RabbitMQ无法接收消息

Question

在示例中，我使用的是与本教程相同的类： https://www.rabbitmq.com/tutorials/tutorial-one-java.html

我有两节课： Send.java

import com.rabbitmq.client.Connection;
import com.rabbitmq.client.Channel;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

public class Send {

    public static final String QUEUE_NAME="hello";



    public static void main(String[] args) {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        Connection connection=null;
        Channel channel =null;
        try {
            connection = factory.newConnection();
            channel = connection.createChannel();
            channel.queueDeclare(QUEUE_NAME,false,false,false,null);
            String message = "Hello word toto";
            channel.basicPublish("",QUEUE_NAME,null,message.getBytes());
            System.out.println(" [ x ] Sent '"+message+"'");
        } catch (IOException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        }finally {
            try {
                channel.close();
            } catch (IOException e) {
                e.printStackTrace();
            } catch (TimeoutException e) {
                e.printStackTrace();
            }
            try {
                connection.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

和接收类：

import com.rabbitmq.client.*;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

public class Receiv{
    private final static String QUEUE_NAME = "hello";

    public static void main(String[] args) {
        Connection connection=null;
        Channel channel=null;
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        try {
            connection = factory.newConnection();
            channel = connection.createChannel();
            channel.queueDeclare(QUEUE_NAME, false, false, false, null);
            System.out.println(" [*] Waiting for messages. To exit press CTRL+C");
            Consumer consumer = new DefaultConsumer(channel){
                @Override
                public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body)
                        throws IOException {
                    String message = new String(body, "UTF-8");
                    System.out.println(" [x] Received '" + message + "'");
                }
            };
            channel.basicConsume(QUEUE_NAME, true, consumer);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        }finally {
            try {
                channel.close();
            } catch (IOException e) {
                e.printStackTrace();
            } catch (TimeoutException e) {
                e.printStackTrace();
            }
            try {
                connection.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
} 

我得到的是我编译的例子，但我没有看到收到的消息

谢谢。
