Spring 7 removes Feign as the default for declarative HTTP calls, introducing @HttpExchange and @ImportHttpServices so developers can use spring‑web’s @GetExchange with RestClient or WebClient, while keeping configuration and security aligned with Spring Boot 4 and Security 7.
The article analyzes Spring Framework’s new native HTTP Interface (@HttpExchange), comparing it with OpenFeign in terms of architecture, dependency management, performance, and suitability for reactive programming, and provides migration guidance and practical code examples.
This article reviews traditional Spring MVC controller definitions, introduces the new @HttpExchange annotation introduced in Spring 6 for declaring HTTP interfaces, demonstrates its usage with code examples, and shows how to generate client proxies for type‑safe HTTP calls.
This tutorial walks through Spring Boot 3’s built‑in @HttpExchange annotation, showing how to replace OpenFeign with a lightweight, declarative HTTP client using WebClient, complete with server and client code, configuration steps, and a runnable test example.
This tutorial explains Spring 6 and Spring Boot 3's built‑in support for declarative HTTP clients, showing how to define annotated Java interfaces, configure Maven dependencies, inject WebClient, and write unit tests with code examples.
