	public static void main(String[] args) {

}

 

#注册中心地址配置
eureka:
    client:
        serviceUrl:
            defaultZone: http://localhost:8761/eureka/
#服务提供方端口号            
server:
    port: 8762
spring:
    application:
    	#服务提供方名称   
        name: service-helloworld

 

2.启动服务提供方，在注册中心查询application，访问服务方接口，打印服务方端口号
