QUESTION
I know that Spring Cloud at some version (3.0?) dropped direct support for some Netflix libraries like Ribbon or Hystrix. Now I'm trying to make a smooth migration of around 20 microservices running on production having some custom code extending Ribbon (and Hystrix to a lesser degree). The main goal is to upgrade from Spring Boot 2.3 to 2.6. As a consequence I need to upgrade Spring Cloud to 3.1.x, right?
My guess was to proceed with 2-step upgrade to avoid a one big-step migration:
- Upgrade to Spring Boot 2.6 and Spring Cloud 3.1 while still using Ribbon and Hystrix
- Make a way through a jungle of an old code and getting rid of Ribbon and Hystrix in smaller increments.
However to achieve this I'm trying to use simultanously Spring Boot 2.6, Spring Cloud with release train 2021.01 and 2 selected starters from older Spring Cloud (latest versions of these artifacts):
spring-cloud-starter-netflix-hystrix 2.2.10.RELEASE
spring-cloud-starter-netflix-ribbon 2.2.10.RELEASE
Is this possible at all? We are heavilly using Feign and Spring WebClient - client-side load-balancing must work for these. So far I found out Feign clients are not automatically integrated with Ribbon.
@spencergibb @OlgaMaciaszek - especially counting on you.
...ANSWER
Answered 2022-Apr-12 at 10:13Answering my own question after receiving confirmation from Spring Cloud team by other means: this is a bad idea to try use Ribbon with Spring Cloud 2021.01 and it would require a really hard work to make it working.

Answered 2022-Mar-06 at 15:36There’s a relatively new Gradle feature called “version catalogs”. With those you can centrally declare dependencies that you’d like to share between multiple projects of your build (or even between different builds).
In your concrete example, you’d add something like the following to your settings.gradle

And for this issue I used spring cloud gateway instead of Zuul which is the alternative provided by spring

QUESTION
How do you override the Hystrix default configuration for OpenFeign? Most of the documentation out there is for SpringBoot + OpenFeign, which has its own Spring-specific configuration override system.
Ideally it would be possible to configure the Hystrix core size for the client and configure and timeouts on a per endpoint basis.
...ANSWER
Answered 2021-Sep-15 at 20:40Hystrix OpenFeign has a setterFactory()
method on the builder that allows you to pass in a SetterFactory lambda function that is executed when setting up each target endpoint:
