Can we use both Web MVC and WebFlux in the same application?

As of now, Spring Boot will only allow either Spring MVC or Spring WebFlux, as Spring Boot tries to auto-configure the context depending on the dependencies that exist in its classpath.

Also, Spring MVC cannot run on Netty. Moreover, MVC is a blocking paradigm and WebFlux is a non-blocking style, therefore we shouldn’t be mixing both together, as they serve different purposes.
