### 失敗響應
spring.cloud.config.fail-fast=true
####引入aop  retry依賴
####最大重試次數 默認6次
spring.cloud.config.retry.max-attempts= 6
####最大重試時間間隔
spring.cloud.config.retry.max-interval= 2000
#####初始重試間隔 默認1000
spring.cloud.config.retry.initial-interval = 1500
##### 下一次間隔係數
spring.cloud.config.retry.multiplier= 1.2

####開啓自動刷新  引入actuator 依賴




####  感覺有bug  待後續解決 屬性註冊不成功，將config-server 項目註冊爲默認 configserver可行。
#spring.cloud.config.discovery.serviceid = config-server
