</project>

bootstrap.yml 文件（只能是bootsrap.yml 不可以是application.yml）

server:
  port: 9001
spring:
  application:
    name: zuul
  cloud:
    bus:
      refresh:
        enabled: true
      trace:
        enabled: true
    config:
      uri: http://localhost:8001
      profile: dev
  rabbitmq:
    host: localhost
    port: 5672
    username: guest
    password: guest
    virtual-host: guest-v

三、安装rabbitmq

docker run -d --name rabbitmq3.8.5 -p 5672:5672 -p 15672:15672 -v `pwd`/data:/var/lib/rabbitmq --hostname myRabbit -e RABBITMQ_DEFAULT_VHOST=my_vhost  -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin 181d2227d92f

记的要给 用户分配 virtual hosts

四、对动态修改的配置
1、git 上添加webhook
2、引用资源的地方加注解@RefreshScope

五、动态修改数据库参考
