RabbitMQ之Fanout交换器模式开发

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

 spring.application.name=provider
 spring.rabbitmq.host=192.168.50.30
 spring.rabbitmq.port=5672
 spring.rabbitmq.username=rabbit
 spring.rabbitmq.password=rabbit
 #设置交换器的名称
 mq.config.exchange=order.fanout

代码

 @Component
 public class Sender {
     @Autowired
     private AmqpTemplate amqpTemplate;

     @Value("${mq.config.exchange}")
     private String exchange;

     public void send(String msg){
         this.amqpTemplate.convertAndSend(this.exchange, "", msg);
     }
 }

二、Consumer

配置文件

 spring.application.name=consumer
 spring.rabbitmq.host=192.168.50.30
 spring.rabbitmq.port=5672
 spring.rabbitmq.username=rabbit
 spring.rabbitmq.password=rabbit
 #设置交换器的名称
 mq.config.exchange=order.fanout
 #短信服务队列名称
 mq.config.queue.sms=order.sms
 #push 服务队列名称
 mq.config.queue.push=order.push

代码

SmsReceiver

 /**
     @RabbitListener bindings:绑定队列
     @QueueBinding value:绑定队列的名称
         exchange:配置交换器
         key:路由键
     @Queue value:配置队列名称
         autoDelete:是否是一个可删除的临时队列
     @Exchange value:为交换器起个名称
         type:指定具体的交换器类型
 */
 @Component
 @RabbitListener(
     bindings=@QueueBinding(
         value=@Queue(
             value="${mq.config.queue.sms}",
             autoDelete="true"
         ),
         exchange=@Exchange(
             value="${mq.config.exchange}",
             type=ExchangeTypes.FANOUT
         )
     )
 )
 public class SmsReceiver {
     @RabbitHandler
     public void process(String msg) {
         System.out.println(msg);
     }
 }

PushReceiver

 /**
     @RabbitListener bindings:绑定队列
     @QueueBinding value:绑定队列的名称
             exchange:配置交换器
     @Queue value:配置队列名称
             autoDelete:是否是一个可删除的临时队列
     @Exchange value:为交换器起个名称
         type:指定具体的交换器类型
 */
 @Component
 @RabbitListener(
     bindings=@QueueBinding(
         value=@Queue(
             value="${mq.config.queue.push}",
             autoDelete="true"),
         exchange=@Exchange(
             value="${mq.config.exchange}",
             type=ExchangeTypes.FANOUT
         )
     )
 )
 public class PushReceiver {
     @RabbitHandler
     public void process(String msg){
         System.out.println("Push receiver: " + msg);
     }
 }
