一旦读取数据，如何停止/杀死消费者？

Question

我使用发布者/订阅者模型以循环方式传递消息。在这里，我使用2个消费者来处理请求。我想在处理一个请求后停止一个消费者。我如何阻止一个消费者？如果是这样，剩下的请求将转给其他消费者。如果消费者无法发回，那么（持久性）数据会发生什么？它会丢失还是会传递给其他消费者？

public class Testing {

    public static void main(String[] args) throws URISyntaxException, Exception {
        BrokerService broker = BrokerFactory.createBroker(new URI(
                "broker:(tcp://localhost:61616)"));
        broker.start();
        Connection connection = null;
        try {
            // Producer
            ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
                    "tcp://localhost:61616");
            connection = connectionFactory.createConnection();
            Session session = connection.createSession(false,
                    Session.AUTO_ACKNOWLEDGE);
            Queue queue = session.createQueue("customerQueue");

            // Consumer
            for (int i = 0; i < 2; i++) {
                MessageConsumer consumer = session.createConsumer(queue);
                if(i == 0)
                {
                consumer.setMessageListener(new ConsumerMessageListener("Consumer " + i));
                }


                consumer.setMessageListener(new TestingOnc("Consumer" + i));


                }

            broker.stop();
        }
    }

}

制片人打电话给我

public synchronized static void createMQRequestForPoster(Long zoneId, List<String> postJobs, int priority) throws JMSException {

        Connection connection = null;
        try {
            connection = factory.createConnection();
            connection.start();
            Session session = connection.createSession(false,
                    Session.CLIENT_ACKNOWLEDGE);
            Destination dest = session
                    .createQueue(SMCConstants.ACTIVEMQ_POST_REQUEST);
            MessageProducer producer = session.createProducer(dest);
            producer.setDeliveryMode(DeliveryMode.PERSISTENT);

            logger.info("List of jobs adding into poster queue: "+postJobs.size());
            for(String str : postJobs) {

                TextMessage message = session.createTextMessage();
                JSONObject obj = new JSONObject();
                obj.put("priority", priority);
                obj.put("zoneId", zoneId);
                obj.put("postJobs", str);
                logger.debug(obj.toString());
                message.setText(obj.toString());
                message.setIntProperty(ActiveMQReqProcessor.REQ_TYPE, 0);
                producer.send(message);
            }
        } catch (JMSException | JSONException e) {
            logger.warn("Failed to add poster request to ActiveMq", e);
        } finally {
            if(connection != null)
                connection.close();
        }
    }
}

能够发送和接收消息。
