    </dependency>

二、使用步骤

1. 消息生产者

package com.julong.hello;

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

/**
 * 消息发送简单示例
 * @author julong
 * @date 2022年1月19日 上午10:40:17
 * @desc 
 */
public class SendMessage {
  private final static String QUEUE_NAME = "hello-rabbitmq";
  public static void main(String[] args) {
    // TODO Auto-generated method stub
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("192.168.10.222");//设置连接地址
    factory.setPort(5672);//连接端口号
    factory.setUsername("julong");//账户
    factory.setPassword("julong");//密码
    try {
      Connection connection = factory.newConnection();
      Channel channel = connection.createChannel();
      //queue the name of the queue 队列名称
      //durable true if we are declaring a durable queue (the queue will survive a server restart) 是否持久化
      //exclusive true if we are declaring an exclusive queue (restricted to this connection) 排他性
      //autoDelete true if we are declaring an autodelete queue (server will delete it when no longer in use) 是否自动删除
      //arguments other properties (construction arguments) for the queue 其他参数
      channel.queueDeclare(QUEUE_NAME, false, false, false, null);
      String message = "Hello World !"+ QUEUE_NAME;
      //发布消息
      //exchange the exchange to publish the message to 交换机
      //routingKey the routing key 路由键
      //props other properties for the message - routing headers etc 其他配置属性
      //body the message body 消息内容
      for(int i = 0;i<5;i++){
        channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
        System.out.println(" [消息发送] Sent '" + message + "'");
      }
    
    } catch (Exception e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
  }

}

2.消息消费者

package com.julong.hello;

import java.io.IOException;

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.Consumer;
import com.rabbitmq.client.DefaultConsumer;
import com.rabbitmq.client.Envelope;

/**
 * 消息接收简单示例
 * @author julong
 * @date 2022年1月19日 上午10:40:17
 * @desc 
 */
public class ReceiveMessage {
  private final static String QUEUE_NAME = "hello-rabbitmq";
  public static void main(String[] args) {
    // TODO Auto-generated method stub
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("192.168.10.222");//设置连接地址
    factory.setPort(5672);//连接端口号
    factory.setUsername("julong");//账户
    factory.setPassword("julong");//密码
    try {
      //创建连接
        Connection connection = factory.newConnection();
        //创建 channel
        Channel channel = connection.createChannel();
        //创建队列
        //queue the name of the queue 队列名称
      //durable true if we are declaring a durable queue (the queue will survive a server restart) 是否持久化
      //exclusive true if we are declaring an exclusive queue (restricted to this connection) 排他性
      //autoDelete true if we are declaring an autodelete queue (server will delete it when no longer in use) 是否自动删除
      //arguments other properties (construction arguments) for the queue 其他参数
        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, BasicProperties properties,
            byte[] body) throws IOException {
          // TODO Auto-generated method stub
          String message = new String(body, "UTF-8");
            System.out.println(" [接收消息] Received '" + message + "'");
        }
          
        };
        //设置消息回调
        channel.basicConsume(QUEUE_NAME,true, consumer);
    } catch (Exception e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
  }

}

结果
