启动类：

package com.forezp;

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

@EnableEurekaClient

public class ConfigServerApplication {

    public static void main(String[] args) {

        SpringApplication.run(ConfigServerApplication.class, args);

    }

}

controller类：

package com.forezp.controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

/*

 * 启动config client之前，要先访问config server端的任意url，要不然config client启动失败，报错为某个值@Value注入失败，原因不明。

 *

 */

@RestController

public class ConfigServerController {

    public String hi(){

        return "Hi this is Config Server!";

    }

 * 4、http://localhost:8002/hi  获取新的foo值
