Welcome back to another installment of This Week in Spring! I started this week back in the lovely Sofia, Bulgaria for the Cloud Foundry Open Tour event, talking to a packed audience about building Spring applications on Cloud Foundry. Now, I'm in Antwerp, Belgium, at the Devoxx conference where I'll present on what's new in Spring 3.2, Cloud Foundry and more. If you're here, I invite you to come visit the SpringSource booth and see some of the talks on Spring that I - and others - will be giving.

1. 		Roy Clarkson has announced not one, but two releases of Spring  Mobile this week! 
   

   Spring Android 1.0.1 has been released. This release includes a change to support BlackBerry 10 mobile devices. BlackBerry 10 mobile devices are now resolved as a mobile device when using the LiteDeviceResolver. Then, he released the
   1.1.0.M1 release, which folds in the 1.0.1 support as well as tablet support in site preference handling and site switching, support for Java-based container configuration, and support for servlet based configurations.

2. Thomas Risberg has announced the GA release of Spring Data JDBC extensions with QueryDSL and Advanced Oracle support.
3. There's a lot of interesting…

Dear Spring Community,

We are happy to announce the release of Spring Mobile 1.0.1!

Spring Mobile provides extensions to Spring MVC that aid in the development of cross-platform mobile web applications.

This release includes a change to support BlackBerry 10 mobile devices. BlackBerry 10 mobile devices are now resolved as a mobile device when using the LiteDeviceResolver. See the changelog and reference manual for more information.

To retrieve the software, download the release distribution, or add the maven artifacts to your project. Sample apps are available at github.com/SpringSource/spring-mobile-samples

If you are building a mobile web app, we encourage you try out Spring Mobile 1.0.1 and collaborate with us on the next iteration of the project.

Dear Spring Community,

We are happy to announce the release of Spring Mobile 1.1.0.M1!

This release includes a number of new features, including BlackBerry 10 device detection, tablet support in site preference handling and site switching, support for Java-based container configuration, and support for servlet based configurations. See the changelog and reference manual for more information.

To retrieve the software, download the release distribution, or add the maven artifacts to your project. Sample apps are available at github.com/SpringSource/spring-mobile-samples

If you are building a mobile web app, we encourage you try out Spring Mobile 1.1.0.M1 and collaborate with us on the next iteration of the project.

[callout title=Update Dec 19, 2012] The final Spring Framework reference documentation contains guidance on migration as well as a complete section on Spring MVC Test. [/callout]

Last week Juergen Hoeller announced the release of Spring Framework 3.2 RC1 and Sam Brannen discussed exciting additions in its spring-test module such as support for WebApplicationContext's and upcoming plans for loading a hierarchy of contexts. Today I will continue this subject and describe another exciting spring-test addition. In 3.2 RC1 we've added first class support for testing Spring MVC applications both…

Dear Spring Community,

We are pleased to announce the availability of the 1.0 GA release of the Spring Data JDBC Extensions project providing Querydsl and advanced Oracle Database support!

The Spring Data JDBC Extensions project was created to provide additional support for vendor specific JDBC extensions as well as new approaches to working with JDBC like Querydsl. The bulk of the support consists of code ported from the SpringSource project "Advanced Pack for Oracle Database" that was available for support subscription customers. We are now making this code available to all Spring users and…

As Juergen Hoeller mentioned in his post announcing the release of Spring Framework 3.2 RC1, the Spring Team has introduced some exciting new features in terms of testing support. Most importantly, we've added first-class support for testing web applications. [1]

      Please note: this is a cross post from my Swiftmind company blog.

In this post we'll first take a look at some of the general new testing features in the Spring Framework, and then we'll go into detail regarding support for testing with a WebApplicationContext as well as request and session scoped beans. We'll close with a look at support for ApplicationContextInitializers and a brief discussion of the road map for testing with application context hierarchies.

Rossen Stoyanchev will later follow up with a detailed post on the new Spring MVC Test framework that provides first-class support for testing Spring MVC applications. So be sure to stay tuned for that as well, since it builds on the basic web testing support discussed later in this post.

General New Features and Updates

Build and Dependencies

The spring-test module now builds against and supports JUnit 4.10 and TestNG 6.5.2, and spring-test now depends on the junit:junit-dep Maven artifact instead of junit:junit which means that you have full control over your dependencies on Hamcrest libraries (e.g., hamcrest-core, hamcrest-all, etc.).

Generic Factory Methods

Generic factory methods are methods that implement the Factory Method Design Pattern using Java Generics. Here are some example signatures of generic factory methods:

public static <T> T mock(Class<T> clazz) { ... }

public static <T> T proxy(T obj) { ... }

The use of generic factory methods in Spring configuration is by no means specific to testing, but generic factory methods such as EasyMock.createMock(MyService.class) or Mockito.mock(MyService.class) are often used to create dynamic mocks for Spring beans in a test application context. For example, prior to Spring Framework 3.2 the following configuration could fail to autowire the OrderRepository into the OrderService. The reason is that, depending on the order in which beans are initialized in the application context, Spring would potentially infer the type of the orderRepository bean to be java.lang.Object instead of com.example.repository.OrderRepository.

<beans>

  <!-- OrderService is autowired with OrderRepository -->
  <context:component-scan base-package="com.example.service"/>

  <bean id="orderRepository" class="org.easymock.EasyMock…

Welcome back to another installment of This Week in Spring! We've got a lot to cover, so let's get to it!

1. Did you guys miss SpringOne2GX 2012? I'm not going to lie to you - you really missed out! However, don't despair! Two of my absolute favorite talks from the show are now available online - the keynotes! Both were amazing, but if you're looking for an amazing introduction to the trends underlying next generation of web applications, and a great (amazing!) tour of RabbitMQ, check out the day 2 keynote!

2. Guys, I'm so excited to tell you that SpringOne is coming to India! Register now!
3. Does your PaaS support your workloads? If you're using Cloud Foundry, then chances are good that it does!
4. Michael Isvy has put together a nice post on Spring MVC and the view layer
5. The Spring Framework TestContext framework now supports session/request scoped beans for integration testing
6. The first milestone of Spring Data SOLR has been released!
7. Jonathan Brisbin has announced the 1.2 release of the Spring REST Shell. The new release features SSL, basic auth, dotrc support, an updated Homebrew install formula, HATEOAS and hypermedia.
8. Check out Costin Leau's webinar introducing Spring Data Hadoop this Thursday!

10. Spring Data Batch and Spring Security OAuth ninja and Cloud Foundry UAA committer Dr. David Syer has written a really fantastic post on using Cloud Foundry's UAA agents OAuth2 endpoint. This has scarce little to do with Spring, except that Dr. Syer's posts are very educational and helped me tremendously in understanding the problems that Spring Security OAuth solves.

Spring Integration implements Enterprise Integration Patterrns using the Spring programming model to enable messaging in Spring-based applications. Spring Integration also provides integration with external systems using declarative adapters supporting jms, http, amqp, tcp, ftp(s), smtp, and so on. Currently, configuring message flows is primarily done via Spring XML and Spring Integration supports several namespaces to make this as succinct as possible. Earlier this year, SpringSource released a Scala DSL for Spring Integration. Now, we are pleased to announce the first milestone release…
