 spring cloud 中zuul智能路由,本地部署沒有問題,部署到服務器就報com.netflix.zuul.exception.ZuulException: Forwarding error

項目中用到spring cloud+docker,各個組件本地部署沒有,一部署在服務器就出現問題,報如下的錯誤

com.netflix.zuul.exception.ZuulException: Forwarding error

從網上找各種資源都沒找到,包括找springcloud 開源社區發帖

 

關鍵在於-----

在配置文件加入

eureka:
  client:
    serviceUrl:
      defaultZone: http://XXX:8080/eureka/
#這里才是關鍵
    fetch-registry: true
    register-with-eureka: true

 

 

#服務注冊中心實例的主機名

eureka.instance.hostname=localhost

#是否向服務注冊中心注冊自己

eureka.client.register-with-eureka=true

#是否檢索服務

eureka.client.fetch-registry=true
