 错误原因：

 Eureka作为注册中心，如果本身宕机会导致所有的服务都无法使用，所以Eureka也要搭建自己的集群，既然要搭建集群，那么集群之间也需要相互通信，Eureka通信靠的就是Eureka-client，也即作为服务端的同时也是客户端，将来Eureka之间要进行相互注册，由于没有client可以注册，所以就有了上述错误。

解决方案：

让它自己注册到自己，也就是告诉Eureka注册地址，在yml中配置即可

 

注：在启动过程中依然会报错，因为在启动过程中会去配置的地址中注册，此时项目本身还未启动完成，无法注册，启动完成后就不会报错了。

server:
  port: 9091
eureka:
  client:
    # service-url是一个map集合而不是一个字符串，所以需要key与value，不能简单写url
    service-url:
      defaultZone: http://127.0.0.1:9091/eureka

注册中心 的本身服务名为：UNKNOWN

上述问题解决后启动在Eureka中心的Instances currently registered with Eureka中发现本身服务应用名为UNKNOWN，是因为没有配置本身的应用名，在yml文件中配置即可

spring:
  application:
    name: eureka-server
