Excellent, thanks.. I hope you will continue to upload often ☺️

Thank you! That's the plan 🙂

That's so nice! The declarative option using interface is very useful.

@oddybassey8474 11 месяцев назад

loved how you gave really good and concise examples and explanation. Thanks for making the video!

Thank you for such a nice feedback! I'm super happy you found it useful!

Thanks, it is nice material. Good overall overview without annoying details.

@MrSurprise777 7 месяцев назад

Briefly and understandable, thanks! Important note that by default RestClient uses Java HttpClient introduced in Java 11

Nice, using the interfaces will make things much cleaner.

@SpringAcademy 11 месяцев назад

Indeed!

@user-jb8we4ly1s 9 месяцев назад

But how can we manage errors? For example: external api returns 404. How can I handle that api response body to return that exact same message using my own ApiErrorDTO?

Thanks for the video. I would like to understand how to enable micrometer tracing with RestClient? using RestClient.Builder when creating the bean and using that is not propagating the traceparent header to other api service.

Awesome new component! I was messing around with it but i didn't get working the RestClient with OAuth2 client_credentials, it could be that spring security support is currently a WIP? Excelent channel BTW!!

@SpringAcademy 11 месяцев назад

Likely. It's still few months before the RC so I'm pretty sure they'll fill the gaps

@nbugash 11 месяцев назад

Well done. Quick question can you use still flux / mono in the interface? E.g `public Flux …..`

@SpringAcademy 11 месяцев назад

Not sure if RestClient handles it but anyway I don't think it would bring any value. For reactive interfaces you can still use WebClient under the hood

@chardou85 9 месяцев назад

It's look like Spring Cloud OpenFeign. Is there any difference between this two ? The usage of RestClient over Feign is now recommended by Spring ?

@rustemtaralov3884 11 месяцев назад

what about FeignClient is it stil good

Does anybody know which Spring Boot version will use the Spring Framework 6.1?

@SpringAcademy 11 месяцев назад

Spring Boot 3.2. Check calendar.spring.io/ for release dates

Hi, Will learning Spring Webflux boost my resume ? Please give me your opinion.

@SpringAcademy 11 месяцев назад

It definitely will but considering how niche the reactive programming is I would recommend learning something more mainstream to boost your resume

@Eagle3302PL 11 месяцев назад

As long as you don't become one of those devs that uses reactive for everything, recently had to refactor a whole new service because an overeager dev used reactive for a simple rest microservice and FE guys said they wanted pagination after I took over. It's important to learn when to use reactive programming, it's an overkill tool for simple services.

@anthonya880 11 месяцев назад

Thank you guys for replying.

@Chrisbees 7 месяцев назад

@@SpringAcademywhat are the mainstream alternatives to webflux? I just learnt vertx and use it instead of webflux. So I’m wondering if I really need to learn webflux

@Razpirato 11 месяцев назад

Does this also work with virtual threads?

@SpringAcademy 11 месяцев назад

It depends if the underlying low level HTTP client works with virtual threads. I'm sure that all major ones eventually will or they already do considering how virtual threads are easy to use in existing application.

@Razpirato 11 месяцев назад

Out of curiousity, why didn't you want add Webflux and WebClient as a dependency?

@SpringAcademy 11 месяцев назад

If dependency brings no to little value I just prefer to avoid it. Especially considering how spring boot autoconfiguration behavior changes depending on what's on the class path
