I'd like to think I'm pretty comfortable with Java and generics but I recently came across this bit of Java code and it stopped me in my tracks :

public abstract class AnnotationBasedPersistentProperty<P extends PersistentProperty<P>> extends AbstractPersistentProperty<P> {..}

This class is internal to the Spring Data framework's Repository Support which removes the need to write boilerplate code when implementing a data access layer and also provides a common programming model for mapping domain objects and managing data access to any type of persistent store.  Spring Data's  current repository implementations include relational databases (JPA), Gemfire,MongoDB, Neo4.

Fortunately, if you use Spring Data in your Java…

Welcome to another installation of This Week in Spring!

This week I'm in Bangalore, India with other members of the SpringSource and Cloud Foundry teams talking to major system integrators about Spring and Cloud Foundry. The uptake's amazing, and the feedback is even better.

In related news, the Cloud Foundry Open Tour is coming to India next month! If you want to hear thought leaders and experts and learn about cloud computing, platform-as-a-service, architecture and Spring, then be sure to register now for either the Bangalore or Pune events. I look forward to seeing you there!

1. Jonathan Brisbin has announced the latest release of Spring Data Rest, version 1.0.0.RC2, which features JSONPE support, and better integration with Spring MVC applications, as well as even more configuration hooks so you can exert even more control over the behavior of the framework.
2. Dr. David Syer has announced the 1.0.0.RC1 release of Spring Security OAuth. Spring Security OAuth is a module that works with Spring Security and lets you expose OAuth-secured RESTful resources.

   The new release features lots of new extension points in the Authorization Server features, a Whitelabel UI for better out-of-box experience, and improved support for expressions in security filters. Check it out!

I'm pleased to announce the release of Spring Data REST 1.0.0.RC2! Beyond a number of bug fixes, this release adds support for JSONPE (JSONP with error handling), the ability to turn off CRUD methods with the @RestResource annotation, and is now built and tested against the Servlet 3.0 API (though it is not yet 3.0 specific, so will still work fine in Servlet 2.5 containers).

New functionality includes:

• JSONPE - Simply add a URL parameter to have the results wrapped in a call to the Javascript function you specify. Also handles server errors by translating an error to HTTP 200 and passing the original status code as the first parameter of your error handler.
• Turn off CRUD methods - The exporter now respects @RestResource annotations on CRUD methods. Just override the method from CrudRepository you want to turn off and annotate it with @RestResource(exported = false).
• Better integration with existing Spring MVC applications - Simplified the internal Spring MVC configuration to make it even easier to integrate with your existing Spring MVC application. Simply including the RepositoryRestMvcConfiguration bean into your own configuration should Just Work.

New or updated documentation includes:

• JSONP Support
• Configuring the REST URL path
• Adding Spring Data REST to an existing Spring MVC Application

I'd like to announce the availablity of new milestone and bugfix releases of Spring Data Commons (1.3.2.RELEASE, 1.4.0.M1), JPA (1.1.1.RELEASE, 1.2.0.M1) and MongoDB (1.0.3.RELEASE, 1.1.0.M2). The releases mark the very first step to a common release train that will reach the next major release mid August and include Spring Data Commons, JPA, MongoDB, Neo4J and Gemfire. The release train is an effort to simultaneously release all store modules that support the repository abstraction and thus have a common set of functionality to provide. Beyond that this will make sure the released stores interoperate with each other seamlessly.

This first milestone release includes support for JavaConfig based repository configuration by introducing @EnableJpaRepositories, @EnableMongoRepository etc. Beyond that we of course have a ton of bug fixes and improvements. For details follow the links below.

We'll have release candidates for the next major versions out there in early August, followed by the GA versions briefly after that. For more detailled information on the release train please have a look at the wiki page in Spring Data Commons.

Welcome to another installment of This Week in Spring! This week, the SpringSource and Cloud Foundry teams are OSCON talking about open source enterprise and cloud computing with anybody and everybody. If you're in the region, be sure to check out the SpringSource and Cloud Foundry booth in the exhibition hall!

1. The Spring Data team is working on a book with O'Reilly on Spring Data. If you want to preview and feedback, now's your chance!
2. Are you using Spring Data Commons support for repositories? How would you feel about support for Java-centric configuration? Check out the new support for Java-configuration in Spring Data!

Dear Spring Community,

I am pleased to announce the first milestone release of Spring Shell project! Spring Shell is an interactive shell that can be easily extended with commands using a Spring based programming model, extracted from the Spring Roo project.

We look forward to your feedback on the forum or in the issue tracker.

This video discusses the options for managing and monitoring applications that use Spring Integration. Topics covered include:

• using the Spring Integration plugin for Spring Insight to get a real-time view of your applications and its performance
• using the Integration MBean Exporter and the MBeans it registers for analyzing messaging endpoints and channels
• exporting the Integration MBean Exporter itself as an MBean, to gain access to its attributes and operations
• using the <control-bus /> to start and stop endpoints
• enabling and using Message History
• previewing the orderly shutdown mechanisms being built into Spring Integration 2.2

Welcome back to another installment of This Week in Spring. This week, I'm at JAX in San Francisco. We're having a good time, and happily answering questions from community members. As usual, though, we've got a lot to cover, so let's get on with the show.
