(final long deliveryTag, final boolean multiple) throws IOException
        {

            System.out.println("Got ack " + deliveryTag);
            latch.countDown();
        }

        @Override
        public void handleNack(final long deliveryTag, final boolean multiple) throws IOException
        {
            System.out.println("Got no-ack " + deliveryTag);
            latch.countDown();
        }
    });

    channel.basicQos(1);

    IntStream.rangeClosed(1,10).forEach(e -> {

                try
                {
                    String message = "Hello World! " + e;
                    channel.basicPublish("", QUEUE_NAME, null, message.getBytes("UTF-8"));
                    System.out.println(" [x] Sent '" + message + "'");
                }
                catch (IOException err)
                {
                    err.printStackTrace();
                }
            });

    latch.await(30, TimeUnit.SECONDS);

    channel.close();
    connection.close();
}

当在接收方时，我使用auto-ack或per message manual ack 我从ConfirmListener触发了几个handleAck。

 [x] Sent 'Hello World! 1'
 [x] Sent 'Hello World! 2'
 [x] Sent 'Hello World! 3'
 [x] Sent 'Hello World! 4'
 [x] Sent 'Hello World! 5'
 [x] Sent 'Hello World! 6'
 [x] Sent 'Hello World! 7'
 [x] Sent 'Hello World! 8'
 Got ack 1
 [x] Sent 'Hello World! 9'
 [x] Sent 'Hello World! 10'
 Got ack 6
 Got ack 10

这可以实现每条消息的确认吗？

问候。
