我有一个简单的Zuul代理服务器用作网关的两个服务。服务总是令人放心。如果我直接访问他们，没有问题。但是当我通过祖鲁访问它们时，它可能会或可能不会工作。在某些情况下，我在调用服务时收到HTTP 500响应。它真的让我发疯。有时，服务均达到，有时没有，半秒后，它适用于下一个视图分钟，然后再......闪烁Zuul TimeoutExceptions使用@EnableZuulProxy与春季启动和尤里卡

错误如下：

我的配置看起来像这样（我optionaly配置在YAML的路线，但问题是相同的）

server: 
    port: ${PORT:9098} 
logging: 
    level: 
    ROOT: INFO 
    org.springframework.web: DEBUG

    statusPageUrlPath: /info

    prefer-ip-address: true

    serviceUrl:

zuul: 
    # If not set, Authorisation headers will not pass 
    sensitive-headers: Cookie,Set-Cookie 
    # Or get by eureka 
    routes: 
    auth-service: 
     url: http://localhost:8080 
    rest-service: 
     url: http://localhost:8081

主要类

@EnableEurekaClient 
@EnableZuulProxy 
@SpringBootApplication 
public class ZuulGatewayApplication { 

    public static void main(String[] args) { 
     SpringApplication.run(ZuulGatewayApplication.class, args); 
    }

有什么不对？我错过了什么吗？感谢任何提示。

解决方案（更新）：变与工作配置

这是否是在Zuul启动后第一次发生？您是否尝试过配置Hystrix和Ribbon超时值？ –

它看起来像内部Zuul豪猪超时。 默认值只有1000毫秒。 尝试像下面那样增加超时值。

hystrix: 
    command: 
    default: 
     execution: 
     isolation: 
      thread: 
      timeoutInMilliseconds: 3000

注意：即使您正在使用旗语隔离是默认zuul，你应该使用上述财产究竟包括thread。

谢谢，这是我需要的提示。它现在也可以通过从尤里卡获得路线。 –

Zuul没有Eureka：

application.yml：

在此文件中不需要与尤里卡相关的配置。

... 
ribbon.eureka.enabled: false 
zuul: 
    ignoredServices: "*" 
    routes: 
    zuulDemo1: 
     path: /zuul1/** 
     url: http://localhost:8600/ 
# stripPrefix set to true if context path is set to/
     stripPrefix: true 
...

Zuul与Eureka：

application.yml：

除了尤里卡相关配置：

... 
#ribbon.eureka.enabled is true by default. 
#ribbon.eureka.enabled: true 
zuul: 
    ignoredServices: "*" 
    routes: 
    zuulDemo1: 
     path: /zuul1/** 
# serviceId as registed with Eureka. Enabled and used when ribbon.eureka.enabled is true. 
     serviceId: demo-zuul-api1 
# stripPrefix set to true if context path is set to/
     stripPrefix: true 
...

这适用于ribbon.eureka.enabled：false。但是在使用eureka时，我得到了与问题中所述相同的错误。 –

@NicolasSchwarzentrub 您能否在使用Eureka发现服务时描述您的Zuul配置？如果您的Zuul配置如下所示： ... 路线： 身份验证服务： 网址：HTTP：//本地主机：8080 REST的服务： 网址：HTTP：//本地主机：8081 ... 服务都没有发现，但硬编码。没有关于使用Eureka – ootero

就像在我更新后的帖子。它现在也适用于尤里卡 - 其他答案也有所帮助。 –
