Eureka -无法获得响应-无法联系任何eureka节点

Question

我有一个eureka服务器在端口8761 (localhost:8761/ Eureka )上运行，我有一个Zuul应用程序，我想向eureka注册，但我一直收到相同的错误：

Can't get a response from http://localhost:8761/eurekaapps/ZUULSERVER
Can't contact any eureka nodes - possibly a security group issue?

java.lang.RuntimeException: Bad status: 404

        at java.lang.Thread.run(Thread.java:745)

下面是我的zuul应用程序的application.yml：

info:
  component: Zuul Server

eureka:
  server:
    enabled: true
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka
    registerWithEureka: true
    fetchRegistry: false  

endpoints:
  restart:
    enabled: true
  shutdown:
    enabled: true
  health:
    sensitive: false

zuul:
  route:
    discovery:
      url: http://localhost:9000/polaris/discovery 
      path: /polaris/discovery/**
    sla:
      url: http://localhost:9000/polaris/sla
      path: /polaris/sla/**
    stores: /stores/**
    customers: /customers/**

#remove when spring-boot 1.2.1 is out
security:
  basic:
    enabled: false
management:
  security:
    enabled:
      false

server:
  port: 8765

logging:
  level:
    ROOT: INFO
    org.springframework.web: DEBUG

是不是我弄乱了其中一个值，导致zuul无法看到eureka服务器？它似乎没有正确注册。也许我遗漏了application.yml文件中的一个关键参数？

Answer 1

错误中的线索是"eurekaapps“。您需要在服务URL中添加尾随的"/“：

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

(我认为这是默认设置)。
