ZuulException：Zuul-Eureka的前向错误

Question

在与Zuul和Eureka一起路由时我正面对着ZuulException: forward error。

在第一分钟内没有发生错误，但是在1或2分钟之后我得到了这个奇怪的错误。

我正在使用spring boot 1.4和spring cloud Camden

如果您想重现错误或看到我的项目：https://github.com/Seb69/Spring-demo-ZuulException/tree/master

尤里卡配置：

server:
    port: 9999

spring:
    application:
        name: eureka-server
eureka:
   instance:
     hostname: localhost
   client:
     registerWithEureka: false
     fetchRegistry: false
     serviceUrl:
       defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

服务网关配置（Zuul）：

server:
    port: 1111
spring:
    application:
        name: service-gateway

# ZUUL (Load balancing)
zuul:
    ignoredServices: '*'
    routes:
        service-server:
            stripPrefix: true
            path: /api/**
            serviceId:  SERVICE-SERVER


# EUREKA (Service registry)
eureka:
    instance:
        leaseRenewalIntervalInSeconds: 1
        leaseExpirationDurationInSeconds: 2
    client:
        serviceUrl:
            defaultZone: http://localhost:9999/eureka/

服务配置：

server:
    port: 8095
spring:
    application:
        name: service-server

eureka:
    instance:
        leaseRenewalIntervalInSeconds: 1
        leaseExpirationDurationInSeconds: 2
    client:
        serviceUrl:
            defaultZone: http://localhost:9999/eureka/

这是我的堆栈跟踪的简短版本：

com.netflix.zuul.exception.ZuulException：转发错误

引起：com.netflix.client.ClientException：下次服务器上的重试次数超过最多1次重试，同时调用：mbp-de-andre：8095

引起：java.net.UnknownHostException：mbp-de-andre

Answer 1

FIX：所以，我终于成功了！

我的问题来自我的Macbook主机名，

最后的主机名是：mbp-de-andre

我修改它并设置：`MacBook-Pro-de-ANDRE.local``

Answer 2

只是想说另一个修复可能缺少依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
</dependency>
