## 表示消费者消费成功消息以后需要手工的进行签收(ack),默认为auto
spring.rabbitmq.listener.simple.acknowledge-mode=manual
spring.rabbitmq.listener.simple.concurrency=5
spring.rabbitmq.listener.simple.max-concurrency=10
spring.rabbitmq.listener.simple.prefetch=1
## 作业:
## 最好不要在代码里写死配置信息,尽量使用这种方式也就是配置文件的方式
## 在代码里使用 ${} 方式进行设置配置: ${spring.rabbitmq.listener.order.exchange.name}
spring.rabbitmq.listener.order.exchange.name=order-exchange
spring.rabbitmq.listener.order.exchange.durable=true
spring.rabbitmq.listener.order.exchange.type=topic
spring.rabbitmq.listener.order.exchange.key=order.*
