🚀 Spring Framework 7 and Spring Boot 4 are simplifying how we handle service-to-service communication! In this tutorial, I'll show you how the new HTTP Interfaces feature eliminates some of the boilerplate code that's been slowing us down.

We're looking at this feature by building a Todo API that communicates with external services. You'll see exactly how the new approach with HTTP Interfaces makes your code cleaner and more maintainable. I'll walk you through both the traditional approach and the modern Spring Boot 4 way, so you can see the dramatic difference for yourself.

🎯 What You'll Learn:
✅ How to migrate from RestTemplate to RestClient (the future of Spring REST communication)
✅ Creating declarative HTTP interfaces without writing implementation code
✅ The new @ImportHttpServices annotation that eliminates proxy factory boilerplate
✅ Building a complete CRUD API with minimal code using Spring Boot 4
✅ Advanced configuration options for grouping and customizing multiple HTTP services

📋 Key Takeaways:
✅ RestTemplate is officially being deprecated
✅ Spring Boot 4's modularization requires explicit imports
✅ One annotation (@ImportHttpServices) replaces complex bean configuration
✅ Perfect for microservices architecture and API-first development

Spring Framework 7 and Spring Boot 4 simplify service-to-service HTTP communication by reducing boilerplate in HTTP interfaces. Previously, developers had to manually create a RestClient, wrap it in a RestClientAdapter, and use HttpServiceProxyFactory to generate a proxy bean. The new @ImportHttpServices annotation on a @Configuration class eliminates this setup entirely — just declare which interface types to import and Spring auto-wires the proxy beans. The video walks through a full example using the JSONPlaceholder API: starting from a traditional RestClient-based service, moving to HTTP interface stubs, and finally using the new annotation-driven approach in Spring Boot 4 RC1. RestTemplate is now officially deprecated in favor of RestClient.

Creating REST Clients in Spring Boot 4 Just Got EASIER!
