spring cloud 搭建（配置中心）

创建配置中心：

选择Spring Initializr模板

选择Config Server

pom文件

</project>

添加服务注解：

@EnableConfigServer
@EnableEurekaClient

创建配置文件（切换配置文件的示例，在这里一并展示）

config文件夹：

dev：测试环境

prod：正式环境

config-dev.yml

registry:
  url: http://${host:localhost}:9010/eureka/

# 测试属性
isDebug: true

config-prod.yml

registry:
  url: http://${host:localhost}:9010/eureka/

# 测试属性
isDebug: false

bootstrap.yml

spring:
  application:
    name: cloud.config
  profiles:
    #native表示本地方式
    active: native
  cloud:
    config:
      server:
        native:
          # 配置文件存放路径
          search-locations: classpath:/config/

application.yml

server:
  port: 9020

eureka:
  client:
    service-url:
      defaultZone: http://localhost:9010/eureka/
