Hey guys, welcome to another installment of This Week in Spring! This week I'm in New York City, New York, talking to developers at the NYC Java Meetup and at ScalaDays about Spring. We've got a lot of webinars this month, so be sure to check out the details below!

1. Want a pass to SpringOne 2GX 2013? If you're a Spring champion, show off your stuff on our champions forum and follow these instructions by June 21, 2013. You might be one of our 5 lucky winners! (If you're a Groovy & Grails or Cloud Foundry champion, never fear, we will be rolling out future contests for you!)
2. Oliver Gierke has announced Spring Data Babbage, the first milestone of the next Spring Data release train. This release includes a lot of new features, so be sure to check out the release note!
3. Spring Batch 2.2.0 is now available! This is a major release that supports Spring Data, Java Configuration, AMQP, and SQLFire in addition to a number of other features. Spring Batch and our participation in the expert group has heavily informed the JSR-352 specification that recently has been finalized.
4. Spring Tool Suite and Groovy / Grails Toool Suite 3.3.0 M2 has been released, based on Eclipse Kepler 4.3. This milestone release improves Java Configuration support and is Spring Framework 4 ready.
5. Craig Walls has announced that Spring Social Twitter 1.0.5 and Spring Social 1.0.3 have been released! The new release fixes a few bugs and is being made available in anticipation of the deprecation of the 1.0 version of the Twitter API.
6. Gary Russell has also announced the Spring Integration 2.2.4 and 2.1.6 maintenance releases, to incorporate the Spring Social Twitter updates mentioned above.
7. I'll be doing a webinar on Thursday on RESTful service design with Spring. As usual, there will be two sessions - one at 3PM GMT and one at 10:00AM PST - to accommodate as many timezones as possible. The webinar will introduce Spring's stack for building RESTful services. We'll start with a simple API, then advance the API, introducing Hypermedia controls with Spring HATEOAS, introducing conventions-oriented repository-based APIs with Spring Data REST, security with Spring Security OAuth and Spring Social and addressing common cases like file uploads, exception handling, record paging, and Ajax. I look forward to seeing you there!
8. Don't miss Jon Brisbin on June 18th, 2013 as he introduces Introducing Reactor - A framework for asynchronous applications on the JVM. Reactor provides a foundational framework for applications that need high throughput when performing reasonably small chunks of stateless, asynchronous processing.
9. Join Tony Erksine from Liberty University on June 27th as he instructs us How to talk Spring and Influence People, a pragmatic lesson on soft skills and technology adoption strategies needed to help get other developers in your company excited about,a nd using, new technology -- in this case, with Spring.
10. I gave a talk on the latest at the amazing DevNexus conference in March on Spring 3.1, 3.2, and 4.0 in March, and that talk is now available online on InfoQ. Do check out the talk, but also be sure to check out the more up-to-date version of that deck from my talk at JAXConf available on my SlideShare account.
11. Head over to the Pivotal Blog for a short primer on Hadoop programming, which walks you through a simple word count program. The example looks at the canonical word-count problem and then looks at other solutions in the ecosystem like Pig, Hive and Cascading. The next blog in the series will introduce Spring for Apache Hadoop for a beginning audience, providing a unified, consistent alternative to the four different methods discussed in this blog post.
12. In related news, if you're in the New York City area, join me Wednesday evening where I'm giving the same talk at the 10gen offices for the NYCJava meetup. Thanks again go to 10gen, the company behind MongoDB, for hosting the meetup.
13. The JavaBeat blog has a nice post on how to use Spring's robust multipart file upload support. Spring's support abstracts away common APIs for file uploads - including the commons-fileupload API and the Servlet 3 API - and lets you use those APIs for HTTP miltipart-encoded file uploads, typically in web applications or REST services. Definitely worth a read, check it out!
14. Idan Fridman put together a rundown on some of the common types of components in Spring Integration, including splitters, transformers, aggregators, and more.
15. For those of you who are looking to take your Spring skills to a new level of expertise, SpringSource has just released the Professional Spring Training Schedule for July 2013
16. The Spring tutorials blog has a great post introduce Spring's @Async and @Scheduled annotations.

We are pleased to announce the availability of Spring Integration 2.2.4 and 2.1.6 maintenance releases.

