openfeign / feign-cdi Goto Github PK

Feign is an amazing library for working with type safe REST clients. It simplifies a lot of day to day development work being able to leverage the client.

CDI is a dependency injection tool. While a user can define producer methods there is still the boilerplate overhead that they may have to deal with.

I'd like to propose adding a CDI module, which will look for interfaces supporting Feign and provide injection points to CDI users to simply inject their clients. No additional development, all annotation based and configured as needed.

It should provide some kind of fallback to look for common builders for interfaces and leverage those whenever possible.

Copied from original issue: OpenFeign/feign#500

There are an error in the Feign CDI module, when the producer bean tries to get the bean client scope annotation.

Calling getClass() on an annotation may return a proxy class instead of wanted class.

Add support for the optional capabilities provided in Hystrix module. Since the module provides its own builder, need to leverage that builder instead of the native builder.

Instead of expecting all config in annotations, we should also support produced instances.

Provide some core Feign integration - able to create injection targets based on properly annotated feign interfaces.
