使用带弹簧启动和eureka的@EnableZuulProxy闪烁Zuul TimeoutExceptions

问题描述 投票：1回答：2

我有一个简单的Zuul代理用作两个服务的网关。这些服务总是可以使用的。如果我直接访问它们，没问题。但是当我通过Zuul访问它们时，它可能会也可能不会起作用。在某些情况下，我在调用服务时会收到HTTP 500响应。真的让我很生气。有时服务到达，有时不到，半秒后它可以用于下一个视图分钟然后再次...

错误如下：

我的配置看起来像这样（我选择配置yaml中的路由，但问题是一样的）

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

eureka:
  instance:
    leaseRenewalIntervalInSeconds: 5
    statusPageUrlPath: /info
    healthCheckUrlPath: /health
    metadata-map:
      instanceId: ${spring.application.name}:${random.value}
    prefer-ip-address: true
  client:
    serviceUrl:
      defaultZone: ${vcap.services.eureka-service.credentials.uri:http://localhost:8761}/eureka/
management:
 security:
   enabled: false



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

主要课程

@EnableEurekaClient
@EnableZuulProxy
@SpringBootApplication
public class ZuulGatewayApplication {

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

怎么了？我错过了什么吗？谢谢你的任何提示。

在Zuul里面看起来像Hystrix超时。默认值只有1000毫秒。尝试增加超时值，如下所示。

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

注意：即使您使用的是zuul默认的信号量隔离，也应该使用上面的属性，包括thread。

没有Zuul的Eureka：

application.yml：

此文件中不需要与Eureka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Eureka相关配置外：

...
#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
