How to add Feign Client to my AutoConfiguration Spring Starter

Question

I have my couple micro-services "A" and "B". Service "A" should talk with service "B" via REST. In a simple way I create Feign client in service "A" and use it like a proxy to request API of service "B".

But I want to create my own service "B" spring starter with Feign client inside this starter. I want it order to add starter in dependency service "A" and just using ready client service "B".

I have never create my own spring starter and have read couple tutorials and did some success examples. But I stuck when I try to add my Feign client into the AutoConfigure class of my starter.

How to proper add Feign Client Spring Bean to my AutoConfigure class?
