server

1. 创建保存配置文件的git仓库
   https://gitee.com/jiyangM/spring-cloud-config/tree/master/config

2. 添加配置文件
   

3. server端代码
   pox.xml

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-server</artifactId>
    </dependency>
</dependencies>

配置文件application.yml

server:
  port: 8888

spring:
  cloud:
    config:
      server:
        git:
          uri: https://gitee.com/jiyangM/spring-cloud-config
          search-paths: config
          username: [e-mail]
          password: 1993Jiyang

/**
 * Created by jiyang on 15:16 2017/12/15
 */
@SpringBootApplication
@EnableConfigServer
public class Application {

    /**
     * application.java 文件不能直接放在main/java文件夹下，必须要建一个包把他放进去
     * @param args
     */
    public static void main(String[] args){
        SpringApplication.run(Application.class,args);
    }
}

启动，测试，访问 ：
http://localhost:8888/neo-config/test
会返回配置信息。

注意： neo-config/test 对应git仓库中的neo-config-test.yml文件
