spring cloud Bug之was unable to refresh its cache! status = Cannot execute request on any known server

可能原因:

1.application.yml

server:
  port: 10001
spring:
  application:
    name: microservice-consumer-movie
eureka:
  instance:
      hostname:
      prefer-ip-address: true
  client:
    serviceUrl:
      defaultZone: http://user:123@localhost:8761/eureka/
注意:
serviceUrl不能寫成service-url
defaultZone不能寫成default-zone
要不然可能會出現未知的錯誤.改成我上面這樣就行了.
defaultZone的值需要改成你自己的eureka注冊中心地址.
2.此問題或許可能出現其他的異常,所以要注意.
