Я могу написать Java-программу, используя Rabbit Java API, выполняя следующие действия:

Клиент отправляет сообщение по обмену / очереди Rabbit MQ с идентификатором корреляции (например, UUID - «348a07f5-8342-45ed-b40b-d44bfd9c4dde»).

Сервер получает сообщение.

Сервер отправляет ответное сообщение по обмену / очереди Rabbit MQ с тем же идентификатором корреляции - «348a07f5-8342-45ed-b40b-d44bfd9c4dde».

Клиент получил коррелированное сообщение только в той же ветке, что и 1.

Ниже приведены Send.java и Recv.java с использованием API-интерфейсов Rabbit. Мне нужна помощь, чтобы преобразовать этот пример, чтобы использовать интеграцию Spring AMQP, особенно получение части на шаге 4. Я ищу что-то вроде метода приема, который может фильтровать сообщения, используя Id корреляции.

Send.java:

import java.util.UUID;

import com.rabbitmq.client.AMQP.BasicProperties;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.QueueingConsumer;

public class Send {

    private final static String REQUEST_QUEUE = "REQUEST.QUEUE";
    private final static String RESPONSE_QUEUE = "RESPONSE.QUEUE";

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

        channel.queueDeclare(REQUEST_QUEUE, false, false, false, null);
        String message = "Hello World!";
        String cslTransactionId = UUID.randomUUID().toString();
        BasicProperties properties = (new BasicProperties.Builder())
            .correlationId(cslTransactionId)
            .replyTo(RESPONSE_QUEUE).build();

        channel.basicPublish("", REQUEST_QUEUE, properties, message.getBytes());

        System.out.println("Client Sent '" + message + "'");


        Channel responseChannel = connection.createChannel();
        responseChannel.queueDeclare(RESPONSE_QUEUE, false, false, false, null);

        QueueingConsumer consumer = new QueueingConsumer(channel);
        responseChannel.basicConsume(RESPONSE_QUEUE, false, consumer);
        String correlationId = null;
        while (true) {
            QueueingConsumer.Delivery delivery = consumer.nextDelivery();
            String responseMessage = new String(delivery.getBody());
            correlationId = delivery.getProperties().getCorrelationId();
            System.out.println("Correlation Id:" + correlationId);
            if (correlationId.equals(cslTransactionId)) {
                    System.out.println("Client Received '" + responseMessage + "'");
                responseChannel.basicAck(delivery.getEnvelope().getDeliveryTag(), true);
                break;
            }
        }

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

Recv.java

import com.rabbitmq.client.ConnectionFactory;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.QueueingConsumer;
import com.rabbitmq.client.AMQP.BasicProperties;

public class Recv {

    private final static String REQUEST_QUEUE = "REQUEST.QUEUE";
    private final static String RESPONSE_QUEUE = "RESPONSE.QUEUE";

    public static void main(String[] argv) throws Exception {

        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel();

        channel.queueDeclare(REQUEST_QUEUE, false, false, false, null);
        System.out.println(" [*] Waiting for messages. To exit press CTRL+C");

        QueueingConsumer consumer = new QueueingConsumer(channel);
        channel.basicConsume(REQUEST_QUEUE, true, consumer);
        String correlationId = null;
        while (true) {
            QueueingConsumer.Delivery delivery = consumer.nextDelivery();
            String message = new String(delivery.getBody());
            correlationId = delivery.getProperties().getCorrelationId();
            System.out.println("Correlation Id:" + correlationId);
            System.out.println("Server Received '" + message + "'");
            if (correlationId != null)
                break;
            }

            String responseMsg = "Response Message";
            Channel responseChannel = connection.createChannel();
            responseChannel.queueDeclare(RESPONSE_QUEUE, false, false, false, null);
            BasicProperties properties = (new BasicProperties.Builder())
            .correlationId(correlationId).build();

            channel.basicPublish("", RESPONSE_QUEUE, properties,responseMsg.getBytes());

            System.out.println("Server Sent '" + responseMsg + "'");

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

После запуска конфигурации Java, предоставленной gary, я пытаюсь переместить конфигурацию в формат XML для добавления на сервер прослушивателя. Ниже приведена конфигурация XML:
