zuul无法使用动态端口微服务路由

我有一个动态端口的微服务,即, server.port=0 是的。 微服务正在尤里卡注册罚款,它正在运行。

但是,当我试图通过Zuul网关访问它时,它无法处理我的Zuul网关中的以下日志。

c.netflix.loadbalancer.BaseLoadBalancer  : Client: book instantiated a LoadBalancer: DynamicServerListLoadBalancer:{NFLoadBalancer:name=book,current list of Servers=[],Load balancer stats=Zone stats: {},Server stats: []}ServerList:null

但是,当我更改微服务的端口时( book )到非动态 server.port = 8081 ,一切运行良好,每次我也必须重新启动zuul应用程序。 我想当其中一个微服务更改端口时,情况不太好。

让我分享 application.yml 两个文件的内容。

微服务(书籍) 应用程序.yml

spring:
  application:
    name: book

server:
  port: 0 # I change it between 0 and 8081 (8081 works like a charm)

eureka:
  client:
    service-url:
      defaultZone: ${EUREKA_URI:http://localhost:8761/eureka}
  instance:
    prefer-ip-address: true

祖鲁 应用程序.yml

server:
  port: 8080
spring:
  application:
    name: gatekeeper

zuul:
  routes:
    book: 
      serviceId: book

#Added it so as to increase the timeout for the underlying hysterix of the zuul

hystrix:
  command:
    default:
      execution:
        isolation:
          strategy: THREAD
          thread:
            timeoutInMilliseconds: 60000

尤里卡服务器 应用程序.yml

server:
  port: 8761

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