Reactive Spring

Softwareentwicklung mit Open Source

9:10 – 17:15 Uhr
HSR Hochschule für Technik Rapperswil
Max. Teilnehmer: 30


In this Workshop, we will use Spring Framework 5.x and Project Reactor to write Reactive code and will introduce RSocket, an application protocol to supports Reactive Streams.

You’ll get hands-on experience with building a Reactive application to stream data leveraging the newly available Reactive data types, Spring WebFlux, Spring Data and Rsocket. Besides that, we will work with some new tools which make dealing with errors and blocking APIs visible.

This is an updated version of the workshop of last year.


  1. Introduction Reactive Streams, Publisher/Subscriber types and Reactor types
  2. Getting familiar with Project Reactor
  3. Using Spring WebFlux
  4. Functional configuration API for Spring WebFlux
  5. Using Spring Data MongoDB to reactively stream data
  6. Using Reactive Types with Thymeleaf
  7. Using Spring Security Reactive
  8. Using RSocket as a streaming message protocol
  9. Using Reactive RabbitMQ with Spring
  10. Using Reactive Redis with Spring


Participants will build and test the individual parts of a Spring Boot microservices infrastructure themselves. We will use different tools and demonstrate the interaction between them. At the end of the day, participants will take along a backpack of tools, working techniques, and terms that will help them successfully implement reactive components with Spring Boot.


This workshop is targeted at developers and architects who are new to reactive programming and want to learn how to use the Spring ecosystem to get started.


Java and Spring Boot knowledge


In order to participate, you will need:

  • A laptop with at enough spare disk space and RAM
  • Java, Maven and your favorite IDE installed (Eclipse, Spring STS, IntelliJ, Netbeans)
