Welcome to another installment of This Week in Spring! This week I'm in warm 'n wonderful Austin, TX to meet with customers and then off to Mexico City, Mexico to present the keynote at a the SG Conference and Expo. If you're in Mexico City y si le gustaria hablarme sobre todos las cosas Spring y la informatica, sere a Mexico City desde miercoles. No hesita a contactarme en Twitter (@starbuxman)!

It's June 30th! Whew this year is flying! We've got a lot to cover this week so let's get to it!

• Spring framework lead Juergen Hoeller just announced Spring framework 4.1.7 and 3.2.14, both of which are maintenance releases
• Spring framework ninja Stephane Nicoll just announced Spring framework 4.2 RC2, packed with lots of new features!
• Spring Tool Suite lead Martin Lippert just announced updates version 3.7.0. The updates include Eclipse Mars 4.5 GA, Spring Boot YML support, improved Cloud Foundry integration, Pivotal tcServer 3.1.1 support, and early support for Spring Roo 2.0.0.M1 (thanks to Disid).
• the good Dr. Syer, co-founder of the Spring Boot and Spring Cloud projects, just announced the first Spring Cloud release train, Angel.SR3…

The latest version of Spring Cloud is "Angel.SR3" and it is available now from the usual repositories (note the new naming convention, more detail below). Most components are now at 1.0.2.RELEASE, but spring-cloud-netflix is at 1.0.3.RELEASE. The starters and cli and also at 1.0.3.RELEASE, reflecting their dependency on Netflix. Angel.SR3 is a bugfix release for Angel.SR2 (formerly known as 1.0.2) and all existing projects are encouraged to upgrade to take advantage.

There are a few new features, the biggest of which is the new naming convention for the starter parent project (see below…

I'm delighted to announce that Spring REST Docs has reached its first milestone and that 1.0.0.M1 is available from https://repo.spring.io/milestone.

Spring REST Docs helps you to document RESTful services. It combines hand-written documentation written with Asciidoctor and auto-generated snippets produced with Spring MVC Test. This approach frees you from the limitations imposed by tools like Swagger. It helps you to produce documentation that is accurate, concise, and well-structured. This documentation then allows your users to get the information they need with a minimum of fuss.

Welcome to another installment of This Week in Spring! I was in London, last week, for Devoxx UK. The show was a rousing success all around. I gave a talk, a workshop, and was delighted to participate in the closing keynote, too! This week I'm in Kraków, Poland, for Devoxx Poland (né 33rd Degree) which seems to be an amazing success as well! I want to thank the organizers (Mark Hazell and Grzegorz Duda of Devoxx UK and PL respectively) for inviting me - I haven't had this much fun in a while and I love the communities that both events serve.

In addition to being in the keynote, I was…

We are pleased to announce the release of Spring Integration Kafka 1.2.

This new release provides a couple of major improvements and upgrades over the previous versions:

• Support for Apache Kafka 0.8.2 and using the new Producer API;
• Overhaul of the internal concurrent dispatching with a non-blocking ring buffer implementation based on Project Reactor.

For each of the changes, the goal was to improve the performance of the producer and, respectively, consumer components of Spring Integration Kafka. While we do not have any isolated benchmarks for Spring Integration Kafka proper, the enhancements of the release have contributed to the performance metrics reported in the newly released Spring XD 1.2…

Perhaps you've noticed some recent articles lately?

• Spring 5 moving up to Java 8+
• Massive adoption of Spring 4 and Java 8
• http://start.spring.io/ defaulting to Java 8 as the version of choice
• Spring Boot's 1.3.0.M1 reference docs recommending new apps start at Java 8.

Okay, those last two aren't articles, but were instead driven by the the rapid adoption of Java 8. Java 8 has been picked up by the development community FAST. Here on the Spring team, we believe strongly in adopting Java 8 for new applications. To support that and improve your own ability to move as well, we just updated all of the Spring Getting Started Guides…

Today, we are pleased to announce the general availability of Spring XD 1.2, Spring XD 1.1.3 and the release of Flo for Spring XD Beta.

• 1.2.0.GA: zip
• 1.1.3.RELEASE: zip
• Flo for Spring XD Beta

You can also install XD 1.2 using brew and rpm

The 1.2 release includes a wide range of new features and improvements. The release journey was an eventful one, mainly due to Spring XD’s popularity with so many different groups, each with their respective request priorities. However the Spring XD team rose to the challenge and it is rewarding to look back and review the amount of innovation delivered to…

#Introduction#

A common question when developing streaming applications is, “How many events per second can you process?”. The primary purpose of this blog post is to answer that question without falling into the classic benchmarking conundrum of benchmarking versus "benchmarketing". The common approach with 'native' benchmarking applications provide by messaging middleware vendors is to focus on raw data transport speed, without serialization or deserialization of the message data and without any data processing. In Part 1 of the series, we will follow this approach.

Our tests used direct…
