RabbitMQ之Fanout交换器模式开发

Posted 2022-01-11 guanghe

Fanout模式，即广播模式，一个发送到交换机的消息会被转发到与该交换机绑定的所有队列上。

一、Provider

配置文件

1 spring.application.name=provider
2 spring.rabbitmq.host=192.168.50.30
3 spring.rabbitmq.port=5672
4 spring.rabbitmq.username=rabbit
5 spring.rabbitmq.password=rabbit
6 #设置交换器的名称
7 mq.config.exchange=order.fanout

代码

 1 @Component
 2 public class Sender 
 3     @Autowired
 4     private AmqpTemplate amqpTemplate;
 5 
 6     @Value("$mq.config.exchange")
 7     private String exchange;
 8 
 9     public void send(String msg)
10         this.amqpTemplate.convertAndSend(this.exchange, "", msg);
11     
12 

二、Consumer

配置文件

 1 spring.application.name=consumer
 2 spring.rabbitmq.host=192.168.50.30
 3 spring.rabbitmq.port=5672
 4 spring.rabbitmq.username=rabbit
 5 spring.rabbitmq.password=rabbit
 6 #设置交换器的名称
 7 mq.config.exchange=order.fanout
 8 #短信服务队列名称
 9 mq.config.queue.sms=order.sms
10 #push 服务队列名称
11 mq.config.queue.push=order.push

代码

SmsReceiver

 1 /**
 2     @RabbitListener bindings:绑定队列
 3     @QueueBinding value:绑定队列的名称
 4         exchange:配置交换器
 5         key:路由键
 6     @Queue value:配置队列名称
 7         autoDelete:是否是一个可删除的临时队列
 8     @Exchange value:为交换器起个名称
 9         type:指定具体的交换器类型
10 */
11 @Component
12 @RabbitListener(
13     bindings=@QueueBinding(
14         value=@Queue(
15             value="$mq.config.queue.sms",
16             autoDelete="true"
17         ),
18         exchange=@Exchange(
19             value="$mq.config.exchange",
20             type=ExchangeTypes.FANOUT
21         )
22     )
23 )
24 public class SmsReceiver 
25     @RabbitHandler

 1 /**

 6             autoDelete:是否是一个可删除的临时队列
 7     @Exchange value:为交换器起个名称

16         exchange=@Exchange(

19         )
20     )
21 )
22 public class PushReceiver 
23     @RabbitHandler
24     public void process(String msg)
25         System.out.println("Push receiver: " + msg);
