1、从github上下载最新版本
spring-cloud-config
2、编译并运行spring-cloud-config-server
cd spring-cloud-config-server
../mvnw spring-boot:run
如果运行mvnw遇到下面的错误，用vi处理一下就好了
/bin/sh^M: bad interpreter: No such file or directory
用vi处理一下
:set fileformat=unix
3、默认端口为8888，默认配置仓库为github
config-repo
支持以下访问语法：
#获取配置
/{application}/{profile}[/{label}]
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
#更新Environment、重新绑定@ConfigurationProperties、重置日志级别
/env
#刷新@RefreshScope
/refresh
#重启Spring上下文，默认是禁用的
/restart` for restarting the Spring context (disabled by default)
#调用ApplicationContext的stop及start等生命周期相关函数
/pause
/resume
我们来测试一下服务端运行情况：（服务端要可以连接到github上哦）
#foo.properties
curl localhost:8888/foo-master.properties
#foo.properties tag=v1.0.0.RC2
curl localhost:8888/v1.0.0.RC2/foo-master.properties
#foo-development.properties
curl localhost:8888/foo-development.properties
#foo-db.properties
curl localhost:8888/foo-db.properties
#foo-development-db.properties
curl localhost:8888/foo-development-db.properties
4、看一下自带的例子
spring-cloud-config-sample/src/main/java/sample/Application.java
package sample;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.core.env.Environment;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@SpringBootApplication
public class Application {
@Autowired
private Environment environment;
@Value("${spring.application.name}")
private String appName;
@RequestMapping("/appName")
public String appName() {
return appName;
}
@RequestMapping("/")
public String query(@RequestParam("q") String q) {
return environment.getProperty(q);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
5、测试一下例子
cd spring-cloud-config-sample
mvn spring-boot:run
6、看一下输出信息

7、测试一下
curl localhost:8080/?q=foo
8、是不是很简单，到自己的项目上试试吧
