RabbitMq简单模式下生产者与消费者的实现

首先需要导入对应的依赖

    
        
            com.rabbitmq
            amqp-client
            5.6.0
        
    

依赖导入完毕后，首先实现生产者

    public static void main(String[] args) throws IOException, TimeoutException {
         //1.创建连接工厂
        final ConnectionFactory factory = new ConnectionFactory();

        //2.设置参数
        factory.setHost("127.0.0.1");
        factory.setPort(5672);
        factory.setVirtualHost("admin");
        factory.setUsername("admin");
        factory.setPassword("admin");
        //3.创建连接connection
        final Connection connection = factory.newConnection();
        //4.创建channel
        final Channel channel = connection.createChannel();
        //创建队列
        
         channel.queueDeclare("hello_world",true,false,false,null);
        //发送消息
        

        String body = "hello consumer";

        channel.basicPublish("","hello_world",null,body.getBytes());

        channel.close();
        connection.close();
    }

其次：实现消费者

public static void main(String[] args) throws IOException, TimeoutException {
                     //1.创建连接工厂
        final ConnectionFactory factory = new ConnectionFactory();

        //2.设置参数
        factory.setHost("127.0.0.1");
        factory.setPort(5672);
        factory.setVirtualHost("admin");
        factory.setUsername("admin");
        factory.setPassword("admin");
        //3.创建连接connection
        final Connection connection = factory.newConnection();
        //4.创建channel
        final Channel channel = connection.createChannel();
        //创建队列
        
         channel.queueDeclare("hello_world",true,false,false,null);

         channel.basicConsume("hello_world",true,new DefaultConsumer(channel) {
             //回调方法

             
             @Override
             public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
//                 super.handleDelivery(consumerTag, envelope, properties, body);
                 System.out.println("consumerTag==========》》》》"+consumerTag);
                 System.out.println("Exchange=========>>>>>>>"+envelope.getExchange()+"=====rount======>>>"+envelope.getRoutingKey());
                 System.out.println("properties================>>>"+properties.getMessageId());
                 System.out.println("body=============>>>>>>>>>"+ new String(body));
             }

         });
    }

首先启动生产者将消息发送到mq，接着启动消费者读取消息

至此，rabbitMq简单模式就实现了