Spring Integration's Twitter module uses Spring Social Twitter, which has been updated to version 1.0.5 in anticipation of the Twitter v1.0 API retirement. The Spring Social Twitter 1.0.4.RELEASE [1] and 1.0.5.RELEASE [2] announcements provide more information about the recent updates to that project. For anyone using Twitter search adapters, the underlying search API in v1.1 requires authorization, so you will need to update the configuration for any TwitterTemplate (if not already…

Head over to the Pivotal Blog for a short primer on Hadoop programming, which walks you through a simple word count program. Learn some basics about Apache Hadoop via four coding approaches:

• using the native Hadoop library
• alternate libraries such as Pig, Hive and Cascading

Stay tuned for the next blog entry in the series, where Spring for Apache Hadoop is introduced for a beginning audience, providing a unified, consistent alternative to the four different methods discussed in this blog post.

Dear Spring Community,

I'm happy to announce the release of Spring Social Twitter 1.0.5.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.

Spring Social Twitter 1.0.5.RELEASE is a bug fix release that addresses a couple of bugs found since 1.0.4.RELEASE. Specifically, the following items have been fixed:

• Spring 3.0.x compatibility issue when creating a TwitterTemplate using an application token.
• Improper deserialization of the max_id property in SearchMetadata.

As with the previous release, Spring Social Twitter 1.0.5.RELEASE is being made available in anticipation of the retirement of version 1.0 of Twitter's API, scheduled to take place tomorrow, June 11, 2013.

To get the software, download the release distribution or change the Spring Social Twitter dependency in your build file to reference 1.0.5.RELEASE.

We invite you to discuss this release as well as the continuing work toward Spring Social 1.1.0 in the Spring Social Forum and to report any bugs or improvements in the Spring Social Twitter issue tracker.

I am pleased to announce the first service milestone release for the Spring Data release train named Babbage. It includes the following modules:

• Spring Data Commons 1.6 M1 - Changelog
• Spring Data JPA 1.4 M1 - Changelog
• Spring Data MongoDB 1.3 M1 - Changelog
• Spring Data Neo4j 2.3 M1 - Changelog

The first milestone includes quite a few new features as well as all the bug fixes already released in the service release for Arora.

A quick tour through the release

Most of the changes of this release have made it into Spring Data Commons to build a solid foundation for the next generation of Spring Data projects and make sure that foundation matures fastly. The other modules released in this train station have been adapted to these changes and thus benefit from them as well.

We've upgraded to Querydsl 3.x APIs to accomodate the changes introduced in their major release. The repositories abstraction has added support for ordering ignoring case as well as count…By…(…) projection for derived queries…

Dear Spring Community,

I'm happy to announce the release of Spring Social Twitter 1.0.4.RELEASE and Spring Social 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.

Spring Social Twitter 1.0.4.RELEASE is being made available in anticipation of the retirement of Twitter API v1.0. Although Spring Social Twitter has supported the v1.1 of the Twitter API since 1.0.3.RELEASE, it required user authorization for all operations. Twitter has since started supporting application authorization (e.g., OAuth 2 Client Credentials Grant) for resources that do not strictly need user authorization (such as search). Spring Social Twitter 1.0.4.RELEASE now offers a new constructor for TwitterTemplate that accepts an application access token for accessing resources that allow application authorization.

In addition, a few minor bugs in the Twitter API binding have been addressed.

In support of the changes in Spring Social Twitter 1.0.4.RELEASE, Spring Social 1.0.3.RELEASE offers a new authenticateClient() method in OAuth2Operations to enable an application to obtain an application access token. This application token can be used to construct a TwitterTemplate through the new constructor.

To get the software, download the release distribution:

• Spring Social Twitter 1.0.4.RELEASE
• Spring Social 1.0.3.RELEASE

We invite you to discuss these releases as well as the continuing work toward Spring Social 1.1.0 in the Spring Social Forum and to report any bugs or improvements in issue tracking (Core | Twitter).

We are pleased to announce that Spring Batch 2.2.0.RELEASE is now available via Maven Central, Github and the SpringSource download repository.

Spring Batch Home | Source on GitHub | Reference Documentation

Support for Spring Data

Spring Data is a collection of projects intended to make it easier to develop Spring-powered applications that use new data access technologies such as non-relational (NoSQL) databases. Based on a model of exposing Repository objects, Spring Data allows applications to access data in a simple and consistent way across many new platforms. Spring Batch 2.2.0.RELEASE provides ItemReader implementations for Neo4J and MongoDB as well as ItemWriter impelementaions for Neo4J, MongoDB and Gemfire. We also have created a RepositoryItemReader and RepositoryItemWriter…

Dear Spring Community,

I am happy to announce the second milestone release 3.3.0.M2 of the Spring Tool Suite (STS) and the Groovy/Grails Tool Suite (GGTS).

