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.

Hi, Spring fans! Welcome to another installment of Spring Tips. In this episode we're going to look at the new Kotlin DSL for Spring Security. I love Kotlin. I introduced Kotlin in several other Spring Tips videos: The Kotlin Programming Language, Bootiful Kotlin Redux, and Spring's Support for Coroutines. Some of those videos are very old! There are already a number of different projects in the Spring diaspora that are shipping Kotlin DSLs. They include, among others, Spring Framework, Spring Webflux, Spring Data, Spring Cloud Contract and Spring Cloud Gateway. And now, Spring Security!

Spring Security is an amazing project - it solves some of the hardest problems in the industry and helps people secure their applications. And, as if that weren't enough, it's displayed a steadfast determination to make security easy. If you ever used Spring Security in its earliest incarnations, you'd know that it required loads of XML - pages! - to get anything done. That improved to the point where in Spring Security 3 you…
