Spring Boot for Apache Geode & Pivotal GemFire 1.3.0.M3 Released

On behalf of the Spring, Apache Geode & Pivotal GemFire communities, it is my pleasure to announce the release of Spring Boot for Apache Geode & Pivotal GemFire (SBDG) 1.3.0.M3. This release builds on Spring Boot 2.3.0.M3 and is available in the Spring Milestone Repository.

You can also create a new Spring for Apache Geode project with the 1.3.0.M3 bits using Spring Initializer at start.spring.io.

What’s New

SBDG 1.3.0.M3 builds on Spring Boot 2.3.0.M3, which pulls in Spring Framework 5.2.4.RELEASE, Spring Data Neumann-M4, Spring Session Dragonfruit-M2 with Spring Session for Apache Geode & Pivotal GemFire (SSDG) 2.3.0.RC1 specifically, and Spring Test for Apache Geode & Pivotal GemFire (STDG) 0.0.13.RELEASE.

In addition, the following changes were made:

  • New reference documentation Look-and-Feel. Special thanks to Rob Winch for helping out with this one!

  • Adds ability to run SBDG Samples (for now, just the Getting Started Example) independently using Maven as well as Gradle.

  • Fixes bug in auto-configuration when TLS is enabled in a cloud managed environment (e.g. PCP.

Getting Started With RSocket: Spring Boot Request-Stream

Time: about 15 minutes.

Previously in this series, you experimented with request-response and fire-and-forget messaging in Spring Boot with RSocket. This time you’ll try another of RSocket’s fresh new messaging models — request-stream.

In this exercise, you’ll learn how to stream data using the conventional ‘client-requests-a-server-stream’ approach.

One thing that I haven’t mentioned until now is that RSocket lets you use its messaging models in either direction. Therefore, if you wanted to use the less common ‘server-requests-a-client-stream’ model, that’s no problem for RSocket. Plus, there are lots of non-java RSocket implementations to choose from, including Go, Javascript, and .Net—ideal if your architecture includes platforms where Java isn’t perhaps the best fit.

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:
