  • RabbitMQ入门Demo

    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

    这次我们关掉Receive,再次运行Send,然后点击管理网页上的Queue。 

    点击hello进去,并点击Get Message,可以看到Hello World消息的确已经传送到RabbitMQ的服务器端了
