Welcome to another installment of This Week in Spring! This week we're at OSCON in beautiful Portland, OR! It's been a crazy busy week, and only figures to be busier! It's been nice visiting with colleagues and community members alike. The booth on the expo floor has been flooded with users. I love this show. :)

1. First, the big news: the Spring framework 4.1 release candidate is now available! The new release features updated JSR-107 support, JMS 2.0 and annotation-centric JMS configuration, a SpEL compiler, and so much more.

• Spring XD co-lead Dr. Mark Pollack has just announced that Spring XD RC1 is now available. Installation is dead-simple. There are numerous new features, and this train's moving fast so check it out, download the bits, kick the tires, etc.
• Spring Data ninja Christoph Strobl put together a nice blog post introducing Spring Data MongoDB's full-text search
• The A Piece of My Code blog looks at how to use Spring's integration testing with mock services.
• Tousif Khan has put together a nice post on Spring's view controllers
• The Tech Zoo blog wrote up how to use Spring's Apache Tiles support
• The softwarecave blog introduces how to handle …

MongoDB officially has offered full text search capabilities since its 2.6 release. The feature ranks among the Top 5 most voted features for the server component and ships in its current version with numerous stemmers and parsers, phrase matching, negation and per field weights. So it's about time to give it a little love and share what's cooking in Spring Data's kitchen to support that feature.

For text indexing and searching MongoDB defaults the language to English, normalizing the text by tokenizing, removing common stop words and reducing words to their base. There's support for several…

Spring Data JPA allows manually defining the query to be executed by a repository method using the @Query annotation. Unfortunately parameter binding in JPQL is quite limited only allowing you to set a value and providing some type conversion. The latest Spring Data JPA M1 release of the Evans release train eases this pain by adding support for using SpEL expressions to use dynamically bound parameters within statements in @Query annotations which provides additional flexibility when defining queries manually. In this blog post, I am going to introduce you to the capabilities of this feature.

Welcome to another installment of This Week in Spring! It's been a crazy week and next week figures to be even crazier! Some of us on the Spring team - including Spring Boot co-lead Phill Webb, Spring Batch lead Michael Minella and myself, will be at OSCON next week, so if you're in the area and at the show come say hi! We'll be at the booth at various hours, too.

1. Spring Batch lead Michael Minella has just announced Spring Batch 3.0.1, and a new Spring Batch extensions repository which itself houses new integrations with Spring Batch. The first contribution is an ItemReader and ItemWriter for Elasticsearch. Nice!
2. Spring Data ninja Thomas Darimont has just announced support for SpEL in Spring Data JPA @Query annotations
3. Spring and Groovy Tool Suite lead Martin Lippert has just announced Spring Tool Suite 3.6.0 and Groovy Tool Suite 3.6.0, based on Eclipse Luna 4.4, with support for Groovy 2.3, Grails 2.4, tc Server 2.9.6, and other minor improvements and bugfixes.
4. Spring Data ninja Christoph Strobl has just announced Spring Data Evans m1, in which many new revisions are included.
5. Speaking of the first milestone of Spring Data Evans, Spring Data REST ninja Greg Turnquist has just announced that Spring Data Evans M1 milestone comes with ALPS metadata support. FTA: ALPS provides a way to interrogate a RESTful service to find out about the data it serves. Let's look at a quick example. If you clone the TODO repo and run mvn spring-boot:run, you can surf it's values pretty easily. So.. check it out! I know many have been asking about simialar support.
6. Check out this upcoming webinar by Michael Plod on why he recommends Spring - learn the technology (and a bit of the business) case! Michael is a great speaker and frequently appears at conferences. Register now for the event on July 22nd.
7. On July 29th, Russ Danner from Crafter software will tell us about Conquering Content-enabled Web and Mobile Applications with Spring and Groovy.
8. Andreas Eisele has put together a very nice introduction to the machinery behind using @Transactional in your Spring-managed unit-tests, with analysis of common scenarios, code, and more. Vert cool discussion, and a thoughtful post.
9. The Cegega blog has a very cool look at handling exceptions using Spring Batch's RetryTemplate.
10. This subject's near and dear to my hear this week, so I just wanted to share this oldie-but-a-goodie: how to use Atomikos with Spring's JTA support
11. You are, of course, checking out Groovy-language lead Guillaume LaForge's This Week in Groovy, aren't you? :-)

With the recent release of Spring Data's Evans M1 milestone, Spring Data REST now comes with support for ALPS metadata to describe the semantics of the resources exported.

ALPS is a data format for defining simple descriptions of application-level semantics, similar in complexity to HTML micro-formats. It also supports adding its metadata to existing media types. As of version 2.2 M1, Spring Data REST exposes JSON based ALPS resources that can help us navigate its resources. Let's see how!

We can start with a quick example. If you clone the TODO repo and run mvn spring-boot:run, you can…

I'm pleased to announce the release of Spring Session 1.0.0.M1.

Feedback Please

If you have feedback, I encourage you to reach out via github issues, via the comments section, or ping me on twitter @rob…

Welcome to another installment of This Week in Spring! I hope our American readers had a pleasant 4th of July, and I hope everybody else had a pleasant Friday!

There is, as usual, a lot to discuss this week so let's get to it!

