Spring Cloud Gateway 使连接过早关闭 [英] Spring cloud gateway gives connection closed prematurely
问题描述
我在微服务设置中使用 spring cloud gateway 作为 API 网关,consul 作为服务发现.
I am using spring cloud gateway as API gateway in my micro service setup with consul as service discovery.
在某些情况下,当某些微服务的 API 花费超过 2 分钟时,网关会抛出以下错误:
In some case when API of some microservice take more then 2 minutes, gateway throws below error:
java.io.IOException: Connection closed prematurely

我多次尝试相同的 API,刚好在 2 分钟后出现此错误.
I tried the same API multiple time, I got this error exactly after 2 minutes.
是否有任何属性设置.版本和依赖项详细信息:
Is there any property settings. Version and dependency details:
compile('org.springframework.cloud:spring-cloud-starter-consul-discovery')
compile('org.springframework.cloud:spring-cloud-starter-gateway')
compile('org.springframework.cloud:spring-cloud-starter-openfeign')
springBootVersion=2.0.3.RELEASE
springDMPVersion=1.0.4.RELEASE
springPlatformBomVersion=Cairo-SR2
功能区设置:
ribbon:
ConnectTimeout: 3000
ReadTimeout: 3000
推荐答案
下游服务出现问题.
在我的应用程序中,有 nodejs 应用程序在 spring 云网关后面运行,默认超时时间为 2 分钟.
In my application, there is nodejs application is running behind the spring cloud gateway and default time out is 2 min.
参考:https://github.com/expressjs/express/issues/3330一个>
在我的情况下,2 分钟后,nodejs 应用程序超时,这就是我在网关中收到错误的原因.
In my case after 2 min, nodejs application gives timeout and that is why I get an error in the gateway.
我通过更改节点应用程序中的超时值解决了这个问题
I resolved it by changing timeout values in node application
