准备3个配置文件，并push到github：

配置：application.yml

server:
      port: 3344
    
    spring:
      application:
        name: cloud-config-center #注册进eureka的微服务名
      cloud:
        config:
          server:
            git:
              uri: git@github.com:xxxx/springcloud-config.git
              search-paths:
                - springcloud-config #指定搜索目录
          label: master #读取分支
    
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:7001/eureka

启动类：

@SpringBootApplication
    @EnableConfigServer
    public class MainAppConfigCenter3344 { 
        public static void main(String[] args) { 
            SpringApplication.run(MainAppConfigCenter3344.class, args);
        }
    }

**测试：**  
启动eureka，再启动3344配置中心：

访问：`localhost:3344/master/config-dev.yml`

访问：`localhost:3344/master/config-test.yml`

### 配置文件读取规则 ###

**/\{label\}/\{application\}-\{profile\}.yml** 示例：

*  master分支

http://config-3344.com:3344/master/config-dev.yml
    http://config-3344.com:3344/master/config-test.yml
    http://config-3344.com:3344/master/config-prod.yml

*  dev分支

http://config-3344.com:3344/dev/config-dev.yml
    http://config-3344.com:3344/dev/config-test.yml
    http://config-3344.com:3344/dev/config-prod.yml

**/\{application\}-\{profile\}.yml** 示例

http://config-3344.com:3344/config-dev.yml
    http://config-3344.com:3344/config-test.yml
    http://config-3344.com:3344/config-prod.yml
    http://config-3344.com:3344/config-xxx.yml(不存在，返回  {}  )

默认找master分支，也可以在配置文件中指定label属性修改

**/\{application\}/\{profile\}\[/\{label\}\]** 示例

http://config-3344.com:3344/config/dev/master
    http://config-3344.com:3344/config/test/master
    http://config-3344.com:3344/config/prod/master

注意：该方式返回为JSON
