2创建microservicecloud-config-eureka-client-7001客户端，并测试

/**
 * EurekaServer服务器端启动类,接受其它微服务注册进来
 * 
 * @author zhouyang
 */
@SpringBootApplication
@EnableEurekaServer
public class Config_Git_EurekaServerApplication
{
	public static void main(String[] args)
	{
		SpringApplication.run(Config_Git_EurekaServerApplication.class, args);
	}
}

application.yml

spring:
  application:
    name: microservicecloud-config-eureka-client

bootstrap.yml

spring: 
  cloud: 
    config: 
      name: microservicecloud-config-eureka-client     #需要从github上读取的资源名称，注意没有yml后缀名
      profile: dev 
      label: master 
      uri: http://config-3344.com:3344      #SpringCloudConfig获取的服务地址

测试1

启动microservicecloud-config-3344

启动microservicecloud-config-eureka-client-7001

说明：如果启动成功，microservicecloud-config-eureka-client-7001会从配置中心读取配置文件，就会出现下面的情况

http://eureka7001.com:7001/

3创建microservicecloud-config-dept-client-8001客户端，并测试

代码是对原有的microservicecloud-provider-dept-8001的拷贝，就是配置改了下


@SpringBootApplication
@EnableEurekaClient //本服务启动后会自动注册进eureka服务中
@EnableDiscoveryClient //服务发现
public class DeptProvider8001_Config_App
{
	public static void main(String[] args)
	{
		SpringApplication.run(DeptProvider8001_Config_App.class, args);
	}
}
