bootstrap.yml的配置文件

spring:
  application:
    name: order
  cloud:
    config:
      discovery:
        enabled: true
        service-id: CONFIG
      profile: dev
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/

配置文件order-dev.yml可以访问到，eureka中config的id就是CONFIG没有问题。
当按照课程一步步来，bootstrap.yml启动报错

我一直觉得bootstrap.yml里面格式的问题，到资料中，把配置文件拉了下来，去掉其他配置，启动还是一样的。实在是找不到问题咯，师兄帮忙看看。
