###服务名称(服务注册到eureka名称)
spring:
   application:
       name: test-configClient #如果配置了Config，该名称必须跟Git上的配置文件前缀一致。如：test-configClient-prd.properties
   cloud:
     config:
       # 读取版本环境，也就是配置文件的后缀名。如：test-configClient-prd.properties
       profile: prd
       discovery:
         # 就是读取configserver服务，写成configserver的spring.application.name
         service-id: config-server
         enabled: true
###服务启动端口号
server:
   port: 8087
###服务注册到eureka地址
eureka:
 client:
   service-url:
     defaultZone: http://localhost:8100/eureka
