### SpringCloud Config配置实例 ###

#### Git配置文件本地配置 ####

在本地D:\\44\\mySpringCloud\\microservicecloud-config路径下新建文件  
microservicecloud-config-eureka-client.yml

microservicecloud-config-eureka-client.yml内容：

spring: 
      profiles: 
        active: 
          - dev
    ---
    server: 
      port: 7001 #注册中心占用7001端口,冒号后面必须要有空格
    
    spring: 
      profiles: dev
      application:
        name: microservicecloud-config-eureka-client
    
    eureka: 
      instance: 
        hostname: eureka7001.com #冒号后面必须要有空格
      client: 
        register-with-eureka: false #当前的eureka-server自己不注册进服务列表中
        fetch-registry: false #不通过eureka获取注册信息
        service-url: 
          defaultZone: http://eureka7001.com:7001/eureka/
    ---
    server: 
      port: 7001 #注册中心占用7001端口,冒号后面必须要有空格
    
    spring: 
      profiles: test

#### 测试 ####

test配置默认访问，http://localhost:8001/dept/list

可以看到数据库配置是02
