Eureka的客户端启动报错Cannot execute request on any known server

贴上完整报错代码如下

下面是我的配置文件信息:

server:
  port: 8761

spring:
  profiles: peer1
eureka:
  instance:
    hostname: peer1
  client:
    serviceUrl:
      defaultZone: http://peer2:8769/eureka/

错误找了很久都没有找到,最后发现是版本的问题,我用的springboot版本是最低版本所以配置文件稍微修改一下如下:

server:
  port: 8761

spring:
  profiles: peer1
eureka:
  instance:
    hostname: peer1
  client:
    serviceUrl:
      default-zone: http://peer2:8769/eureka/

注意: defaultZone 改成了 default-zone
