Spring Cloud Data Flow team is pleased to announce the GA release of 2.4.2.

In this release, along with some bug fixes, we primarily focused on the server/client-side performance improvements on the stream management.

The REST layer in Spring Cloud Data Flow server is refactored to accommodate better pagination and performance when retrieving the runtime application statuses of streams. In addition to that, the SCDF dashboard pages are re-worked based on these changes. The Runtime Applications page in the Dashboard has a new layout where the runtime applications are grouped by their streams. The Streams page is also refactored to efficiently retrieve the stream status, application…

I’m pleased to announce the third milestone for Spring Integration 5.3.

This release ships several bug fixes, a bunch of new features and improvements and will be picked up by Spring Boot 2.3 M3 in the near future.

It can be downloaded from our milestone repository:

compile "org.springframework.integration:spring-integration-core:5.3.0.M3"

The most important new features are:

• Reactive transactions support. The ReactiveTransactionManager can now be configured for endpoints which produces reactive type for replies or just implement ReactiveMessageHandler.

• ReactiveRequestHandlerAdvice - a MethodInterceptor for message handlers producing a Mono as a payload for reply. The BiFunction<Message<?>, Mono<?>, Publisher<?>> customized is applied for the returned Mono via Mono.transform(Function) operator to add some aspects into a produced result. Typically it is used for timeout, retry, tag options applied for the remote reactive requests, e.g. Webflux or RSocket.

• Kotlin DSL. As we promised before, we have merged spring-integration-kotlin-dsl project into core one for general availability and for further possible improvements which are possible only with direct access to core Spring Integration classes. See org.springframework.integration.dsl.IntegrationFlowDsl.kt for more information.

Hi, Spring fans! Welcome to another rip-roaring installment of This Week in Spring! My family and I are basically self-quarantined for the meanwhile, trying to avoid the terrifying COVID-19 pandemic that's ravaging communities around the world. This pandemic is bad because it's leaving countless thousands of sick or dead. It also means that it's harder for me to get on planes to meet people.

I'm disappointed I won't be able to - and haven't been able to - make these shows. But, there's always something to be learned and this week is no different. It was a busy week in Spring indeed! Let's get…

Time: approximately 15 mins.

In the previous article, you saw how Spring Boot simplifies the task of writing RSocket servers. But what about RSocket clients? In this article, you’ll learn how to write your own RSocket client and then use this new client to send request-response messages to your RSocket-server. Let’s get started!

This tutorial uses the Linux shell. For details on how to run a Linux shell on Windows, see this Microsoft tutorial.

Step 1: Create A New Spring Boot Project For Your Client

It’s fun to write your own code, so for your RSocket client let’s start from scratch.

If this is too much hassle for you, or you don’t have the time right now, then you can find the code in the rsocket-client folder of the demo code repository.
