OpenFeign: Declarative REST Clients
Calling another service shouldn't need the same boilerplate every single time. This module is how OpenFeign turns a service-to-service call into one annotated Java interface.
Learning objectives
- Beginner: Declare a Feign client interface and call another service through it like a local method.
- Intermediate: Configure a Feign client's timeout and add a request/response logging interceptor.
- Advanced: Combine a Feign client with Resilience4j so a downstream call degrades gracefully instead of hanging.
