The new generation of Spring Boot applications is here! With Spring Boot 2, developers can use the new Spring WebFlux reactive web framework to build fully async event-loop based web applications. But some of these features are also available for your regular Spring MVC application. During this live coding session, Stéphane will upgrade an existing Spring Boot 1.5 web application to Spring Boot 2 and showcase features such as the new WebClient API, Actuator, Developer Tools, and more.
