之前环境安装已经介绍过了，下面直接跑个Demo。

1、添加Maven依赖

<dependency>
　　<groupId>org.springframework.amqp</groupId>
　　<artifactId>spring-rabbit</artifactId>
　　<version>1.4.6.RELEASE</version>
</dependency>

<dependency>
　　<groupId>com.rabbitmq</groupId>
　　<artifactId>amqp-client</artifactId>
　　<version>2.2.0</version>
</dependency>

2、发送类：

 package com.jimmy.demo.test;

import java.io.IOException;
import com.rabbitmq.client.Channel;  
import com.rabbitmq.client.Connection;  
import com.rabbitmq.client.ConnectionFactory; 
public class Send {  
    private final static String QUEUE_NAME = "hello";  
  
    public static void main(String[] args) throws IOException {  
        ConnectionFactory factory = new ConnectionFactory();  
        factory.setHost("localhost");  
        Connection connection = factory.newConnection();  
        Channel channel = connection.createChannel();  
  
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);  
        String message = "Hello World!";  
        channel.basicPublish("", QUEUE_NAME, null, message.getBytes());  
        System.out.println(" [x] Sent ‘" + message + "‘");  
  
        channel.close();  
        connection.close();  
    }  
}

接收类：

package com.jimmy.demo.test;
import com.rabbitmq.client.Channel;  
import com.rabbitmq.client.Connection;  
import com.rabbitmq.client.ConnectionFactory;  
import com.rabbitmq.client.QueueingConsumer;  
  
public class Reqv {  
    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();  
  
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);  
        System.out.println(" [*] Waiting for messages. To exit press CTRL+C");  
  
        QueueingConsumer consumer = new QueueingConsumer(channel);  
        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 + "‘");  
        }  
    }  
}

测试先运行Reqv,再运行Send两次，看到如下消费者能够接受到2条消息了
