Spring Data release train Hopper SR2 released

Releases | Mark Paluch | June 15, 2016 | ...

On behalf of the Spring Data team I’d like to announce the availability of the second service release of the Spring Data Hopper release train. The release ships 103 issues fixed. We fixed a couple of bugs in the area of repository projections, especially for JPA users and introduce Hibernate 5.2 compatibility with this release (also already back-ported to the Gosling release train for inclusion in the upcoming service release). Hopper SR2 is a recommended upgrade for all Hopper users and also users of previous release trains.

Here are the released modules:

Spring Cloud Brixton.SR1 is available

Releases | Spencer Gibb | June 14, 2016 | ...

On behalf of the team, I am pleased to announce that Service Release 1 of the Spring Cloud Brixton Release Train is available today. The release can be found in our Spring Release repository and Maven Central.

This is primarily a bug fix release with a few small features. Of particular note is a change that allows Brixton Eureka Servers to work with Angel Eureka clients.

The following modules were updated as part of Brixton.SR1:

Spring Integration 4.3 GA is Available

Releases | Artem Bilan | June 14, 2016 | ...

Dear Spring community,

I’m pleased to announce that Spring Integration Framework 4.3 GA is now available from repo.spring.io, as well as Maven Central! Also the maintainance 4.2.8 version has been released, too. Together with an internal 4.2.7 release it includes some important bug fixes.

In addition to the feature themes mentioned in 4.3 RC1 announcement, the GA release includes several major changes:

  • Upgrade to Spring Framework 4.3 GA, Spring AMQP 1.6 GA, Spring Security 4.1 GA;

  • The FtpRemoteFileTemplate now provides ExistsMode option to control how an exists() operation should work;

  • The FileSplitter lets represent FileMarker object as a JSON string (markersJson option) to avoid an additional spring-integration-file dependency on the consumer applications in distributed environments;

  • A new JdbcLockRegistry feature has been introduced. Special thanks to Dave Syer!

  • The Integration Graph has been improved with generic gateway nodes and LinkNode now has a type (input, output, error, discard, route) property for better visualization experience;

Notes on Reactive Programming Part II: Writing Some Code

Engineering | Dave Syer | June 13, 2016 | ...

In this article we continue the series on Reactive Programming, and we concentrate on explaining some concepts through actual code samples. The end result should be that you understand a bit better what makes Reactive different, and what makes it functional. The examples here are quite abstract, but they give you a way to think about the APIs and the programming style, and start to get a feel for how it is different. We will see the elements of Reactive, and learn how to control the flow of data, and process in background threads if necessary.

Setting Up a Project

We will use the Reactor libraries to illustrate the points we need to make. The code could just as easily be written with other tools. If you want to play with the code and see it working without having to copy-paste anything, there are working samples with tests in Github

Spring Framework 4.3 goes GA

Releases | Juergen Hoeller | June 10, 2016 | ...

Dear Spring community,

I'm pleased to announce that Spring Framework 4.3 GA (a.k.a. 4.3.0.RELEASE) is now available from repo.spring.io as well as Maven Central!

In addition to the feature themes mentioned in my 4.3 RC1 announcement, the GA release covers compatibility with several recent third-party releases, in particular: Hibernate ORM 5.2, Jackson 2.8, Netty 4.1, Undertow 1.4, and Tomcat 8.5.2 / 9.0 M6. Also, please note that our Hibernate 3.x support is finally deprecated (even Hibernate 4.x is not actively supported by Red Hat anymore) and that Spring 4.3's Jackson support requires…

Spring Cloud Stream 1.0.2.RELEASE is available

Releases | Marius Bogoevici | June 08, 2016 | ...

Shortly after the 1.0.1.RELEASE announcement last week we’ve identified a critical and very specific issue concerning multi-binder configurations in cloud environments. As a result, we have decided to follow up with a 1.0.2.RELEASE to handle that and ensure that the fix is available in the upcoming Brixton.SR1 release. The artifacts can be found in Spring Repository as well as Maven Central.


I will be talking about Spring Cloud Stream at Spring One Platform, which will be taking place in Las Vegas between August 1-4 this year. There are many other great talks so check the agenda and get your ticket if you haven’t done so…

Welcome to another installment of This Week in Spring! It's already June! Where. Does. The. Time. GO?? This week I'm in Chicago, IL, for the Chicago Coder Conference, Boston and New Hampshire for customer visits, London, England for Devoxx UK and Talin, Estonia for Geekout EE. If you're around be sure to say hi! Now then, we've got a lot to cover this week so let's get to it!

Introducing Spring Cloud Cloud Foundry Service Broker

Releases | Scott Frederick | June 07, 2016 | ...

I am pleased to announce the newest addition to the Spring Cloud family. Spring Cloud Cloud Foundry Service Broker is a framework for building service brokers for the Cloud Foundry platform.

Cloud Foundry service brokers

Service brokers provide a means to extend Cloud Foundry with managed services that can be consumed by applications deployed to the platform. Managed services typically expose some sort of resource to an application, such as a database or other persistent store, a messaging system, or other supporting infrastructure. Service brokers publish a catalog of services and service…

Notes on Reactive Programming Part I: The Reactive Landscape

Engineering | Dave Syer | June 07, 2016 | ...

Reactive Programming is interesting (again) and there is a lot of noise about it at the moment, not all of which is very easy to understand for an outsider and simple enterprise Java developer, such as the author. This article (the first in a series) might help to clarify your understanding of what the fuss is about. The approach is as concrete as possible, and there is no mention of "denotational semantics". If you are looking for a more academic approach and loads of code samples in Haskell, the internet is full of them, but you probably don’t want to be here.

Reactive Programming is often…
