pom：

      <modelVersion>4.0.0</modelVersion>

创建连接的工具类：

package com.toov5.utils;
    
    import java.io.IOException;
    import java.util.concurrent.TimeoutException;
    
    import com.rabbitmq.client.Connection;
    import com.rabbitmq.client.ConnectionFactory;
     
    //没有做成单例的  VirtualHost 需要复用
    public class MQConnectionUtils {
        //创建新的连接
        public static Connection newConnection() throws IOException, TimeoutException {
             //创建连接工厂
        ConnectionFactory factory= new ConnectionFactory();
        //链接地址
        factory.setHost("192.168.91.6");
        //用户名称
        factory.setUsername("admin");
        //用户密码
        factory.setPassword("admin");
        //amqp端口号
        factory.setPort(5672);
        //连接virtualhost
        factory.setVirtualHost("/admin_toov5");
        Connection connection = factory.newConnection();
            return connection;
        }
        
        
    }

Producer类

package com.toov5.Producer;
    
    import java.io.IOException;
    import java.util.concurrent.TimeoutException;
    
    import com.rabbitmq.client.Channel;
    import com.rabbitmq.client.Connection;
    import com.toov5.utils.MQConnectionUtils;
    
    public class Producer {
        //队列名称
        private static final String UEUE_NAME = "test_queue";
        
        public static void main(String[] args) throws IOException, TimeoutException {
            //创建新的连接
        Connection connection = MQConnectionUtils.newConnection();
           //创建Channel
            Channel channel = connection.createChannel();
            //创建队列
            channel.queueDeclare(UEUE_NAME, false, false, false, null);
            //创建message
            String msg = "toov5_message";
            System.out.println("生产者投递消息"+msg);
            //生产者发送消息
            channel.basicPublish("",UEUE_NAME, null, msg.getBytes());
            //关闭通道和连接
             channel.close();
             connection.close();
        }
    }

运行结果，看下这个队列

模拟get message

consumer跟 producer基本类似

package com.toov5.Consumer;
    
    import java.io.IOException;
    import java.util.concurrent.TimeoutException;
    
    import com.rabbitmq.client.Channel;
    import com.rabbitmq.client.Connection;
    import com.rabbitmq.client.DefaultConsumer;
    import com.rabbitmq.client.Envelope;
    import com.rabbitmq.client.AMQP.BasicProperties;
    import com.toov5.utils.MQConnectionUtils;
    
    public class Consumer {
      
         //队列名称
            private static final String QUEUE_NAME = "test_queue";
            
            public static void main(String[] args) throws IOException, TimeoutException {
                System.out.println("消费者启动..........");
                //创建新的连接
            Connection connection = MQConnectionUtils.newConnection();
               //创建Channel
                Channel channel = connection.createChannel();
                // 消费者关联队列
                channel.queueDeclare(QUEUE_NAME, false, false, false, null);
                
                  DefaultConsumer defaultConsumerr = new DefaultConsumer(channel) {
                      //监听获取消息
                        @Override
                        public void handleDelivery(String consumerTag, Envelope envelope, BasicProperties properties,
                                byte[] body) throws IOException {
                            String msg =new String(body,"UTF-8");
                            System.out.println("消费者获取生产者消息："+msg);
                        }
                  };
                //牵手模式设置  默认自动应答模式  true:自动应答模式  
                  channel.basicConsume(QUEUE_NAME, true, defaultConsumerr);              
                  
    //            //关闭通道和连接
    //             channel.close();
    //             connection.close();
            }
    }

运行后的结果：
