Welcome to another installment of This Week in Spring! It's been a busy week for all of us on the Spring team, as you're about to see! I've just finished my presentation at the epic DevNexus show and now I'm off to visit customers in Hartford and Los Angeles before making my way to the epic ConFoo conference in Montreal, Canada. If you're in the area, be sure to ping me and say hi!

We've got a lot to cover, so let's get to it!

• Reactor project lead Stephane Maldini just announced Reactor 2.5: A Second Generation Reactive Foundation for the JVM. This is a huge part of our continued efforts to better support reactive workloads with Spring.
• We've added a new language, Kotlin, to the Spring Initializr! To learn more check out this great post by Sebastien Deleuze on Developing Spring Boot applications with Kotlin
• Spring Integration and Spring AMQP lead Gary Russell's just announced Spring AMQP 1.6.0 Milestone 1 (and 1.5.4) Available
• Spring REST Docs lead Andy Wilkinson's just announced Spring REST Docs 1.1.0.M1
• last week, Spring Data Couchbase 2.0 went GA, and this week I'm pleased to share a guest post from project lead Simon Baslé introducing …

I was inspired by OpenZipkin contributor and Spring Cloud Sleuth and Zipkin contributor Adrian Cole's epic talk introducing Zipkin to write this particular post. There's so much epic stuff in that talk, so once you're done reading this, go watch that!

Advances in technology and cloud computing have made it easier to stand up and deploy services with ease. Cloud computing enables us to automate away the pain (from days or weeks (gasp!) to minutes!) associated with standing up new services. This increase in velocity in turn enables us to be more agile, to think about smaller batches of…

This is a cross-post blog from Simon BASLÉ from Couchbase. You can find him on twitter (@simonbasle) or github. Learn more about Couchbase and the Couchbase Java SDK on the developer portal. Thanks again, Simon and great job to you and your team! -Josh

Spring Data Couchbase 2.0 is a rewrite of the original Spring Data Couchbase 1.4.x connector. It is based on the Couchbase Java 2.2 SDK and makes heavy use of the new query language N1QL (which was introduced in Couchbase Server 4.0) to offer more features for Spring Data users.

The first Milestone has been released last august, then a Release…

Welcome to another installation of This Week in Spring! This week I'm in beautiful Stockholm, Sweden at the amazing JFokus conference. It's also Shrove Tuesday here in Sweden and the custom is to over-indulge, so as I type this I am eating a Semla. I hope you too enjoy over-indulging on this week's epic roundup!

• the world's worst kept secret is finally announced! We've been developing a reactive runtime for Spring MVC, and you can start to kick the tires! Check out this amazing blog on Spring 5's ambitions for reactive web programming!
• Spring Cloud Stream lead Marius Bogoevici has just announced Spring Cloud Stream 1.0.0.M4 which, among other things, defaults to publish/subscribe semantics, supports a notion of consumer groups, provides a simplified binder SPI, resettable Kafka offsets, and so much more! Check it out!

I received an email recently that asked about how to forward control from a wait-state in an Activiti (which is an open-source BPMN2 workflow engine from Alfresco) to a Spring Integration flow and then resume execution of the Activiti workflow process upon completion of some work in Spring Integration.

To really appreciate why this is useful goal, we need some background.

What is Activiti

Activiti is a business process engine. It's basically a directed graph of nodes (states) that model the states of a complex business process. It keeps track of the progression of work described in a business…

I'm about to start hitting the road again and I'd love to talk to you and your organization if you're near any of the following places and events in February:

• Microchg Conf
• JFokus

Stay tuned, we've got more in the pipeline!

• check out this post on using Spring Boot with the Wicket web framework

Welcome to another installment of This Week in Spring and welcome back from what I hope was a restive, fun new year!

This week, we mark the fifth anniversary of This Week in Spring which Adam Fitzgerald and I started (based on some discussion with Keith Donald in January 2011) fresh from the 2010 holidays.

Since then I've done my level-headed best to publish it every week (no exceptions! no missed weeks!) before midnight in Hawaii on Tuesday, every week, no matter what timezone I find myself in for that week! The world's a big place, so from the perspective of someone sitting in, say, New York City, it may seem sometimes like this blog goes up midday Monday (00:00AM in various Asian countries) or early morning Wednesday (23:59 in Hawaii) - that's a lot of variability! But I assure, you it's always…
