Declarative Clients in Spring

on YouTube ↗48m

" summary

Compares existing Spring Cloud OpenFeign integration with a new Spring approach that implements interface HTTP clients via a proxy factory, shows a working demo of a customer → verification POST flow using Spring Cloud OpenFeign, a Retrofit/WebClient incubator (v0.4.1) and a new http exchange annotation that maps to concrete methods, and wires into WebClient adapter for non‑blocking calls, load balancing and tracing; prototypes run successfully and raise AOT/native and code‑generation tradeoffs.
