@philwebb Can you explain bit more on this, so I can submit PR?

@anandshah123 Thanks for the offer, but unfortunately behind the innocuous title there is quite a bit of work here. Spring Framework 5 is working on a reactive web stack and this issue is a placeholder for all the work required to get that effort into Spring Boot. It's likely that the effort will take quite some time and involve quite a lot of changes as the Spring Framework 5 effort continues.

If it's an area that interests you we'd very much appreciate feedback when the work starts in earnest. You can already see the core framework changes progressing here: https://github.com/spring-projects/spring-reactive.

The spring-reactive repo has now been merged into Spring Framework and is available as the 5.0.0.BUILD-SNAPSHOT version. We're working on Spring Boot 1.4 and 1.5 - this feature is in the Boot 2.0 milestone.

In the meantime, you can check the experimental Boot Starter project.

Is is possible to have a version working with spring-boot 1.4.x? Or more in general is it possible to have a version that works right now? I tried current version and it does not work. I followed instructions here: https://spring.io/blog/2016/07/20/notes-on-reactive-programming-part-iii-a-simple-http-server-application

@pabloa Could you take a look at the dedicated Boot Starter? The README explains everything you need to get started.

This starter currently works with Boot 1.4, so I don't understand what you mean. Please open an issue there if you've found a problem. Don't forget to add all the necessary details or a repro project.

Initial support has been merged in master, the Spring Boot experimental starter is now closed.
