Declarative Clients in Spring

What is a declarative HTTP client vs. an imperative one? Why are they useful and why should I care? We’ll talk about options that are available in the Spring portfolio and what’s coming on the horizon. In this session, we’ll look at the history of declarative clients in Spring via Spring Cloud OpenFeign. We’ll also dive into upcoming options that are coming to Spring and the advantages that these new technologies bring to the developer experience.

There are links to resources in the presentation, but where is a link to the presentation?

This is exactly what I was looking for. I used OpenFeign but since I've decided to explore the reactive stack within Spring I found quite lack of support for it and wasn't truly sure about embracing Spring Cloud Square for Production given it's an Incubating project. Very clear and well explained, thanks for talk Olga! And thanks to the whole team for this initiative!

Amazing presentation, I was in research of a client interface to use

Amazing

thanks for this impressive talk. I have a question: I just setup a new customer project in Spring Boot 3 / Spring 6 and migrated the adapting layers to use Spring Cloud OpenFeign client, which worked out quite well so far. Especially I took advantage of OpenApi's "spring cloud" generator to have the client interfaces all be generated. We just inject them (under the hood their proxy) to the service who does the call. If I would switch in this szenario to the Http client using the HttpServiceProxyFactory bean, can I still generate the client interfaces via openApi? Is there already some generator out or will it be out soon?

open feign has some problems with message converters, it doesn't go well with multipart request with mixed content (json + file)

Please share the links to the slides and repo. Thanks.
