import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
/** 服务注册 */
@EnableEurekaServer

# eureka实例端口
server:
   port: 8761
   
# eureka注册中心服务器配置   
eureka:
   instance:
       # eureka实例IP地址	
       hostname: localhost
   client:
       # eureka实例是否注册自己,默认是 true
       registerWithEureka: false
       # eureka实例发现注册自己,默认是 true
       fetchRegistry: false
       serviceUrl:
       	   # 指定eureka注册中心服务器的地址
           defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
