Empowering your apps with Spring Boot's property support

Engineering | Greg L. Turnquist | October 30, 2013 | ...

Spring Boot is continuing to gather steam. Last month I wrote Contributing to Spring Boot with a pull request. I peeled back the layers of Spring Boot to demonstrate it's incredible autoconfiguration features and CLI support.

In this post, I want to dig into Spring Boot's amazing support for properties. Properties are something that are small, not highly visible, yet can quickly strengthen your application in very practical ways. In this post, I'll walk through how I added property support to the Spring JMS support I coded in the previous blog post.

What are properties?

Properties are…

This Week in Spring - October 8th, 2013

Engineering | Josh Long | October 07, 2013 | ...

Welcome to another installment of This Week in Spring

I spent the weekend at the amazing Silicon Valley Code Camp event. It was an amazing event. People who visited the Pivotal booth got a chance to play with Spring Boot. People versed in Java, iOS, Python, .NET, Objective-C, and more all used Spring Boot to setup a RESTful service in a matter of minutes. To be honest, I found the results ("Wow! I didn't know you could do that!") both amusing and very satisfying! People are really getting into Spring Boot.

  1. Speaking of Boot, did you miss Phil Webb's Spring Boot webinar? If so, don't worry! You can watch it online!
  2. Roy Clarkson's announced the availability of Spring Mobile 1.1.0! The new release - as many of you know from having followed this roundup - features improved device detection in LiteDeviceResolver, tablet support in SitePreference and SiteSwitcher, a Java-based configuration API, and LiteDeviceDelegatingViewResolver. Nice!
  3. Martin Lippert's just announced the latest and greatest cuts of the Spring Tool Suite and Groovy/Grails Tool Suite (3.4.0) which feature - among many other things - support for following the Getting Started Guides on the home of Spring - Spring.io. These releases also see updated support for Grails 2.2.4, and tc Server 2.9.3.
  4. For more, check out the new & noteworthy. Both tool suites ship on top of the latest Eclipse Kepler SR1 release. The next version (3.5.0) is scheduled to arrive in March 2014, shortly after the Eclipse Kepler SR2 (4.3.2) release.
  5. Did you miss the amazing Platform CF conference? Don't fret, the videos of the show are trickling up online. Ashwin Kumar, a principal Software Engineer at Pivotal, did a great job introducing Pivotal HD as a Cloud Foundry Service. Pivotal HD is the world's fastest Hadoop distribution, leveraging the mature SQL query engine known as HAWQ.
  6. Not strictly Spring related, but there's a nice post on the GoPivotal blog on analyzing retail data using HAWQ and Madlib, the analytics (and machine learning!) engine originally part of Greenplum and now available to HAWK users. Nice post! This whole stack integrates nicely through Spring XD, of course, but even if it didn't, that's a really cool use case!
  7. Did you miss SpringOne2GX 2013? Check out the first night's keynote featuring Pivotal CEO Paul Maritz, Adrian Colyer, David Syer, Juergen Hoeller, Chris Beams and Edward Hieatt!
  8. Check out the replay of Param Rengaiah's webinar, Taming Coupling and Cohesive Beasts with Modularity Patterns and Spring!
  9. Are you looking for the downloadable .zip distributions for Spring? We'll make them easier to find on our new site soon, but in the meantime, simply visit the Artifactory repository and type in spring-framework in the search field. Dig a bit and you'll find it. This a more direct link.

This Week in Spring - October 1st, 2013

Engineering | Josh Long | October 02, 2013 | ...

Welcome back to another installment of This Week in Spring! There is, of course, lots to talk about so let's get to it.

If you're in the bay area, I'd like to invite you to the Silicon Valley Code Camp this weekend. I'll be giving two talks - one on building RESTful Services with Spring and the other on Improving Spring Java configuration muscle-memory with the amazing Phill Webb. Pivotal will also have a booth there, and we'd love to see you!

  1. Spring Data Arora SR3 has been released! The new release folds in Spring Data Commons 1.5.3, Spring Data JPA 1.3.5, Spring Data MongoDB 1.2.4 and Spring Data Neo4j 2.2.3. Nicely done, as usual, Oliver!

Contributing to Spring Boot with a pull request

Engineering | Greg L. Turnquist | September 20, 2013 | ...

