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
