In this lesson we use Spring Profiles to enable an application to determine which of our two clients (server-sent events via WebClient, or RSocket) to use to connect to our Kotlin Spring Boot price service. This is the final part of our tutorial showing how to build a Reactive application using Spring Boot, Kotlin, Java and JavaFX.  The original inspiration was a 70 minute live demo. This blog post contains a video showing the process step-by-step and a textual walk-through (adapted from the transcript of the video) for those who prefer a written format. (more…)

In this lesson we add an RSocket client that can talk to the RSocket server we created in the last lesson. This is the ninth part of our tutorial showing how to build a Reactive application using Spring Boot, Kotlin, Java and JavaFX.  The original inspiration was a 70 minute live demo. This blog post contains a video showing the process step-by-step and a textual walk-through (adapted from the transcript of the video) for those who prefer a written format. (more…)

In this lesson we look at connecting our JavaFX chart to our Kotlin Spring Boot service to display real time prices. This is the sixth part of our tutorial showing how to build a Reactive application using Spring Boot, Kotlin, Java and JavaFX.  The original inspiration was a 70 minute live demo. This blog post contains a video showing the process step-by-step and a textual walk-through (adapted from the transcript of the video) for those who prefer a written format. (more…)

This second step shows how to create a Java client that will connect to an endpoint that emits a stream of server-sent events.  We'll be using a TDD-inspired process to create the client and test it. This is the second part in our tutorial showing how to build a Reactive application using Spring Boot, Kotlin, Java and JavaFX.  The original inspiration was a 70 minute live demo, which I have split into a series of shorter videos with an accompanying blog post, explaining each of the steps more slowly and in more detail. This blog post contains a video showing the process step-by-step and

This is the first step in a new tutorial showing how to create a Reactive Spring Boot application: Creating a Reactive service with Kotlin. This month (October 2019) I presented a live demo at SpringOne Platform, showing how to build a Spring Boot application that displays real-time prices, using Spring (obviously), Kotlin and JavaFX. The live demo was recorded and is available as a 70 minute video, but I thought it might be easier to digest as a series of shorter videos with an accompanying blog post, explaining each of the steps more slowly and in more detail, and that's what this tutoria

We’re happy to invite you to our webinar, Reactive Spring, with Josh Long. Join us Thursday, October 5th, 6:00 PM - 7:00 PM CEST (12:00 PM - 1:00 PM EDT). This webinar will give an introduction to Spring 5 and focus on one of its most exciting additions – support for reactive programming, building on the Pivotal Reactor project to support message-driven, elastic, resilient and responsive services. Spring 5 integrates an MVC-like component model adapted to support reactive processing and a new type of web endpoint, functional reactive endpoints. In this talk, we'll look at the net-new Netty-bas
