即使微服务已在Eureka Service Discovery中注册，Netflix ZuulProxy也会返回HTTP错误500

Question

我有一个微服务，它在eureka中注册了什么，我可以在服务发现中看到。 我也有一个带有正确的eureka服务器服务URL的Zuul服务器。

Zuul application.properties文件：

spring.application.name=zuul-server
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=true
eureka.client.serviceUrl.defaultZone=${EUREKA_URI:https://"eureka-server"/eureka}
management.endpoints.web.exposure.include=routes
zuul.host.connect-timeout-millis=5000

Zuul application.yml文件：

zuul:
  routes:
    unasapi:
      path: /microservice/**
      serviceId: microservice
ribbon:
  eureka:
    enabled: false
microservice:
  ribbon:
    listOfServers: https://microservice.com/

我的Eureka服务器application.properties文件：

server.port:8760

eureka.client.register-with-eureka=true
eureka.client.fetch-registry=true

logging.level.com.netflix.eureka=OFF
logging.level.com.netflix.discovery=OFF

eureka.server.enable-self-preservation=false
eureka.server.renewal-percent-threshold=0.85

我的Eureka服务器application.yml文件：

hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 15000
ribbon:
    ReadTimeout: 15000

我的微服务application.properties文件：

server.port=62114

还有我的Microservice application.yml文件：

spring:
  application:
    name: microservice
eureka:
  client:
    serviceUrl:
      defaultZone: https://eureka.com/eureka

stacktrace我所拥有的：

}

当我调试时，请求将不会到达微服务。

我尝试了很多配置，但到目前为止没有任何效果。 请帮我解决这个问题。

非常感谢！

Answer 1

为什么您要在zuul中禁用功能区，同时也禁止zuul在尤里卡注册？

对于zuul路由到服务，它必须知道服务名称及其服务器列表，zuul从尤里卡（eureka）检索到的此信息，功能区使用它将请求路由到相关服务。

在zuul中同时启用eureka和功能区，它可能应该开始路由。
