Create migration guide from RestTemplate to WebClient

The RestTemplate will be deprecated in a future version and will not have major new features added going forward. https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/client/RestTemplate.html

Could you add a detailed migration guide on how to refactor existing RestTemplate (which typically is for sync blocking requests) into WebClient requests (also sync and blocking)?

Because the usual case for WebClient is probably for async requests, but chances are high that if someone refactors to WebClient he want’s to stick to his synchronous patterns.

Wouldn’t this be a good idea to grab spring users by their hands just now, if it’s planned to deprecate RestTemplate in future anyhow?

Has there been any progress on this, I could not find a guide at: https://github.com/spring-guides

Team Decision: This is a good idea, it needs to be done. It won’t be part of the Spring Framework reference – to avoid bloating it and also because such a guide would go beyond this projects (e.g. some parts would relate to Boot). It should rather be an independent guide, perhaps under https://github.com/spring-guides, but it makes sense to leave the ticket here for now.