Highlights from this milestone build include:

• 4.x-based distributions now on Eclipse Kepler 4.3 (RC2)
• ready for Spring Framework 4
• new and unified "New Spring Project" wizard
• improved support for JavaConfig-driven Spring projects
• Groovy-Eclipse now has a smaller install footprint and uses less memory
• GGTS now includes Grails 2.2.2

Both tool suites ship on top of the latest Eclipse Juno SR2 release as well as on top of the latest Eclipse Kepler 4.3.0.RC2 release candidate. For optimal performance and stability we still recommend the distribution that is based on Eclipse 3.8.2.

The 3.3.0 release is scheduled for July 2013 - shortly after the Eclipse Kepler release.

To download the distributions, please go visit:

• Spring Tool Suite: http://www.springsource.org/sts
• Groovy/Grails Tool Suite: http://grails.org/products/ggts

Detailed new and noteworthy notes can be found here: STS/GGTS 3.3.0.M2 New & Noteworthy.

Enjoy!

Welcome to another installment of This Week in Spring. The SpringOne2GX super early bird registration discount expires on June 10th, 2013, so make your arrangements now to secure the discount. Also, we've got three webinars coming up this month, check out the details below. As usual, we've got a lot to cover, so let's get to it!

1. I'll be doing a webinar on building effective REST APIs with Spring on June 13th. I'll be introducing Spring's deep support for REST services, starting with Spring MVC and moving up the Richardson Maturity Model to incorporate Spring HATEOAS and, ultimately, Spring Data REST. Along the way we'll look at the REST shell, and other concerns like security through OAuth.
2. Join Jon Brisbin as he introduces Reactor in a webinar on June 18th. Reactor provides a foundational framework for applications that need high throughput when performing reasonably small chunks of stateless, asynchronous processing.
3. Join Tony Erksine from Liberty University on June 27th as he instructs us How to talk Spring and Influence People, a pragmatic lesson on soft skills and technology adoption strategies needed to help get other developers in your company excited about,a nd using, new technology -- in this case, with Spring.
4. If you're in the bay area, be sure to check out JAXConf happening right now in Santa Clara. Admission is free and there are some great speakers there. I will be speaking there tomorrow on Spring 4, and Multi Client Development with Spring, so feel free to drop by if you'd like to talk Spring, Cloud Foundry and big-data.
5. You probably saw Paul Chapman's awesome posts introducing Spring MVC's support for content negotiation last month and this month he's back with a post on content negotiation using Spring MVC views. Be sure to check both of them out, as they provide solid foundations for dealing with content negotiation in the ever increasing paradigm of REST.
6. Our friend Petri Kainulainen continues his look at Spring Data SOLR and explains how to add custom repository methods to the implementations above and beyond what Spring Data already provides out of the box. This example is in the context of Spring Data SOLR but the approach is generic and works for all the repository implementations.
7. RabbitMQ ninja Alvaro Videla has done an amazing job introducing RabbitMQ's power in the latest edition of Developer Magazine.
   
8. Every now and then I run into old but cool content, like this project demonstrating how to build a Spring MVC application with Scala. As you might imagine, there's not much difference between Scala and Java, but this is nonetheless an interesting example. Check it out.
9. I've been knee deep in REST, in preparation for my upcoming webinar, and I stumbled upon a great, albeit older, post by Apache Shiro PMC member and REST-ninja Lez Hazelwood on providing good client feedback on errors with REST in Spring MVC.
10. Spring HATEOAS lead and Spring Data ninja Oliver Gierke did an amazing talk introducing Spring HATEOAS at Oredev last year and it's available online. Definitely be sure to check it out!
11. Our pal Nicolas Fränkel is back, this time with a short rant on how to approach modularity in Spring configuration.
    
12. JavaBeat has a nice post on how to handle themes in Spring MVC.
13. The BitwiseOR blog has a nice post on how to setup a simple, working Spring MVC application.
14. Alexey Zvolinskiy put together a nice, complete-with-code, post on how to use Spring Data JPA to build an application.
15. David, from The small world for Yiyi blog, has put together a nice post on using PDF, XML and JSON from Spring MVC.
16. Our pal Johnathan Mark Smith is back, this time with another video introducing how to use Spring's Java configuration
