Hi, Spring fans! We hope you’ll join us for an interactive, 24-hour long, virtual conference called Spring Live. Here’s what you need to know: it’s 24-hours long, end to end, so there’s bound to be content you can watch no matter what part of the world you’re in. It’s free! It’s interactive - so the speakers will be hanging around to answer questions and do Q/A. Some speakers are going to pre-record their talks proper just so they can spend the entire slot for their talk answering questions and interacting directly with you. We’ve invited experts from the wide world of Springdom from VMWare (where the Spring team lives), Okta, Confluent, Google, Microsoft, and IBM, and so many others.

Spring Tips: Remote File System Integrations (FTP) with Spring Integration

Spring Tips: FTP Integration

speaker: Josh Long (@starbuxman)

Hi, Spring fans! In this installment of Spring Tips, we look at a topic that’s near and dear to my heart: integration! And yes, you may recall that the very first installment of Spring Tips looked at Spring Integration. If you haven’t already watched that one, you should. So, while we’re not going to revisit Spring Integration fundamentals, we’re going to take a deep dive into one area fo support in Spring Integration: FTP. FTP is all about file synchronization. Broadly, in the world of Enterprise Application Integration (EAI), we have four types of integration: file synchronization, RPC, database synchronization, and messaging.

This Week in Spring - March 17th, 2020

Hi, Spring fans! Welcome to yet another installment of This Week in Spring! We’re already midway through March 2020, and I can’t believe how crazy things have gotten! You’re no doubt experiencing something equally as odd too. The pandemic has truly changed this world in a way nothing else has in recent memory. It’s crazy to think about the course this virus has taken and the journey we’ve all taken along with it.

I live in San Francisco, and we’re currently under lockdown. It’s technically a crime now to leave your home for anything but essential needs like food, medicine, or walking the dog. That’s OK. That just leaves more time for us to learn and socialize, albeit online and from the confines of our own homes. We’re very lucky, you know? How wild. Most of us who work on software should be able to work from home. There are some glaring exceptions, of course, as detailed in this epic megathread, but basically, software can be done online. It requires some of us to revise our workflows, but it can be done.

Getting Started With RSocket: Spring Boot Fire-And-Forget

Time: about 15 minutes.

Some developers reading this post will have been using HTTP for many years by now. Most of them will also know that if you want to use HTTP with other messaging models — like fire-and-forget, for example — you must sometimes use clever workarounds like this one posted on Stackoverflow. That’s because HTTP is a request-response protocol. It requires a request to be sent and a response to be received. It has no concept of a one-way message without any form of response.

RSocket takes a different approach. RSocket defines a new protocol layer on top of transports like TCP and WebSockets. This new protocol offers greater choice to developers, with built-in support for four distinct interaction models:

Spring Cloud Data Flow 2.4.2 GA Released

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 metrics, etc.,

Spring Tips: Java 14 (or: Can Your Java Do This?)

Hi, Spring fans! Welcome to another installment of Spring Tips! In this installment, we’re going to look at the new features in Java 14 and their use in building Spring Boot-based applications.

Speaker: Josh Long (@starbuxman)

To get started, we need to use the latest and greatest version of Java, Java 14, which isn’t - just yet - released yet. It is due to be shipped in early 2020. You can download early access releases on You might also consider using SDKManager (sdk), which makes installing new JVM editions a trivial matter indeed.

This Week in Spring - March 10th, 2020

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 to it!

Getting Started With RSocket: Spring Boot Client

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.
