Project Reactor is Spring’s implementation of Reactive Streams (in version 3 and beyond). It has two main publishers, Flux<T> and Mono<T>. It also uses Schedulers much like RxJava.

The Spring Framework has many integrations with Reactor that make it easier to use with other Spring projects, such as Spring Data and Spring Security.