In case you missed this year's SpringOne 2GX conference, one of the hot keynote items was the announcement of Spring Boot. Dave Syer showed how to rapidly create a Spring MVC app with code that would fit inside a single tweet. In this blog entry, I will peel back the covers of Spring Boot and show you how it works by putting together a pull request.

Autoconfiguration

Spring Boot has a powerful autoconfiguration feature. When it detects certain things on the classpath, it automatically creates beans. But one feature it doesn't yet have is support for Spring JMS. I need that feature!

This Week in Spring

Welcome back to another installment of This Week in Spring! I'm still reeling from last week. If you were there, you know what I mean, if not, then look forward to the videos coming out over the coming months. There's so much stuff to see.

For those of you who were at the show and sought me out because of This Week in Spring, it was really great to meet you all!

The world keeps on spinning of course, so let's look at some of what's happened this last week.

  1. Jennifer Hickey has announced that Spring Data Redis 1.1 has been released. The new release provides support for pipelining, data type conversion, and a modified API for adding or removing multiple List, Set, and Hash elements all in one call. Great stuff, check it out!
  2. AspectJ, Scala, Cloud Foundry, and Spring framework ninja Ramnivas Laddad has just announced the first cut of the Spring Cloud project, which in turn is a revolutionary API that takes the cloudfoundry-runtime library previously used with Cloud Foundry applications to the next level, opening the doors for support of multiple providers. Nice job, Ramnivas! And, dear community, if you want to see more, now's the time to check out the code and sound off!
  3. Over on the @GoPivotal blog, Stacey Schneider has put together a very nice post on her experiences at her first SpringOne2GX last week. Great read, and I echo her sentiments, even though this was not my first SpringOne2gx! :)
  4. Didn't get enough Data-love last week? Spring Data ninja Oliver Gierke just announced the latest cuts of two community modules: the first milestone of Spring Data Couchbase lead by Michael Nitschinger and the 1.0 GA of Spring Data Solr lead by Christoph Strobl.
  5. I put together a blog that introduces some of the things required to make the Spring Social binding that Roy Clarkson and I demonstrated last week at SpringOne2GX work with Spring Android, specifically as concerns the loading of certain classes in Spring core, Spring Security and Spring HATEOAS. Check it out!
  6. Groovy/Grails, and Spring, Tool Suite ninja Martin Lippert has just announced the latest iteration of STS and GGTS, versions 3.4.0.M1, has been released!
  7. Our pal Tobias Flohre is at it again, this time with two great SpringOne2GX wrapup posts. The first looks at some of the Spring XD, Batch and Hadoop technologies demonstrated, and the second looks at Spring Boot and the Spring IO platform.
  8. Rossen Stoyanchev, the genius behind the websockets support in Spring 4, has put together an amazing slate of demos using WebSockets and STOMP (which you can work with from RabbbitMQ!) and he showed these demos off last week at SpringOne2GX 2013 to wide acclaim. Nice job! If you missed it last week, at least check out the code, now.
  9. The Ippon.fr blog has a nice (French-language!) interview with my pal Eric Bottard, a (French-speaking) developer on Spring XD. Good read!
  10. The fine folks over at IntelliGrape have put together a nice roundup of their favorite talks from SpringOne2GX on day 2. Check it out!

The Maven Dependency Dance with Spring Android, Spring Social and Spring Security

Engineering | Josh Long | September 17, 2013 | ...

Roy Clarkson (@royclarkson) and I gave a talk at SpringOne2GX 2013 in which we talked about building REST services with an eye towards consuming those services on mobile platforms like Android and iOS. This talk demonstrates the progressive evolution of an application using Spring MVC, Spring HATEOAS, Spring Data REST, Spring Security, Spring Security OAuth, and Spring Android. The code's benefited from a lot of help from Rob Winch,

Layout of the Code

The code for the talk is on my GitHub account (github.com/joshlong/the-spring-rest-stack). Importantly, the code lives in the code directory. Beneath that there are two choices: web (where you'll find the rest, hateoas, hateoas-data, and oauth, social modules) and client (where you can load the Android module and the iOS module). The modules in the web folder in respective order, demonstrate the evolution of a simple REST service which incorporates hypermedia, Spring Data repositories and OAuth security. The social
