SpringCloud 实战二十三：服务配置动态刷新-自动版-消息总线

1、3344服务配置中心添加rabbitmq支持

<!--     添加消息总线rabbitMq支持   -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bus-amqp</artifactId>
</dependency>

2、配置

rabbitmq:
  host: 47.56.236.87
  port: 5672
  username: guest
  password: guest

# rabbitmq相关配置，暴露bus刷新端点
management:
  endpoints:
    web:
      exposure:
        include: "bus-refresh"
