Non-blocking WebClient. RestClient, on the other hand, is non-blocking and asynchronous, which means it does not block the calling thread. It's the testing counterpart of the RestTemplate. As you know, RestTemplate, the only tool in the Web MVC stack to call remote REST APIs, has been retired and is in maintenance mode. Simple use cases with straightforward HTTP operations. ai. Create a new resource RestClient. Let's write a RestClient with the builder method to call the customer API. postForEntity. WebClient is part of the Spring WebFlux library. as stated in the RestTemplate API. Currently, there’s no release yet of Spring Boot that includes RestClient. In RestTemplate this class is returned by getForEntity() and exchange(). Applications that need to handle many concurrent requests efficiently. It offers templates for common scenarios for each HTTP method, in addition to the generalized exchange() and execute() methods that support less frequent cases. Think of RestTemplate as actually creating a new Thread for each event, vs WebClient creating a Task (as if on a queue, which is essentially what Reactor manages for you behind the covers). One of RestTemplate's original authors, Brian Clozel, has stated:. You're right that this change of behavior is due to #31882 and #32003 and I think they're valid.

Spring has officially stated that RestTemplate is in maintenence mode so if you can, use WebClient if you want to be as future proof as possible. Its strength is handling all the IO and handing you a ready-to-go Java object. With RestClient, we're using the JdkClientHttpRequestFactory (so JDK 11 java. It works WebClient. An Abstract controller class requires List of objects from REST. It plays a crucial role in consuming RESTful services, allowing developers to send requests to and RestClient vs. They enable seamless communication between services, making them ideal for both external APIs and internal service-to-service interactions in microservices or monolithic architectures. WebClient is in the reactive WebFlux library and thus it uses the reactive streams approach.
