微服务Spring Cloud zuul报错：com.netflix.zuul.exception.ZuulException:

这就是错误信息，很奇怪；困扰我有半个小时才解决；
我这里用的是application.properties的配置文件；

• o.s.c.n.z.filters.post.SendErrorFilter : Error during filtering （译文：误差在过滤）

com.netflix.zuul.exception.ZuulException:

• 之前的配置信息：首先排除了代码有错，因为这是我在之前的微服务上添加的网关
  错误就在zuul网关超时，每次请求必定要报这个错误。

# 网关名字
spring.application.name=eureka-client-zuul
server.port=9091
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka

# 城市列表提供者
zuul.routes.city.path=/zuulCity/**
zuul.routes.city.serviceId=cityDataProvider-eureka

# 自身api提供者
zuul.routes.myapi.path=/myapi/**
zuul.routes.myapi.serviceId=projectProvider-eureka

• 在配置文件里面添加zuul网关超时配置就可以了；
  在这里感谢这位大佬的博客给我的启发 https://blog.csdn.net/tianyaleixiaowu/article/details/78772269

# 在这里路由方式是 url方式的，Zuul的超时配置
zuul.host.connect-timeout-millis=2000
zuul.host.socket-timeout-millis=10000
