Dear Spring Community,

We are pleased to announce the second milestone release of Spring Social 1.1.0!

Spring Social is an extension of the Spring Framework that enables you to connect your Java applications to Software-as-a-Service (SaaS) providers such as Facebook and Twitter.

Along with Spring Social 1.1.0, we are also releasing second milestones for Spring Social Facebook 1.1.0 and Spring Social Twitter 1.1.0.

The main theme of milestone 2 is tighter integration with Spring Security, including a new SocialAuthenticationFilter to achieve sign-in-with-provider capability directly within the Spring Security filter chain.

In addition to Spring Security integration, these milestone releases also include:

• Support for non-standard parameters in the OAuth authorization flows.
• Interceptor capability in ProviderSignInController's flow to allow for custom behavior in authentication flow.
• Sign-in capability for Facebook Canvas applications, including a new spring-social-canvas sample to showcase the use of CanvasSignInController.
• Support for paging in the Facebook API binding with "since" and "until" parameters.
• Advanced search capabilities in the Twitter API binding.
• Support for ticker symbol pseudo-entity in Twitter statuses.

These milestone releases also contain several smaller improvements and bug fixes.

To get the software, download the release distribution (Core | Facebook | Twitter).

As always, the Spring Social community has been awesome at providing feedback and contributing pull requests to make this release possible. Significant contributions in this release came from Stefan Fussenegger, who contributed much of the Spring Security integration code and Yuan Ji who provided feedback and refactoring help in that same set of code. Also, it seems that the Spring Social community has taken a keen interest in using Spring Social to build Facebook Canvas apps, which led to the creation of CanvasSignInController.

If you'd like to follow along or contribute, we encourage you to participate in the Spring Social Forum, report bugs or suggest enhancements, or to fork the code and contribute back via pull requests.

I am pleased to announce the first themed release of the Spring Data release train named Arora. Going forward we'll use names of famous computer scientists to label a set of Spring Data modules to make it easier to identify modules being compatible to each other. This mostly refers to the Spring Data Commons version they refer to.

The Arora release contains the following modules:

• Spring Data Commons 1.5 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data JPA 1.3 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data MongoDB 1.2 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data Neo4j 2.2 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data Redis 1.0.3 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data Gemfire 1.3 M1 - Artifacts - JavaDocs - Documentation - Changelog
• Spring Data Solr 1.0 RC1 - Artifacts - JavaDocs - Documentation - Changelog

The major new features of the release are:

• Annotation based auditing support through @CreatedDate, @CreatedBy etc. (except Spring Data Gemfire)
• Exposure of Spring Data Mapping information for all modules (to be used by Spring Data REST)
• Spring Data Mapping information being read from accessor methods as well
• Automatic registration of JodaTime Converters if present on classpath (Spring Data MongoDB)
• Major improvements to mapping subsystem and query execution for Spring Data MongoDB
• Extended querying options on query methods (Spring Data Solr)
• Annotation support for Gemfire functions (Spring Data Gemfire)
• A tag has been added to the gfe-data XML namespace for automatic basic client connection and region configuration. (Spring Data Gemfire)
• Support for Lettuce Redis driver (raising the count of supported driver to 5, Spring Data Redis)
• Dynamic removal of listener for running MesageListenerContainer (Spring Data Redis)
• Refined Maven build to ease release process

Alongside the new major versions of the Spring Data Modules we've also published bugfix releases for Spring Data Commons (1.4.1), Spring Data JPA (1.2.1) and Spring Data MongoDB (1.1.2).

Note: The artifactId of the Spring Data Commons module has changed to from spring-data-commons-core to spring-data-commons. So if you're explicitly referring to it from your project, make sure you update the reference accordingly.

The binaries will be present in Maven central shortly if not already in place.

Dear Spring Community,

I'm happy to announce the release of Spring Social Twitter 1.0.3.RELEASE.

Spring Social is an extension of the Spring Framework that enables you to connect your Java applications to Software-as-a-Service (SaaS) providers such as Facebook and Twitter.

This is an API-update release, bringing Spring Social Twitter's API binding up to date with version 1.1 of Twitter's API. Twitter has deprecated the 1.0 version of their API and will shut it down next month. It is recommended that if you are using Spring Social Twitter 1.0.2 or lower that you immediately upgrade to Spring Social Twitter 1.0.3 to avoid any disruption in functionality.

To get the software, download the release distribution.

It is anticipated that this will be the last release of Spring Social Twitter in the 1.0.x series. Work on Spring Social 1.1.0 is well underway and is now at milestone 2 for the 1.1.0 release.

A minor maintenance release of Spring Web Flow 2.3.2 is now available via Maven and for download. See the Changelog for the list of changes.

A first milestone of Spring Web Flow 2.4 is also available through the SpringSource milestone repository. See the Changelog for the full list of changes.

Spring Web Flow samples have been separated from the distribution and into a separate Github project. In addition the booking-mvc sample has been updated to use Thymeleaf thanks to Thymeleaf's project lead Daniel Fernández.

Welcome back to another installation of This Week in Spring ! I've been visiting developers and companies in India, China, and Japan. It's been an exciting time to see what these emerging and powerful countries are doing with open source and with Spring, in particular! Of course, stay tuned to the SpringSource blog in the coming weeks some very cool examples and details!

In the meantime, as usual, we've got quite a bit of news to cover this week, including more news on the Spring 4 roadmap announcement from last week. If you want to get the absolute latest, check out the Spring 3.2 GA webinar replay on YouTube, where Spring Framework 4.0 is covered a bit toward the end. Let's get to it!

1. Charles Humble at InfoQ's done a nice interview with Juergen Hoeller and write up of the Spring 4 announcement .
2. The Spring Integration 2.2.1 and 2.1.5 maintenance releases are now generally available.

		<LI>Spring HATEOAS 0.4 was <a href="http://www.springsource.org/node/3796">released</a>, adding Jackson and HAL support.</LI>

3. Two new SpringOne 2GX 2012 Replays have been released to our YouTube Channel: Tooling for the Javascript Era, An Introduction to Broadleaf Commerce
4. We've launched a page to centralize all the SpringOne2GX 2012 recordings, check it out!
5. Chris Beams, Gunnar Hillert, and Rossen Stoyanchev were recorded in well-received presentation Introducing WebSockets at SpringOne2GX 2012, now online on InfoQ!
6. Blogger Ilias Tsagklis from the Java Code Geeks blog also has a nice post on the Spring 4.0 roadmap announcement.
7. Chris Beams has announced that Spring 3.1.4 has been released!
8. Marty Pitt has created a very nice extension - he's calling it BakeHouse- for Spring web applications that preprocesses web artifacts for consumption in your web application at application startup. There are various kinds of pre processing possible:
   • Less for your CSS
   • Concatenate and minify your Javascript
   • Maybe even use some Typescript or CoffeeScript, which needs to be compiled
   This is a very cool extension, Marty! It's like what I always wanted things like JAWR to be! The thing I most like about it, though? The fluid use of Spring Java @Configuration classes! Really slick and productive!
9. The Japanese portal Public Key has a nice writeup of the announced roadmap for Spring 4.0
10. The Just Enough Architecture blog has a nice post on using ActiveMQ, Spring Integration and MongoDB together - cool! I might've used Spring Batch's flat file reading support instead of a custom one out of the box, though, overall, this is an awesome post!
11. Blogger madhav has a nice look at the code to support table and class inheritance using Spring Data JPA. That said, it's really hard to read as the code is not indented at all!
12. Noushin Bashir has put together a nice post on how to configure ActiveMQ with SSL and then connect to it from Spring.
