###eureka管理
eureka.client.serviceUrl.defaultZone=http://pear1:9998/eureka/
spring.cloud.config.discovery.enabled = true

### 失败响应
spring.cloud.config.fail-fast=true
####引入aop  retry依赖
####最大重试次数 默认6次
spring.cloud.config.retry.max-attempts= 6
####最大重试时间间隔
spring.cloud.config.retry.max-interval= 2000
#####初始重试间隔 默认1000
spring.cloud.config.retry.initial-interval = 1500
##### 下一次间隔系数
spring.cloud.config.retry.multiplier= 1.2

####开启自动刷新  引入actuator 依赖




####  感觉有bug  待后续解决 属性注册不成功，将config-server 项目注册为默认 configserver可行。
#spring.cloud.config.discovery.serviceid = config-server

####关闭授权
management.security.enabled=false
