**构建config client**

首先在父模块下，创建一个名称为config-client，pom.xml文件配置如下：

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
            <version>2.0.4.RELEASE</version>
        </dependency>
    </dependencies>

创建bootstrap.yml 文件，配置如下：

server:
      port: 8881
    
    spring:
      application:
        name: config-client
      cloud:
        config:
          uri: http://localhost:8888/
          label: master
          profile: dev

*  spring.cloud.config.label \#指明远程仓库的分支
 *  spring.cloud.config.profile \#项目环境标识
 *  dev开发环境配置文件
 *  test测试环境
 *  pro正式环境
 *  spring.cloud.config.uri= http://localhost:8888/ \#指明配置服务中心的网址。

程序的入口类，写一个API接口“／hello”，返回从配置中心读取的user.name变量的值，代码如下：

@RestController
    @SpringBootApplication
    public class Application {
    public static void main(String[] args) {
    	SpringApplication.run(Application.class, args);
    }
    
        @Value("${user.name}")
        String name;
    
        @RequestMapping(value = "/hello")
        public String hi(){
            return "hello," + name;
        }
    }

分别启动config-server和config-client服务，在浏览器中访问[http://localhost:8881/hello][http_localhost_8881_hello]如下：

hello,zhangsan

这就说明，config-client从config-server获取了user.name的属性，而config-server是从git仓库读取的,如图：
