In the integration environment we need to frequently change feign client url due to some unavoidable circumstances
Deploying application everytime after change in the feign client url is not a wise idea. Feign comes with out of the box support for loading URL through configuration property feign.client.{contextId}.url. Since this property is applied at the application startup during FeignClient instance creation and there is no way to refresh these settings via /actuator/refresh. However, feign client connectTimeout and readTimeout are refreshable with the enablement of the property feign.client.refresh-enabled.
Possible solution
Whenever feign.client.refresh-enabled=true then FeignClient constructed from org.springframework.cloud .openfeign.FeignClientFactoryBean should be composed with Refresh scoped ReferableHardCodedTarget<T> (new target extending feign.HardCodedTarget<T>). ReferableHardCodedTarget<T> will have refreshcoped URL bean RefreshableUrl instead of url property of type string.
Then /actuator/refresh will be able to refresh feign.client.{contextId}.url via RefreshableUrl bean.
Feature demand After looking at issue #483, I have realised that many of us are expecting this feature to be available. Refer to this comment.
Additional context If the request looks justified then I will be happy to contribute the same.
