March 7, 2025 - Avoid RestTemplate unless working on a legacy project, as it is deprecated. For new projects, it is best to use RestClient for synchronous calls and WebClient for reactive needs.

February 7, 2025 - WebClient is for reactive development and RestClient is blocking and was proposed against the use of RestTemplate and many more clients were added to replace template based API like for JdbcTemplate we get JdbcClient

September 30, 2025 - By now, there is a significant gap between RestTemplate and RestClient that we cannot close due to limitations of template-style API. Keeping the RestTemplate around puts part of our community at a disadvantage.

March 28, 2025 - RestClient offers an intuitive API and supports both blocking and non-blocking calls. WebClient is the go-to for reactive applications. RestTemplate should be avoided for new projects.

February 19, 2024 - As seen in these examples, RestClient offers a more streamlined approach to making HTTP requests compared to RestTemplate.

Mono<Thing> fetchThingWithWebClient(String thingId) { return webClient.get() .uri(uriBuilder -> uriBuilder .path("/thing/{id}") .build(thingId)) .retrieve() .bodyToMono(Thing.class); } Thing fetchThingWithRestTemplate(String thingId) { // getForObject() is a handy shorthand method for very simple HTTP calls // exchange().is more widely used for it's better flexibility return restTemplate.getForObject( UriComponentsBuilder.fromUri(URI.create(restTemplateBase)) .path("/thing/{id}") .build(thingId) .toString(), Thing.class ); } record Thing(String id, String name) { } } If you're writing something quick & dirty and not handling error response codes, but wanting to do simple things like: Deal with a list of objects rather than a single object · Add a query parameter to your call. then you'll find RestClient & WebClient easy to modify, but RestTemplate requires a change in method.

October 26, 2023 - In addition, RestClient relies on blocking, synchronous traffic in stead of reactive, asynchronous traffic like WebClient. The benefit of that is that synchronous flows are usually easier to understand, but the drawback is that you may encounter performance issues. There are a few mentions on the internet that RestTemplate is deprecated and that it shouldn’t be used.

May 11, 2024 - While RestTemplate uses the caller thread for each event (HTTP call), WebClient will create something like a “task” for each event.

July 13, 2023 - RestClient can also convert JSON to objects, using Jackson under the hood. In fact, it can convert all types that RestTemplate supports, as it uses the same message converters.

October 25, 2024 - Modern Synchronous Approach: RestClient can serve as a modern synchronous alternative to RestTemplate, particularly when enhanced error handling is needed without the complexity of asynchronous programming.

August 15, 2024 - WebClient is the recommended choice ... with the reactive ecosystem. RestClient provides a middle ground between the two, offering some asynchronous capabilities while maintaining a more familiar API....

August 22, 2024 - Overview: RestTemplate is a synchronous HTTP client that has been the standard in Spring for a long time.

August 23, 2024 - RestClient offers the simplicity and synchronous nature of RestTemplate, combined with a fluent API and advanced configuration options, making it a compelling choice for those who prefer or require blocking operations.

May 26, 2026 - RestClient is a synchronous HTTP client introduced in Spring Framework 6.1 that supersedes RestTemplate.
