Spring / Spring7 basics Interview questions
Describe the RestClient in Spring Framework 7?
RestClient is Spring's modern, fluent HTTP client for synchronous calls, offering a chainable API that's more concise than the older RestTemplate while staying blocking and easy to reason about (unlike the reactive WebClient).
RestClient client = RestClient.create("https://api.example.com"); Product product = client.get() .uri("/products/{id}", 42) .retrieve() .body(Product.class);
As of Spring Framework 7.1, RestTemplate is formally deprecated in favor of RestClient, with actual removal planned for a future Spring 8 release. RestClient also understands the framework's API versioning attribute, so a request can target a specific server-side API version through the same declarative mechanism used on controllers.
