1、在linux机器上安装rabbitmq,并启动服务：
这里写图片描述
2、下载MQ 客户端jar包：amqp-client-3.5.4.jar
3、通过rabbitmq输出”Hello World!”

这里写图片描述

其中P代表生产者、C表示消费者、中间红色部分代表消息队列

4、生产者客户端的发送消息程序如下：

package com.mq;import java.io.IOException;  import java.util.concurrent.TimeoutException;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 {          try {        ConnectionFactory factory = new ConnectionFactory();          factory.setHost("192.168.11.32");          Connection connection;            connection = factory.newConnection();        Channel channel = connection.createChannel();          channel.queueDeclare(QUEUE_NAME, false, false, false, null);          String message = "Hello World!";          for(int i=0;i<10;i++){        channel.basicPublish("", QUEUE_NAME, null, message.getBytes());          System.out.println(" [x] Sent '" + message + "'");          }        channel.close();          connection.close();         } catch (TimeoutException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }      }  }

运行给过如下：

 [x] Sent 'Hello World!' [x] Sent 'Hello World!' [x] Sent 'Hello World!' [x] Sent 'Hello World!' [x] Sent 'Hello World!' [x] Sent 'Hello World!'

这里写图片描述
5、消费者客户端接收消息程序如下：

package com.mq;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("192.168.11.32");        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 + "'");        }    }  }

运行结果如下：

 [*] Waiting for messages. To exit press CTRL+C [x] Received 'Hello World!' [x] Received 'Hello World!' [x] Received 'Hello World!' [x] Received 'Hello World!' [x] Received 'Hello World!' [x] Received 'Hello World!' [x] Received 'Hello World!' [x] Received 'Hello World!'

如果消费者出现“[x] Received ‘Hello World!’”说明已接收到此消息信息。
