configservice
需要加入EnableConfigServer注解。
package com.liumiaocn.demo.springcloud;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.config.server.EnableConfigServer;import org.springframework.cloud.netflix.eureka.EnableEurekaClient;@SpringBootApplication@EnableConfigServer@EnableEurekaClientpublic class ConfigserviceApplication { public static void main(String[] args) { SpringApplication.run(ConfigserviceApplication.class, args); }}

| 项目 | 详细 |
|---|---|
| server.port | configService提供服务所用Port |
| spring.application.name | 向Eureka Server进行注册时使用的服务名 |
| eureka.client.serviceUrl.defaultZone | http://localhost:8801/eureka/ 注意此处的８８０１端口号需要跟Server端一致。 |
| spring.profiles.active | spring cloud config支持本地/svn/git，设定为native表示为本地方式 |
生成Package
| 项目 | 详细 |
|---|---|
| 命令 | mvn clean package |
| 执行场所 | pom所在目录 |
| 目标文件所在目录 | 工程根目录下Target |
| 目标文件名称 | configservice-0.0.1-SNAPSHOT.jar |
orgservice的设定文件
为orgservice准备如下两个设定文件分别对应于dev环境和test环境
orgservice-dev.properties
demo.word=hellodev
- 1
orgservice-test.properties
demo.word=hellotest
- 1
启动
＞启动各个服务后，也启动configservice
Eureka确认
orgservice设定文件确认
| 项目 | 访问方法（ＵＲＬ） |
|---|---|
| orgservice dev | http://localhost:8888/orgservice/dev |
| orgservice test | http://localhost:8888/orgservice/test |

| server.port | orgService提供服务所用Port |
| spring.application.name | 向Eureka Server进行注册时使用的服务名 |
| eureka.client.serviceUrl.defaultZone | http://localhost:8801/eureka/ 注意此处的８８０１端口号需要跟Server端一致。 |
| spring.cloud.config.profile | 选择了服务器侧的orgservice-test.properties作为配置设定文件 |
| spring.cloud.config.uri | 服务器侧的URI，此处为http://localhost:8888/ |
Demo代码
为了验证真正读入了服务器侧的设定文件，我们使用Spring的Value注解读入设定文件中的demo.word
package com.liumiaocn.demo.springcloud;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.netflix.eureka.EnableEurekaClient;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@SpringBootApplication@RestController@RequestMapping("/org")@EnableEurekaClientpublic class OrgserviceApplication { @Value("${demo.word:default-value}") String strDemoWord; @RequestMapping("/detail") public String Detail(){ return "## The detail information about: Organization : with demo word: "+strDemoWord; } public static void main(String[] args) { SpringApplication.run(OrgserviceApplication.class, args); }}

总结
＞本文介绍了Spring Cloud Config的Server端和Client端如何使用，至次，通读这六篇文章，大体一个小时时间，对有spring基础的初学者应该能够执行搭建结合了Eureka/Zuul/Hystrix/Spring Cloud Config等常用组件进行Sample工程的搭建和基础入门。
但是为了简单起见，比如设定文件只是使用了application.properties，能够不设定大体能运行的选项基本都没有设定，如何更好的设计和搭建分布式的微服务架构，在其他的文章中我们会继续讨论。
