Welcome back to another installation of This Week in Spring! I'm hurriedly preparing for a busy few weeks. I'll be giving a tech talk at our office (875 Howard St, San Francisco, CA) on the 18th (and you're more than welcome! Just turn up around 12:30 PST on Tuesday the 18th and join us as we talk Boot, baby!), some training on the 19th, then I'll be in Atlanta for the epic DevNexus show and then, the very next day, off to Montreal, Canada for the ConFoo conference. I hope to see you here, at the GoPivotal offices for the tech talk, or in Atlanta, or in Montreal!

This week we've got lots of…

As we're approaching the home stretch of the Spring Data release train currently in development, I think it's time to give you a brief overview of some of the new features we're going to introduce with this release.

In case you're not aware yet, the release train is a coordinated release of multiple Spring Data modules to make sure they work seamlessly out of the box. The current one is named after the inventor of the relational model Edgar F. Codd.

Spring Data Commons

As the Spring Data Commons module creates the foundation for all of the other modules contained in the release train, new…

Now that Thomas has just released a fifth milestone for Spring for Apache Hadoop, I'd like to use this opportunity to talk about recent development in its new feature, Spring YARN.

One strength in our Spring IO Platform is interoperability of its technologies. Great example of this is how Spring Boot and Spring YARN are able work together to create a better model for Hadoop YARN application development. In this blog post I'd like to show an example of a new Spring Yarn Application model which is heavily based on Spring Boot.

This release contains a small number of important fixes for the recent 3.0.0 release. 3.0 users are encouraged to upgrade to this release as soon as possible. Please see the 3.0.1 release notes and project page for more information.

Welcome back to another installment of This Week in Spring! There's a lot to cover so let's get to it.

1. Spring Integration 3.0.1 maintenance release is now available, with lots of good bug fixes, and we encourage 3.0.0 users to upgrade now. Check out Gary Russell's blog about what's new in 3.0.0 if you haven't seen it yet, lots of new features.
2. Spring Data's first release candidate of their "Codd" release train is now available!
3. Join Spring Data project leads Oliver Geirke and Thomas Darimont on Feb 18th as they school us on Spring Data Repositories - Best Practices.
4. On Feb 11th, don't miss an Intro to Apache Tomcat 8 Webinar with Apache committer Stuart Williams and Daniel Mikusa
5. In other Apache Tomcat news, the maintenance release for Apache Tomcat 6.0.39 is now available. Head over to the TomcatExpert blog to check out the details.
6. Zoltan's blog has a very nice post on building and deploying a Spring Boot application to Heroku! Check it out!
7. Spring Batch lead Michael Minella gave a nice talk on Spring Batch and the Batch JSR, JSR 352 from SpringOne2GX, replay now available!
8. Another SpringOne2GX replay this week, a fantastic talk from E*Trade architect Durai Arasan, on Real life use of Spring Integration with RabbitMQ at E*Trade. One of the best talks of SpringOne2GX 2013!
9. spring.io lead and Spring ninja Chris Beams has put together a great post on what open-source means for all of us here at Pivotal. Check it out, and spread the word!
10. Our pals at Neo4J got some great TechCrunch coverage about how Neo Technologies is changing the world of Graph databases!
11. Blogger Brian put together a neat look at one way to handle common web development tasks like resource optimization (JavaScript transpilation, JavaScript and CSS minification, etc. ) with WRO4J and Spring. Check it out!
12. Spring lead Juergen Hoeller put up a nice post on how to migrate from Spring 3.2 to Spring 4.0.(1).
13. The Cygnet Infotech blog put together a neat infographic about Grails titled 6 Reasons Why Grails is an Awesome Java Web Framework. I have no idea what the infographic means by "Java" web framework, but it's certainly an epic JVM web framework, and the rest of it is as true as can be!
14. The Programming Free blog has a post on building RESTful services with Spring MVC 4.0. This post is technically correct, but could stand to be even simpler! (See below)
15. Fred George, who I had the pleasure of meeting last year (when I spoke at Oredev) through our mutual pal Chris Richardson, did a great talk in 2012 about building micro services which you can watch here. This video has nothing, specifically, to do with Spring. It instead focuses on building loosely coupled, discrete, micro services that - taken together - describe a system. Why do I mention this? Because Spring Boot makes it dead simple to build such services! Check out the Spring Initializr, select the functionality you need (perhaps web and JPA), open up Application.java, and then add a REST endpoint! Here's an example of a complete, working REST service powered by Spring Boot. The only thing I omit is the Maven (or Gradle) build file.

Welcome to another installment of This Week in Spring!

A quick reminder: I'll be co-presenting a webinar introducing how to use Spring and Vaadin, the rich internet application framework, together with some folks from Vaadin. We'll present some common integration options and a few not so common ones, too! Stay tuned, and I hope to see you there!

Also, I'm starting to flesh out my speaking agenda for the next few months. So far, I know I'll be at the Great Indian Developer Summit in Bangalore, India from April 22-25, and at be at Geecon in Krakow, Poland from 14 May - 16 May. If you're in either of those regions, I'd love to see you. If you host a JUG or a UG or have a large development team and audience, I'd love to have a chance to talk with you and your group, as well. Ping me.

As usual, we've got a lot to get through, so let's get started!