1. Sleepless Spring Security lead Rob Winch has just announced the first milestone of Spring Session. Spring Session makes it easy to access a session from any environment (i.e. web, messaging infrastructure, etc), support for clustering in a vendor neutral way, plug in strategies for determining the session ID, and easily keep the HttpSession alive when a WebSocket is active. This is really cool! And, in fact, it might solve an issue I faced just last week where I wanted to access the HTTP session from a Web Socket handler!
2. Andy Wilkinson has just announced Spring Boot 1.1.4 release. The new release includes many bug-fixes and small new features, including support for the first stable preview release of Tomcat 8.
3. Andy also just announced the first maintenance release to Spring IO which updates versions across the platform to include Spring AMQP 1.3.5, Spring Boot 1.1.4, Spring Batch 3.0.1, Spring for Apache Hadoop 2.0.1, and Spring Framework 4.0.6. Nice job, Andy!
4. Thomas Risberg has just announced Spring for Apache Hadoop 2.0.1 which revs the dependency versions, including Hadoop 2.4.1, Spring framework 4.0.6.RELEASE, Spring Batch to 3.0.1.RELEASE, Spring Boot to 1.1.4.RELEASE.
5. Stéphane Nicoll has just announced that Spring framework 4.0.6 is now available. This release includes about 50 bugfixes.
6. Spring Social lead Craig Walls has just announced that Spring Social Facebook 2.0.0.M1 is now available. This release supports the new Facebook v2.0.0 Graph API, which introduces some breaking, obligatory, changes (thanks, Facebook!).
7. Groovy project lead Guillaume LaForge has announced the beta of the new Groovy website and is soliciting feedback from the community at large.
8. From the trenches: Join Casey Doolittle and Phil Dutson on July 15th for a webinar about a crazy project, and how they had to Build a Shopping Cart in 24 Hours using Spring.
9. Check out this upcoming webinar by Michael Plod on why he recommends Spring - learn the technology (and a bit of the business) case! Michael is a great speaker and frequently appears at conferences. Register now for the event on July 22nd.
10. On July 29th, Russ Danner from Crafter software will tell us about Conquering Content-enabled Web and Mobile Applications with Spring and Groovy.
11. Last year, Spring tool ninjas Andy Clement and Martin Lippert did a great talk at SpringOne2GX 2013 introducing the latest and greatest tooling.
12. Last year at SpringOne2GX 2013, Julien Dubois (you might recognise him from JHipster..) did a great talk looking at how to run and performance tune the classic Spring petclinic application.
13. Dr. Dobb's had a nice post looking at the new Spring IO release.
14. InfoQ's Matt Raible also put together a nice look at Spring IO. Check it out!
15. The Literate Java blog has an interesting post on implicit (component-scan-centric) vs. explicit configuration (using XML) in Spring. I'd argue that Java configuration should really be considered as it offers the best of both explicit XML configuration (centralized, easy-to-reason about configuration) and implicit, but type-safe, Java annotation-and-component-scann-centric configuration. Either way, interesting post!
16. Spring Boot is now in Thoughtwork's technology radar under assess.
17. The Codeleak.pl site has a nice look at one of the smaller, but super powerful, features in Spring 4 - CGLIB proxies no longer require a default constructor!
18. I've enjoyed this series of tutorials on using Spring and Angular.js. You might as well. Nice job, Christopher Henkel!
19. The Apprenticeship Notes blog has a nice series of tutorials on how to use Spring MVC, Thymeleaf, and Bootstrap together.
20. The Autoletics blog has a nice, numbers-filled, look at their experience profiling the Reactor project. Interesting stuff! Some of the points are interesting, too. As readers of this roundup know, Reactor is a highly concurrent event-driven IO-ready platform. And, it's ridiculously fast.
21. I wanted to give a hat tip to Paul Snively, who has been using the 1-2 punch combo of the Spring (and Scala) and a third-party integration of Spring MVC for Alfresco to build Alfresco-powered solutions. Nice!
22. Whether you like the new Groovy website or not (although, why wouldn't you?), you'll love the new Groovy 2.3.4 release which just dropped today and includes improvements on static compilation and AST transformations.
23. HornetQ project-lead Clebert Suconic is inviting community feedback about a proposed contribution of HornetQ to the Apache ActiveMQ project. We know that developers in our community know and use both, so perhaps now's a prudent time to feedback if this proposed merger affects you! I personally like the idea. ActiveMQ.next (long codenamed "Apollo") seems like it could use the hug that a HornetQ-contribution could give it. And, of course, Spring Boot supports both ActiveMQ and HornetQ now, so either way, you're set!

Welcome to another installment of This Week in Spring! It's already July, and Summer is here! Can you believe it? Time sure flies. We've got a lot to cover this week, as usual, so let's get to it.

1. Last week, we announced the Spring IO platform. I won the lottery on this one, and they let me write the blog, but this effort reflects more than a year of internal discussion, planning, hard work, cooperation and coordination between all the Spring projects. I did my level-headed best to introduce the Spring IO platform in this blog. You should read it. If it doesn't sound awesome and very, very useful, than I've simply done a poor job explaining it! :D Don't hesitate to reach out. The Spring IO platform is a radically simpler way of dealing with dependencies across all the Spring…

We're pleased to announce the release of Spring IO 1.0!

Spring IO is first and foremost a logical description of what many of users will already know and use as a single, cohesive, harmonized platform, centered around Spring.

Big Things Come in Small (Java) Packages

The Spring IO platform includes Foundation Layer modules and Execution Layer domain-specific runtimes (DSRs). The Foundation Layer represents the core Spring modules and associated third-party dependencies that have been harmonized to ensure a smooth development experience. The DSRs provided by the Spring IO Execution Layer…
