Welcome to another installment of This Week in Spring! This week I am in Munich for the Spring Meetup; Berlin for OSDC; Krakow for Geecon; Barcelona for Spring I/O, and Eindhoven for NextBuild. If you're around, say hi.

As usual, we've got a lot to cover so let's get to it!

• Dr. Mark Pollack just announced Spring Cloud Data Flow 1.2GA!, including the server editions for local, Kubernetes, YARN and Cloud Foundry. This new release is packed with good stuff. I particularly like the support for composed tasks, which lets me orchestrate a flow of tasks as a cohesive unit-of-work. This is ideal for…

On behalf of the team, I am pleased to announce the general availability of Spring Cloud Data Flow 1.2 across a range of platforms

Here are the relevant links to documentation and getting started guides.

• Local: Quick Start, Getting Started Guide

• Cloud Foundry: Getting Started Guide

• YARN: Getting Started Guide

• Kubernetes: Getting Started Guide

Highlights of the 1.2 release:

Composed Tasks

This release introduces Composed Tasks ! This feature provides the ability to orchestrate a flow of tasks as a cohesive unit-of-work. A complex ETL pipeline may include executions in sequence, parallel, conditional transitions, or a combination of all of the above. The composed task feature comes with DSL primitives and an interactive graphical interface to quickly build these type of topologies more easily. You can read more about it from the reference guide…

We are pleased to announce that Spring Batch 4.0.0.M2 is now available via Github and the Pivotal download repository. This release represents the second milestone for the Spring Batch 4.0 release. Many thanks to all that contributed to this release.

What's new?

This milestone continues the work laid out in Spring Batch 4.0.0.M1. Specific updates include:

• Dependency updates
• Continued java configuration improvements

Dependency updates

Spring Batch 4 will be the version included in Spring Boot 2 so we're taking this time to syncronize our dependencies. With that, this release supports upgrades to the latest milestones of the Spring Data Kay release train and Spring Integration 5…

It's my pleasure to announce that Spring REST Docs 1.2.1.RELEASE is available from Maven Central, JCenter, and our release repository. My thanks to everyone who contributed to this release by reporting bugs and opening pull requests.

This maintenance release includes a handful of bug fixes and documentation improvements. It is a recommend upgrade for all Spring REST Docs users.

On behalf of the community, I'm pleased to announce the release of Spring Security 5.0.0 M1. This release includes bug fixes, new features, and is based off of Spring Framework 5.0.0 RC1. The highlights of the release include:

• Initial Support for Reactive Web Applications
• New Support for OAuth 2.0 and OpenID Connect 1.0

Initial Support for Reactive Web Applications

Following one of the primary themes of Spring Framework 5.0, Spring Security 5.0 will add support for Reactive applications by building on top of Spring's reactive support. The first milestone focused on getting primary…

On behalf of the community I’m pleased to announce the release of Spring Session 2.0.0.M1. This release is focused primarily on ensuring compatability with Spring Framework 5 which is the minimum Spring version required.

Supported Data Stores

We have also removed some of the Spring Session implementations from the main repository. The goal is to allow the core Spring Session team to focus on delivering new features rather than needing to know the ins and outs of every data store. This will allow development of other modules to be done without the overhead of reviews from the Spring Session…

Introduction

It has been almost 10 years now since I taught my first Core Spring class. At that time almost everything was XML and configuring JPA or Spring Security, for example, could be a lot of hard work. Spring has matured a great deal in the meantime with component-scanning, Java Configuration and Spring Boot making it much more fun to use. And the number of Spring Projects has increased considerably.

Pivotal Training continues to enhance our Spring curriculum and introduce new courses - including Spring Boot Developer and Spring Cloud Services. I have provided an overview of these…

Hi Spring fans! This week I'm in Austin, Texas for OSCON; London, UK, for Devoxx UK; and Nice, France for RivieraDev! If you're around, I'd love to talk to you so don't hesitate to say hi!

• InfoQ has a nice post on the new Spring Vault release
• Spring Integration lead Gary Russell just announced Spring AMQP 2.0M4 is now available

• Spring ninja Stéphane Nicoll‏ announced that there is now a starter for Reactive Redis support…

On behalf of the Spring Data team, I’d like to announce the availability of the third milestone of the release train Kay.

The most significant change is an improved naming scheme for CrudRepository. We extracted the store-specific CustomConversions to Spring Data Commons and introduced bi-directional type-based converters to maintain a single API for common conversion code. You can now define converters using lambdas. You need to adopt your code to the renamed methods. MongoDB ships with a renamed annotation for reactive tailable cursors, we renamed @InfiniteStream to @Tailable. Users of…
