Welcome to another installment of This Week in Spring! This last week was a bit crazy, though after a long restful weekend there's a lot of intersting content to invigorate us for the week ahead. I'll be speaking at a meetup on the 16th June, for those near Amsterdam that'd care to join us! As usual, we've got a lot to cover so let's get into it.

• Remember, the goal of microservices is, ultimately, to go faster and to get to production. To do continuous delivery. A huge part of that has to be moving code from integration and testing to production, automatically, and ideally with no downtime. I'd recommend this excellent blog by Spring Cloud team member Marcin Grzejszczak on zero-dotime deployments with a database. This is an excellent resource!
• speaking of micrservices and Spring, there's a neat introduction to doing microservices "Spring Boot way" (is there any other way? :D) on DZone by Santosh Singh
• want to learn more about Kotlin and Spring? Want to see why large organizations (like Netflix) are using Spring Cloud along with Kotlin? check our Spring team member Sébastien Deleuze's spring-kotlin…

This article will explain in depth how to tackle issues related to database compatibility and the deployment process. We will present what can happen with your production applications if you try to perform such a deployment unprepared. We will then walk through the steps in the lifecycle of an application that are necessary to have zero downtime. The result of our operations will be applying a backward incompatible database change in a backward compatible way.

If you want to work through the code samples below, you will find everything you need in GitHub.

Introduction

Zero downtime deployment

What is this mythical zero downtime deployment? You can say that your application is deployed that way if you can successfully introduce a new version of your application to production without making the user see that the application went down in the meantime. From the user’s and the company’s point of view it’s the best possible scenario of deployment since new features can be introduced…

Welcome to another installation of This Week in Spring! This week's already off to a crazy start. Sunday evening I returned from Kiev, Ukraine, where I spoke at JEEConf. Yesterday, Monday, I gave a talk with my friend Baruch from JFrog at yesterday's JFrog Swampup conference event in Napa, California. Today I'm off to Denver, Colorado for Gluecon, and then off to GOTO Chicago in Chicago, Illinois and I'll finish out the week in Washington DC for customer visits. I can't wait to see you all along the way!

• I hope you'll register for this upcoming webinar on distributed tracing with the Spring Cloud team's very own Adrian Cole and Marcin Grzejszczak
• Wow! Spring Roo 2.0M2 is packed with lots of cool looking features supporting Spring Boot and removing the older ActiveRecord-style support in favor of proper Spring Data repositories
• I really liked Stormpath founder and CTO Les Hazlewood's post on how they moved their entire backend API to Spring Boot in a matter of three weeks while embracing Spring Boot's autoconfiguration to solve a few problems of their own, like a Samza auto-configuration.
• the Udemy Spring Cloud workshop online looks pretty cool…

Welcome to another installment of This Week in Spring! As I write this, I'm in Chennai, India, en route to Bangalore, India for a day of exciting customer meetings and then I'm off to sunny Barcelona, Spain, for the epic Spring IO event! Then, this Friday, I'm off to Kiev, Ukraine, for JEEConf. If you're around, as always, don't be shy and say hi!. That said, let's get into it!

• The BIG news: Spring Cloud Brixton is now available! Get the bits from the Spring Initializr. If you'll permit a little back-patting, I submit that you might get a good feel for what concerns a technology like Spring Cloud addresses by reading this article I wrote and you'll learn how Spring Boot and Spring Cloud are used in this video. That said, grab the bits and go!
• Spring Cloud Stream 1.0.0 is here, at long last! Spring Cloud stream makes it simple to build collaborating messaging-based microservices.
• Spring Boot co-lead Phil Webb just announced that Spring Boot 1.4.0.M3 is now available, just in time…

Auntie Em! Time sure is flying! Welcome to another installment of This Week in Spring! This week I'm in Warsaw for a Cloud Native meetup and Krakow, Poland for the spectacular Geecon event! If you're around, don't hesitate to say hi for Also, some very big news coming! Stay tuned to the Spring.io blog tomorrow! Anyway, as usual, we've got a lot to look at so let's get to it!

• Spring Security lead Rob Winch just announced Spring Security 4.1.0 RELEASE! This is a big release with a lot of cool stuff!

I can't even believe it's May already! STOP THE WORLD I WANT OFF! Well, at least the times are exciting! There's so much cool stuff to look at this week so let's get to it!

• New sessions are up on the shiny new SpringOne Platform website check it out!

As we've just shipped the GA release of Spring Data release train Hopper, let's take a deeper look at the changes and features that come with the 13 modules on the train. A very fundamental change in the release train's dependencies is the upgrade to Spring Framework 4.2 (currently 4.2.5) as baseline. This is in preparation for the upcoming 4.3 release of the framework. We also took the chance to upgrade our Querydsl integration to 4.x (currently 4.1) which required some breaking changes in very core abstractions. Besides that, Hopper contains quite a few significant major version changes its…

I am pleased to announce the release of Spring Data Geode 1.0.0.APACHE-GEODE-INCUBATING-M2, offering support for the recently announced Apache Geode 1.0.0-incubating.M2 release.

Spring Data Geode is a specific version of Spring Data GemFire with support for Apache Geode rather than Pivotal GemFire.

Both Spring Data GemFire and Spring Data Geode are based on the same source repository in GitHub, however, Apache Geode support lives in the apache-geode branch. Therefore, you won't find a separate Spring Data project specifically for Apache Geode, but this is of little consequence since your existing knowledge of Pivotal GemFire combined with Spring Data GemFire will be immediately useful and transferable to Apache Geode and Spring Data Geode…

Following 1.1.0.M1, it's my pleasure to announce that Spring REST Docs 1.1.0.RC1 has been released and is available from https://repo.spring.io/milestone/.

What's new?

HTTPie request snippet

A new HTTPie request snippet has been introduced. Similar to the existing curl request snippet, the new snippet contains the HTTPie command for a request. My thanks to Raman Gupta who contributed this new feature.

Reusable snippets

Snippets can now be created once with some common configuration and then reused. This reduces repetition when documenting common parts on an API, such as self links.

Relaxed…
