我在我的微服务设置中使用 spring 云网关作为 API 网关，并使用 consul 作为服务发现。

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：

java.io.IOException: Connection closed prematurely

我多次尝试相同的 API，2 分钟后我得到了这个错误。

有没有属性设置。版本和依赖项详细信息：

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

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，默认超时为 2 分钟。

参考：https ://github.com/expressjs/express/issues/3330

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。

我通过更改节点应用程序中的超时值来解决它

I also encountered a similar problem. When spring gateway called other services, it reported the same error when uploading files. I try to add the following configuration to the yaml file of the called service. That's the solution. You can try it, too

spring: servlet: multipart: max-file-size: 50MB max-request-size: 50MB
