Spring MVC forms a solid foundation to implement REST based web-services in Java. However, in real-world projects developers still face challenges when it comes to advanced questions of REST. How to really leverage hypermedia? How to model more complex business functionality with REST. The talk introduces the Spring RESTBucks sample implementation of a hypermedia-driven REST web service and explains how it is using hypermedia elements to implement business processes and how Spring technologies (Spring Data REST, Spring Data JPA and Spring HATEOAS) help developers building the system. Learn more about REST at http://projects.spring.io/spring-framework/ (spring MVC's REST controller) http://projects.spring.io/spring-hateoas/ (Hypermedia Support)

The OAuth2 specification (wisely) leaves a lot of areas open to interpretation and implementation details, so there are a lot of opportunities to impose interpretations on the flows and the underlying data. This presentation starts with a basic guide to the main features of OAuth2 and then goes on to show, with examples, how they can be exploited to support business and application use cases. For instance, should you encode access decision data directly in the access token, or make the token completely opaque? Should you be signing requests? What naming convention should you use for OAuth2 scopes? How do you go about registering users and clients? There are some obvious patterns in existing OAuth2 implementations, and Spring Security OAuth provides plenty of hooks and extension points should you wish to copy one of those, or make your own rules. Examples will use Spring and Spring Security to show how to take advantage of the inherent flexibility, both in the spec and in the libraries.

Welcome back to another installment of This Week in Spring! Things are starting to ramp up considerably here on the Spring team. This week, on the 9th, we have the very anticipated Spring 4 release webinar Registration has been crazy! I'll be there, watching and helping to MC. I hope you'll be there too!

Also, if you're in the Bay Area, I'll be speaking at the Oakland JUG on January 22nd for a few hours in an evening we're calling Have You Seen Spring Lately?. We'll look at the epic last year's worth of awesome, including the release of Spring 4, Spring Boot and Spring XD. I hope you'll join us there, too! Bring questions!

1. On Jan 16th, 2014, our Spring Security lead Rob Winch will introduce the Spring Security 3.2 release and talk about it's support for Java Configuration, CSRF Protection, Security Related HTTP response headers, optional Spring MVC integration, and of course, Spring Framework 4.0.
2. Patrick Grimard has put together a nice post on using Spring Security 3.2.0's CSRF protection with a Backbone (or, really, any client-facing application). There is, as Spring Security Rob Winch points out, a simpler still way to achieve this.
3. Feburary is Security month! We've just released a SpringOne2GX 2013 Replay: Data Modelling and Identity Management with OAuth2, with Dr. David Syer..
4. On the REST front, also just released another SpringOne2GX 2013 Replay: Spring RESTBucks - A hypermedia-driven REST webservice, with Oliver Gierke.
5. Roy Clarkson put together a great post on how to use WebJars, which lets you manage client-side dependencies like JavaScript using traditional JVM-based build-management tools like Gradle and Maven, along with Spring Boot.
6. This post - about application instrumentation for logging, is a little old, but I thought it worth mention because it's generally pretty insightful and it demonstrates its concepts in terms of not only the canonical Spring Pet Clinic application, but also the Node.js Node Cellar, and the .NET Music Store. Not bad!
7. Our pal Petri Kainulainen is back! He's written a nice post on how to use the JOOQ typesafe query API with Spring
8. This post has so very little to do with Spring, but it does have to do with GemFire XD (our in-memory, distributed data-store that can work in-memory or with HDFS) and a bit of clever Python tinkering to access GemFire XD from Python.
9. Did you see this epic post on running a Spring Boot-powered web service on a Raspberry Pi?
10. Ned Lowe's put together a nice post on migrating from Spring MVC 2.0-style MVC applications to the annotation-centric approach available since Spring MVC 2.5.
11. Thys Michels has put together a nice post on JUnit testing Spring MVC services.
12. And thanks to the Learning Spring blog for the friendly reminder that Spring applications expose a lot of valuable logging for your exploitation if you simply modify the right configuration files.
13. Tomas Zezula put together a nice post on Spring's @Primary annotation, which lets you disambiguate the choice for which dependency to use from among many possible dependencies.

Welcome to 2014! 2013 was an exciting year for Spring, and we look forward to another great year. We have focused on client-side development in a few recent posts, including that we have published several new client-side getting started guides. In a previous post, I also reviewed how easy it is to serve static web content with Spring Boot.

In this post I will continue the discussion about client-side development with Spring Boot as we explore another built-in capability. My previous post included the following excerpt from the source code for WebMvcAutoConfiguration which illustrates how static resources are automatically added to a Spring MVC ResourceHandlerRegistry…

Happy New Year! Welcome back to this year's final installment of This Week in Spring!

We'll do some of the news, as usual, and then I'll take a look back over the last year in news surrounding Spring, of which there's been much indeed!

1. Matt Raible, who we know has also been looking at Spring Boot, just wrote up our just-released Spring 4 for InfoQ. Definitely worth a read if you have the time!

• Xavier Padró has a nice post on retrying web service operations with RequestHandlerRetryAdvice.
• There's a great discussion on Stack Overflow on Spring's CrudRepository vs. the more JPA-specific JpaRepository with an awesome answer by Spring Data lead Oliver Gierke
• Ken Blair has put together a nice introduction to doing bean mapping using the Orika bean-mapping framework alongside Spring
• Groovy ninja Guillaume LaForge has started putting together a nice roundup of all the latest happenings in the Groovy community, and I'd just like to invite readers of …

Happy holidays! Hopefully with the holiday season comes some time off, and a chance to relax and more fully catch up on fun stuff you missed during a busy year. Readers of this column will know there are many channels for developers learning about Spring, and studying the field of technologies that Spring supports. Don't forget about our SpringSource YouTube page, Twitter account, our 15-30 minute "Getting Started" guides, the blog, and of course our Facebook and Google+ pages. I personally want to go back and watch as many SpringOne2GX talks on the YouTube channel as I can.

1. Remeber JHipster? Julien Dubois's Yeoman-powered code generator for Spring applications? Well, 0.0.6 has been released and it has no required Spring XML (and Java EE's web.xml's the last one!) and provides code-generation support for services.
…

We made a few announcements recently about the Spring getting started guides, including that the catalog of guides have been migrated to Asciidoctor. We also added several new client-side guides illustrating how to connect to Spring services from a variety of client technologies.

In this post I want to highlight an interesting capability of Spring Boot; within many of the client-side guides we utilized Spring Boot to stand up a Tomcat instance and serve static content. In these guides we are demonstrating JavaScript client code, not Java or Groovy! If you are already familiar with Boot, then…

Following the recent 3.0.0.RELEASE, we are pleased to announce that the second (first public) milestone of Spring Integration 4.0 is now available.

As mentioned in the 3.0 Release Candidate Announcement the recent Spring Integration 3.0 release is fully compatible with Spring Framework 4.0, but it does not use the spring-messaging module. This allows Spring Integration 3.0 to be used with earlier versions of Spring Framework.

The 4.0 stream from which this milestone is built replaces all the core Spring Integration messaging abstractions with those in the spring-messaging module. The reason for another major release so soon after 3.0 is based on the fact that existing applications that directly use the affected SI classes in their code will need to convert to the Spring Framework abstractions. For the most part, this just means package changes in import statements, but full details are provided in the Migration Guide…
