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 update our live-updating chart to show prices for more than one stock, which means subscribing more than one consumer to our reactive stream of prices. This is the seventh 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 how to use Spring beans from one module in a different module, using auto-configuration. This is the fifth 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

Spring Framework 5 brings full reactive support to developers everywhere. What better way to demo reactive programming than to actually build something live? In this presentation, Trisha creates an end-to-end application using Spring Framework 5, Spring Boot, Reactor, Kotlin and JavaFX, all built using IntelliJ IDEA Ultimate. During this session, we see how these different components work together really easily using Spring. (more…)

In this latest post about Kotlin support in Spring plugins in IntelliJ IDEA, we’d like to point out that Spring Boot is also fully supported for Kotlin. When you run a Kotlin main function that starts a Spring Boot application, it will be automatically recognized as a Spring Boot Run configuration: (more…)
