spring配置文件

server.port=8882
spring.config.name=client

bootstrap.yml

spring.cloud.config.uri=http://127.0.0.1:8881
spring.cloud.config.label=master
spring.cloud.config.profile=pro
spring.application.name=application

 客户端入口

package com.zcj;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@SpringBootApplication
public class ConfigClientApplication {
	@Value("${zcj.name}")
	private String zcj;
	public static void main(String[] args) {
		SpringApplication.run(ConfigClientApplication.class, args);
	}
	@RequestMapping("zcj")
	public String zcj(){
		return "zcj.name="+zcj;
	}
}

 运行结果

git:

https://github.com/zhoucanji/config-repo/blob/master/application-pro.properties

 https://github.com/zhoucanji/config-repo/blob/master/application.properties

查看服务端获取到的git的配置文件

http://127.0.0.1:8881/master/application-pro.properties 

 http://127.0.0.1:8881/master/application-default.properties

 http://127.0.0.1:8881/application/pro/master

 http://127.0.0.1:8881/application/default/master

如果客户端bootstrap.properties中spring.cloud.config.profile=pro

 如果客户端bootstrap.properties中spring.cloud.config.profile=default

总结:

• config-server 配置服务端，服务管理配置信息
• config-client 客户端，客户端调用server端暴露接口获取配置信息