1. Spring lead Juergen Hoeller has announced today a double feature release: both Spring 4.0.1 and Spring 3.2.7 have been released! Check it out.
2. Phil Webb has just announced the first release candidate for Spring Boot 1.0.0!
3. Join Apache Committer Stuart Williams and Daniel Mikusa for Introduction to Apache Tomcat 8 - Feb 8th, 2014. Reserve your seat now as this is likely to be another popular topic.
4. Webinar Feb 18th! Don't miss Oliver Gierke and Thomas Darimont as they tell us about Best Practices with Spring Data Repositories.
5. Did you miss Spring lead Juergen Hoeller's epic webinar introducing Spring 4 (which he gave twice, once for EMEA and once for NorAm timezones?) Did you also miss the two encore performances he gave a week later because the first webinar overwhelmed the web conference and left thousands of participants unable to access it? Then have no fear, you can now watch it online!
6. Along those lines, Greg Turnquist just announced that all the guides on spring.io have been upgraded to the recently released Spring Boot 1.0.0.RC1!
7. Nice! Spring MVC ninja Rossen Stoyanchev just announced an updated cut of Spring Web Flow, 2.3.3. It supports Spring 4 and JSF 2.2.
8. Over on the All and Sundry blog, Biju Kunjummen has put together a nice post introducing how to use Spring's `` - an implementation of the super type token - to correctly marshal REST API responses back and forth over the wire using generic types that would otherwise lose their generic component at runtime due to erasure. He uses the example code from the Spring REST Stack, which I developed for a talk with a lot of help from fellow Spring team members Rob Winch, Roy Clarkson, Craig Walls, Rossen Stoyanchev, Arjen Poutsma, etc.
9. Last November, I gave a talk, Have You Seen Spring Lately?. I had some trouble converting the talk from Keynote '09 to Keynote 7, and finally managed to get all that squared away. I've just uploaded the full deck (complete with extra content that some versions of this talk didn't include for want of time). I uploaded the deck on Sunday. You can find a link to the video there, as well. Enjoy!
10. Readers of this column know that I love me some good package management, and OS X's Homebrew ain't half bad. Did you know that you can install Pivotal GemFire and tcServer using Homebrew? Once you've installed the pivotal tap (brew tap pivotal/tap), simply issue brew install tcserver gemfire. Easy as that!
11. There's a deck for a talk on Spring for Apache Hadoop by Kailash Kutti.
12. Blogger Sudhir Dharmadhikari really seems to like Spring Data, and even proposes a very flattering rename for the project. To learn about why, check out his blog.
13. Spring Data ninja Thomas Darimont has just announced that Spring Data Redis 1.1.1 is now available.
14. Greg Turnquist has penned a very nice blog post explaining how you, too, can contribute to the Getting Started guides.
15. Meanwhile, over on the Pivotal blog, there's a nice post on how to use window functions in (SQL-based) data analytics. Ok, Ok, I know it has nothing to do with Spring, but it's just so darned useful. Besides, building smarter, data-centric applications will help you build smarter Spring applications!
16. Pivotal Labs Canada engineering head Farhan Thawar has a nice post on the top 5 myths of mobile application development, which line up with what we've been talking about with our mobile technologies here on the Spring team at Pivotal. Check it out, then take a look at our getting started guides to learn how Spring can help you improve your mobile offerings!
17. JHipster 0.8.0 is now out! The new release builds heavily on Spring Boot, and packs quite a whallop! Check it out!
18. Hey, have you tried out the Getting Started guides, by the way? They're dead simple! My pal and colleague Pieter Humphrey sat down and narrated his run through of some of the guides. Check it out! These two videos demonstrate useful, working code, all in about 6 minutes each!
19. BTW, I wanted to make sure people saw some of the great data- and Spring- centric posts on the GoPivotal blog from the last year. Here is one, _Adding Years to Your RDBMS by Scaling with Spring and NoSQL, another on How to Run Multiple Big Data Applications at Once with GemFire, and yet another on How to Migrate Spring applications to real time Data Grids.
20. Speaking of Gemfire, there was just recently a very nice post on how the Chinese railroad system is using GemFire to beef up its capacity in advance of the January 31st Chinese new year (or "Spring festival"). If you're reading this from China, happy new year - year of the horse - to you! You might also check out this post I put together last year on Spring at China Scale.
21. Check out this authorative guide on how Thymeleaf supports various templating styles. Templating and design can be a very important part of a site's utility, as this article - Why Simple WebSites are Scientifically Superior - explains!
22. Spring Data lead Oliver Gierke has a very nice couple of posts on Stack Overflow. The first explains how to correctly use the PagedResourceAssembler with Spring Data, and the second answers the question, are you supposed to have one repository per table in JPA?
23. There's a very good - both philosophically and technically deep - look at how to prevent unbounded queues with RabbitMQ.

Greetings Spring community!

We keep receiving feedback that Spring's Getting Started Guides are smash hit.

So far, we've migrated these guides to Asciidoctor. We have also grown our guides to include client-oriented ones. More are coming!

The final link in the chain of making these guides work in the long term are the navigational links in the sidebar of each guide. We are now using metadata to tag and link various guides together while also connecting them to relevant projects.

For example, if you visit Consuming a RESTful Web Service with AngularJS, you will see a sidebar that contains:

• shortcuts to the top-level sections of that guide
• two tags: rest and JavaScript, links that let you search for other guides containing the same tags
• a link to the Spring Framework project, given this guide is focused on combining Spring MVC with AngularJS
• links to understanding REST and understanding JSON
