application.yml文件

server:
  port: 8761
eureka:
  client:
    service-url:
     defaultZone: http://localhost${server.port}/eureka
    register-with-eureka: false
    fetch-registry: false

Springboot入口加上注解

@EnableEurekaServer

就可以正常启动了。下面是我遇到的坑

这个问题我的解决方式：我之前使用的springboot版本是2.0.2，我将springboot版本改为1.5.9后会报这个错误

Exception in thread "main" java.lang.NoSuchMethodError: org.springframework.boot.SpringApplication.run(Ljava/lang/Class;[Ljava/lang/String;)Lorg/springframework/context/ConfigurableApplicationContext;
	at com.example.democloud.DemoCloudApplication.main(DemoCloudApplication.java:12)
但是，清空一下maven之后，重启项目，就可以了
