<dependency>

<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>

yml
server:
port: 7001
eureka.client.serviceUrl.defaultZone: http://localhost:8761/eureka/
spring:
application.name: eureka-client
啓動類添加註解:
@EnableEurekaClient @EnableDiscoveryClient
spring cloud中discovery service有許多種實現(eureka、consul、zookeeper等等),@EnableDiscoveryClient基於spring-cloud-commons, @EnableEurekaClient基於spring-cloud-netflix。
其實用更簡單的話來說,就是如果選用的註冊中心是eureka,那麼就推薦@EnableEurekaClient,如果是其他的註冊中心,那麼推薦使用@EnableDiscoveryClient。
