Eureka啓動報錯Cannot execute request on any known server

使用配置中心配置eureka服務端的時候，啓動服務以後一直報錯Cannot execute request on any known server，網上查了一下原因：沒有配置eureka.client.registerWithEureka=false和eureka.client.fetchRegistry=false

spring:
  profiles:
    active:
    - dev
---
server:
  port: 7001
spring:
  profiles: dev
  application: 
    name: mycloud-config-eureka-client

eureka:
  instance:
    hostname: eureka7001.com
    client:
      register-with-eureka: false 
      fetch-registry: false  
      service-url:
        defaultZone: http://eureka7001.com:7001/eureka/

由於這段配置沒有生效，client應該和instance對齊

client:
      register-with-eureka: false
      fetch-registry: false 

改成

spring:
  profiles:
    active:
    - dev
---
server:
  port: 7001
spring:
  profiles: dev
  application: 
    name: mycloud-config-eureka-client

eureka:
  instance:
    hostname: eureka7001.com
  client:
    register-with-eureka: false 
    fetch-registry: false  
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka/
