How to set custom Feign client connection timeout?
提问by Roman Cherepanov
I have Spring Boot application with this Gradle dependencies:
我有具有此 Gradle 依赖项的 Spring Boot 应用程序：
compile("org.springframework.cloud:spring-cloud-starter-eureka")
compile("org.springframework.cloud:spring-cloud-starter-feign")
compile("org.springframework.cloud:spring-cloud-starter-ribbon")
compile("org.springframework.cloud:spring-cloud-starter-hystrix")
compile("org.springframework.cloud:spring-cloud-starter-config")
Also I have Feign client:
我还有 Feign 客户端：
@FeignClient(name = "client")
public interface FeignService {
@RequestMapping(value = "/path", method = GET)
String response();
}
My application.properties:
我的application.properties：
client.ribbon.listOfServers = http://localhost:8081
ribbon.eureka.enabled=false
When query time is more than 1 second I get exception:
当查询时间超过 1 秒时，出现异常：
com.netflix.hystrix.exception.HystrixRuntimeException: response timed-out and no fallback available.
So my question is:how can I set custom Feign client connection timeout? For example to 2 seconds.
所以我的问题是：如何设置自定义 Feign 客户端连接超时？例如到 2 秒。

I solved my problem using this answeron question: Hystrix command fails with “timed-out and no fallback available”.
我使用以下问题的答案解决了我的问题：Hystrix command failed with “timed-out and no fallback available”。
I added hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=4000to my application.propertiesto set custom timeout.
我添加hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=4000到我application.properties的设置自定义超时。

You can be configured timeout using configuration properties on application.yaml file:
您可以使用 application.yaml 文件上的配置属性配置超时：
feign:
client:
config:
default:
connectTimeout: 5000
readTimeout: 5000
Notice that this will change your default feign configuration, if you want to update the timeouts just for your client replace defaultwith the name configured in @FeignClientin your case it will be client, another thing is that you must specify both connectTimeoutand readTimeoutfor this to take effect.
请注意，这将更改您的默认 feign 配置，如果您只想为您的客户端更新超时，请替换default为@FeignClient在您的情况下配置的名称client，另一件事是您必须同时指定两者connectTimeout并readTimeout使其生效。
