A basic consumer example to consume a message from RabbitMQ Queue.

Consumer

public class Consumer {
    private final static String QUEUE_NAME = "Greet";

    public static void main(String[] argv)
            throws java.io.IOException,
            java.lang.InterruptedException {

        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        factory.setUsername("guest");
        factory.setPassword("guest");
        Connection connection = factory.newConnection();

        //Create a channel
        Channel channel = connection.createChannel();

        //Queue declare, if queue is already declared it returns a DeclareOk
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);
        System.out.println(" [*] Waiting for messages. To exit press CTRL+C");

        QueueingConsumer consumer = new QueueingConsumer(channel);

        //basic.consume amqp command to consume the message from the queue
        channel.basicConsume(QUEUE_NAME, true, consumer);

        while (true) {
            QueueingConsumer.Delivery delivery = consumer.nextDelivery();
            String message = new String(delivery.getBody());
            System.out.println(" [x] Received '" + message + "'");
        }
    }
}
