yml配置

spring:
application:
name: eureka-server
server:
port: 8888
eureka:
instance:
#    注册到eurekaip地址
hostname: 127.0.0.1
client:
service-url:

dedaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
#      因为自己是注册中心  不需要注册自己
register-with-eureka: false
#      因为自己是注册中心,不需要检索服务
fetch-registry: false

启动类

package eureka;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
//开启注册中心server
@EnableEurekaServer
public class EurekaServerApp {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApp.class,args);
}
}
