The Spring Framework and the Reactor teams have been busy working on support for reactive programming models for more than 2 years and result of that Spring 5 GA is just around the corner in Q1 2017. This talk discusses what reactive programming is and tries to make sense of the transition from traditional application development to reactive programming. It also explains and demonstrates the reactive web features in Spring Framework 5 including support for annotated controllers (on a reactive foundation) as well as a new, light-weight functional, programming model.
