Spring has officially deprecated RestTemplate in favor of the new RestClient (and WebClient for reactive/streaming).
To help you (and your legacy code 😉) make the move, I’ve prepared a slide deck that you can browse as a carousel attached to this post.
📚 In the carousel you’ll find:
🔸 BEFORE / AFTER FOR EACH VERB
▪️ GET – from getForObject() to a fluent get().uri().retrieve().body()
▪️ POST – creating resources with a cleaner, discoverable API
▪️ PUT – still idempotent, but now with explicit ResponseEntity control
▪️ DELETE – from “fire-and-forget” to a fluent pattern consistent with other verbs
🔸 WHY THIS MATTERS
▪️ RestTemplate is now officially deprecated
▪️ RestClient offers a modern, fluent API aligned with WebClient
▪️ Easier to teach, easier to read, easier to maintain
👉 Action:
Open the carousel attached to this post to see side-by-side code for RestTemplate vs RestClient on GET / POST / PUT / DELETE.
Perfect for: code reviews, refactoring sessions, or explaining the change to your team/students.
What are you using today in your projects? Still RestTemplate, already on RestClient, or fully WebClient? Tell me in the comments 👇
