This Week in Spring - October 22nd, 2019

Engineering | Josh Long | October 22, 2019 | ...

Hi, Spring fans! What a week! I've just returned from Prague, the Czech Republic, where I was for the epic Geecon Prague 2019 event. (Thanks for voting my talk on Reactive Spring the #1 talk, Prague!). Now I'm in Nantes, France, the DevFest Nantes show. I'd never been to Prague and I've never been to Nantes. So how's that for cool first-time appearances in one week? I'll be speaking about testing here. Tonight I fly to Paris, Fr, for customer meetings. Then I fly on Thursday to St. Petersburg, Russia, for the Joker conference, where I'll be presenting on testing and I'll be co-presenting with…

The Reactive Revolution at SpringOne Platform 2019 (part 2/N)

Engineering | Josh Long | October 22, 2019 | ...

Last year right in the middle of SpringOne Platform 2018, I posted the first post in this series, _ The Reactive Revolution at SpringOne Platform 2018 (part 1/N)_, which looked at some of the big features we'd just dropped at SpringOne Platform 2018. I wanted to follow up and revisit that blog and the concepts I'd introduced last year, and show just how far we've come in the intervening year. TL;DR: things are much easier!

R2DBC

Last year, we announced our work on trying to support a standard for reactive SQL data access with a new project called R2DBC. Traditional approaches to SQL data…

Spring Cloud Stream - functional and reactive

Engineering | Oleg Zhurakousky | October 17, 2019 | ...

In the previous post, I tried to provide justification for our shift to a functional programming model in Spring Cloud Stream (SCSt). It's less code, less configuration. Most importantly, though, your code is completely decoupled and independent from the internals of SCSt.

In this post, I’ll dig a little deeper and summarize the core features of our functional support, specifically around its reactive features.

IMPORTANT: Anything you can do with @StreamListener/@EnableBinding you can also do without it. In other words, the functional support is now feature-compatible with the annotation-based support.

This Week in Spring - October 14th, 2019

Engineering | Josh Long | October 15, 2019 | ...

Hi, Spring fans! WHEW! What a week! Last week was the insane SpringOne Platform 2019 event, from which I am still recovering! Then I flew home, hosted Spring team member and Micrometer lead and friend Tommy Ludwig in San Francisco, and prepared to fly out for meetings and user group appearances on Monday (in Stuttgart, Germany) and Tuesday (in Amsterdam).

I prepared, and got into the Uber going to San Francisco airport when I got a call from my brother saying my 81-year-old dad wasn't doing well (thanks to everyone for the well-wishes!) and was rushed to the hospital. I had to, regretfully…

Simple Event Driven Microservices with Spring Cloud Stream

Engineering | Ben Wilcock | October 15, 2019 | ...

Event driven architecture is great. But without a framework, writing the scaffolding required to work with popular event messaging platforms can be messy. In this post we'll take a look at how Spring Cloud Stream can be used to simplify your code.

The Problem

You just want to write logic for your event driven application, but the boilerplate messaging code can get in the way. Connecting your apps to messaging services is tricky, and if you're an enterprise developer, you probably need to work with multiple messaging technologies (either on-premises or in the cloud).

The Solution

Let a flexible messaging abstraction take care of the complex messaging platform integration so you can concentrate on writing simple clean business logic. Spring Cloud Stream is a great candidate. It unifies lots of popular messaging platforms behind one easy to use API including RabbitMQ, Apache Kafka, Amazon Kinesis, Google PubSub, Solace PubSub+, Azure Event Hubs, and Apache RocketMQ. It even smoothes away any subtle…
