### SpringCloud Config服务端配置 ###

用自己的GitHub账号在GitHub上新建一个名为microservicecloud-config  
的新Repository：

获取Repository的http链接

本地硬盘目录上新建git仓库并clone：

在本地D:\\44\\mySpringCloud\\microservicecloud-config里面新建一个application.yml：

spring:
      profiles:
        active:
          - dev
    
    ---
    spring:
      profiles: dev # 开发环境
      application:
        name: microservicecloud-config-zhang-dev
    ---
    spring:
      profiles: test # 测试环境
      application:
        name: microservicecloud-config-zhang-test

将上一步的YML文件推送到github上：

*  git add .
 *  git commit -m “init yml”
 *  git push origin master

新建Module模块microservicecloud-config-3344  
它即为Cloud的配置中心模块：  
引入依赖：

application.yml

server:
      port: 3344
    
    spring:
      application:
        name: microservicecloud-config
      cloud:
        config:
          server:
            git:
              uri: https://github.com/xxx/microservicecloud-config.git #github仓库名字

主启动类Config\_3344\_StartSpringCloudApp：

@SpringBootApplication
    @EnableConfigServer
    public class Config_3344_StartSpringCloudApp { 
        public static void main(String[] args) { 
            SpringApplication.run(Config_3344_StartSpringCloudApp.class, args);
        }
    }

修改hosts文件，增加映射：

127.0.0.1  config-3344.com

测试通过Config微服务是否可以从GitHub上获取配置内容：

启动微服务3344：
