Happy new year! I hope your new year and holidays were amazing. And, welcome back to another installment of This Week in Spring.

This year is going to be <EM>incredible</EM>, so let's dive right into it.  



This week's  roundup features some content from the last few weeks. Particularly, we've got content that InfoQ   put up     
from the <a href = "http://www.springone2gx.com">SpringOne2GX 2011</a> conference.  

Thank you InfoQ for sharing this great content, as usual.

1. Garry Russel and David Turanski's SpringOne2GX presentation on implementing highly available architectures using Spring Integration is now up on InfoQ.

<LI> Rob Winch demoes some of the <A href = "http://www.infoq.com/presentations/Spring-Security-3-1">new features in Spring Security 3.1</a>: multiple http elements, stateless authentication mode for RESTful services, Debug Filter, CAS support for…

Today we're happy to announce that the Spring Framework has moved to GitHub!

As you've probably noticed, nearly every other Spring project has already made the move, and those that haven't will soon.

Git helps us with many of the challenges of managing a large codebase like the Spring Framework, but what's most exciting is what GitHub means for the Spring community. Many readers will already know the virtues of watching and forking repositories, pull requests, forking and editing, and the many other features that GitHub adds to the already excellent world of Git. If you're new to this stuff, be sure to check out the great materials at help.github.com…

		Well, it's that time of the year again!  

The holiday season is upon us and many people will be celebrating! No matter what holiday you're celebrating (or if you're celebrating at all), let me wish you a wonderful week and the happiest of holidays.
To tide you over we've packed this week's roundup to the brim.
Enjoy!

1. Santa's elves could learn a thing or two from the SpringSource engineers! Alan Stewart announced Spring Roo 1.2.0 GA on Saturday. This version of Roo has caught the attention of a lot of people. While there are many new features, some of my favorites are the multi-module Maven project support (which lets you, for example, build your model classes in a separate project from your web application), support JSF / PrimeFaces scaffolding (as opposed to just GWT, Spring MVC, Vaadin, and Flex), support for services / repositories (using Spring Data JPA and Spring Data MongoDB; this is in addition to the Active record style data-access objects…

Amidst the flurry of Spring releases this month, Spring Python has it's own.

Versions 1.1.1 and 1.2.1 are maintenance releases that patch some bugs. Version 1.3.0.RC1 is the first release of 1.3.0.

In this release we have commits from team members, and have also merged pull requests through github. If you want to make contributions to this project, don't forget to sign the contributor license agreement.

Thanks,

The Spring Python team

It is my pleasure to announce that Spring Roo 1.2 GA has just been released. This release represents a significant amount of engineering effort by the Roo team and includes all the most popular features that the Roo user community have requested as well as many performance and usability improvements. The new features of Roo 1.2.0 are:

• Apache 2.0 licensed
• Multi-module Maven project support
• JSF / PrimeFaces scaffolding
• Services / repositories (using Spring Data JPA and Spring Data MongoDB)
• Database reverse engineering multi-schema support
• Flexible GWT support
• Shell usability improvements

In my next blog coming soon, I will detail the new commands available to use these exciting new features.

Welcome to this final Countdown to Grails 2.0 post: the final release is imminent! I'm not really going to say much here because some of the most interesting new features of Grails 2.0 are much better seen. For that reason, I've created a screencast so you can see exactly what awaits you when you install Grails 2.0 for the first time:

http://www.youtube.com/watch?v=KJMR0gB6NHk

The key aspects are:

• a whole new interactive console;
• better automatic class reloading, including support for domain classes and Java files;
• enhanced error reporting;
• new HTML 5 scaffolding; and
• new test reports.

As shown in the screencast, the new interactive console comes with: auto-completion on commands; execution of external applications using "bang" (!) commands; a command history buffer; and easy access to test and dependency reports. This is backed up by a much improved reloading mechanism for Grails classes. You don't need to restart run-app…

Today saw the release of the Spring framework, version 3.1, the next step in enterprise Java development.

  	There is a <EM>lot</EM> of other stuff to talk about this week, but we'll
  	forego them for next week, because there's quite simply too much to look at with Spring 3.1.  

  	Take a look at the following content, and don't forget to download (<A href="http://www.springsource.com/download/community?project=Spring%20Framework&version=3.1.0.RELEASE">direct</a> or <a href="http://www.springsource.org/spring-core#download">maven</a>) and try out the latest and greatest bits today! 
 

And, of course, for all the gritty details of what's new, check out the Spring Framework 3.1 release notes.

Among my favorite new features in this release:

<ul> <LI>
Comprehensive Java-based application configuration</LI>
</LI> <lI>New caching abstraction
</LI…

It is my pleasure to announce that Spring Framework 3.1 becomes generally available today! This release delivers several key features that make Spring ready for the challenges of 2012 and beyond:

• The environment abstraction and the associated bean definition profiles, along with centrally configurable property sources for placeholder resolution.

• Java-based application configuration based on @Enable* annotations on configuration classes, allowing for convenient container configuration: e.g. using @EnableTransactionManagement to activate declarative transaction processing.

• The cache abstraction with our declarative caching solution (@Cacheable etc) on top, focusing on convenient interaction between application code and cache providers.

• The Servlet 3.0 based WebApplicationInitializer mechanism for bootstrapping a Spring web application without web.xml! This is a key piece in Spring's web configuration story, providing a rich alternative to XML-based bootstrapping.
