Spring WebFlux is a reactive web framework for spring.

Is Spring WebFlux is a replacement for Spring MVC?

No. Go through below points to get some clarity.

a.   Spring MVC is based on Servlet API, where are Spring WebFlux is based on Reactive Streams.

b.   Spring WebFlux uses non-blocking APIs available in servlet 3.1+ specification onwards, where as Spring MVC uses blocking APIs. That means spring MVC uses synchronous programming model, where as WebFlux uses asynchronous programming model.

c.    Since Spring MVC depends on old servlet specification, one dedicated thread is given per request. But in case of WebFlux a pool of worker threads are responsible to execute given task.

Can I use Spring MVC and WebFlux together in same web application?

Yes
