Fanout

====================================================================

FanoutExchange 的数据交换策略是把所有到达 FanoutExchang 的消息转发给所有与它绑定的Queue ，在这种策略中， routingkey 将不起任何作用.

1.创建消费者

项目结构

配置文件

spring.application.name=springcloud-mq

spring.rabbitmq.host=192.168.88.150

spring.rabbitmq.port=5672

spring.rabbitmq.username=dpb

spring.rabbitmq.password=123

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

两个消费者

@Component

@RabbitListener(

bindings=@QueueBinding(

value=@Queue(value="${mq.config.queue.sms}",autoDelete=“true”),

exchange=@Exchange(value="${mq.config.exchange}",type= ExchangeTypes.FANOUT)

)

)

public class SmsReciver {

@RabbitHandler

public void process(String msg){

System.out.println("Sms…receiver: "+msg);

}

}

@Component

@RabbitListener(

bindings=@QueueBinding(

value=@Queue(value="${mq.config.queue.push}",autoDelete=“true”),

exchange=@Exchange(value="${mq.config.exchange}",type= ExchangeTypes.FANOUT)

)

)

public class PushReciver {

@RabbitHandler

public void process(String msg){

System.out.println("Push…receiver: "+msg);

}

}

启动后等待接收消息即可~

2.创建订单服务

项目结构

配置文件

spring.application.name=springcloud-mq
