添加服务注解：@EnableEurekaServer

 

application.yml

server:
  port: 9010 #端口
 
eureka:
   server:
      enable-self-preservation: false  # 设为false，关闭自我保护，会清理无效节点 
      eviction-interval-timer-in-ms: 30000  # 清理无效节点间隔时间（单位毫秒，默认是60*1000）
   instance:
       hostname: 127.0.0.1
       preferIpAddress: true
   client:
       registerWithEureka: false #注册中心，无需注册自己
       fetchRegistry: false
       serviceUrl: #演示调用的配置
           defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
 

 

启动：http://localhost:9010/
