SpringOne2GX 2014 - Day 2

Day 2's kicked off with a bang! My theory is that by that point people had seen a day's worth of sessions, and so the keynote needed to be full of impactful, big-bang announcements and discussions in order to remain memorable. It needed to raise the bar and demonstrate leadership. And it did.

Spring Framework 4.1

Spring framework lead Juergen Hoeller kicked things off with an introduction to the new featues in the recently-released Spring 4.1.

Spring Framework 4.1 provides annotated JMS listener methods, comprehensive for the final JSR 107 specification, flexible resolution and transformation of static web resources, additional MVC views (like Groovy Server Pages), websocket-support improvements, and many more new features.


SpringOne2GX 2014 - Day 1

SpringOne2GX kicked off with a bang on Monday night!

"The Ebb and Flow" of Development

The keynote kicked off with Pivotal's own SVP of R&D, Hugh Williams (formerly of e-Bay and Microsoft research) who talked about the ebb (the awkward interruptions in momentum) and flow of software development. Hugh touched on his prior lives at Microsoft (where he helped develop the Bing search engine) and at eBay (a huge Spring user, we learned!) and spoke about what Spring brings to the table: the ability to be nimble, agile.


This Week in Spring (SpringOne2GX 2014 edition!) - September 9, 2014

Welcome to another installment of This Week in Spring, live from SpringOne2GX 2014! This year's show is something to behold! We kicked off the show yesterday with one amazing keynote here in the "lone-star state" featuring Pivotal SVP of engineering Hugh Williams, the Spring team leads Juergen Hoeller, Dave Syer, Graeme Rocher and and Netflix's Andy Glover.

We'll do some recap blogs, of course, so stay tuned. Before we get started with this week's roundup, check out this video of the SpringOne2GX 2014 logo being projected onto the Dallas Omni hotel!

Spring for Apache Hadoop 2.1.0.M1 Released

One year ago we released the first milestone release of the Spring for Apache Hadoop version 2.0 project, just in time for SpringOne 2GX 2013. To keep up the tradition, we are pleased to announce the first milestone release of Spring for Apache Hadoop 2.1, just in time for SpringOne 2GX 2014 in Dallas, TX. The release is now available in the Spring IO repository

Main changes for the 2.1.0.M1 release:

  • Added support for append mode in store writers
  • Enhancements for kerberos configuration for secured cluster access
  • Support for container grouping and clustering in Spring YARN, which brings functionality for running multiple container types, a new REST API and an improved application model with new client side commands and a command line shell.
  • Starting with this version we support Hadoop 2.0 APIs but no longer provide backwards compatibility with older Hadoop v1 distributions.

Spring Boot 1.2.0.M1 Available Now

I am pleased to announce that Spring Boot 1.2.0.M1 is available now in the Spring milestone repository. This release builds on Spring Framework 4.1 and provides a number of improvements and new features. Highlights include:

  • Support for distributed JTA transactions across multiple XA resources using either an Atomkos or Bitronix embedded transaction manager or a full Java EE Application Server.
  • Easier configuration of JNDI bound DataSource and ConnectionFactory beans.
  • Improved JMS support, including auto-configuration for the Spring Framework 4.1 @EnableJms annotation.
  • Auto-configuration support for spring-cloud.
  • Easier SSL configuration for both Tomcat and Jetty.
  • Improved DataSource Metrics and Health Indicators.

We are pleased to announce that the Java DSL for Spring Integration 1.0 Milestone 3 has been released. Please use the Milestone Repository with Maven or Gradle, download a distribution archive, or see the project home page for more information.

Since the last Milestone 2, some new features and further improvements, as well as a number of bug fixes have been included to this Milestone, with the GA release due around the end of October.

First of all thanks for all who are interested in this Spring Integration Extension, provide feedback, share their thoughts and even contribute.

Join us at the Spring Data birds-of-a-feather session @springone2gx #s2gx

Are you ready for SpringOne? It's almost here!

A popular part of SpringOne are the birds-of-a-feather sessions. Different groups get together to talk about different aspects of Spring, Groovy, and Grails. This year, they are scheduled for Tuesday night, September 9th, starting at 9pm. (When do they end? When everyone finally leaves!)

They are indeed popular. Last year I sat in on the Spring Framework one and enjoyed the close, unscripted discussions (not lectures). You should think about carving out some time for that!


Spring AMQP (for Java) 1.4 Milestone 1 Available

We are pleased to announce that the first milestone of Spring AMQP 1.4 is now available.

Key Features

  • Annotation-based message listeners (@RabbitListener), enabled with either @EnableRabbit or <rabbit:annotation-driven /> (see below for an example).
  • RabbitMessagingTemplate allowing interaction with RabbitMQ using spring-messaging Message objects.
  • A new factory bean to ease the configuration of SSL with the RabbitConnectionFactory
  • Log4j Appender now supports configuration of message persistence.

Here is a simple example for a POJO service using the new annotations:
