Welcome back to another installment of This Week in Spring. As usual, we've got a lot to look at this week so let's get to it..

1. The video from Chris Beams's recent webinar on the various styles of dependency injection that Spring supports is up. Chris is a core Spring framework engineer (and all around good guy). This video is definitely worth a watch especially if you still think Spring configurations requires XML.

This video provides a tour of modern dependency injection and Spring container configuration styles, including those available in the Spring 3.1 release. Spring expert and long time committer, Chris Beams, shows by example the use of Java @Configuration classes, Annotated POJOs, and XML to wire up your application. The presentation covers not just how to configure the container to use these options, but will also discuss why you would choose one method over another, as well as how they can be mixed and matched.

Be sure to thumbs up the presentation if you find it useful and subscribe to the SpringSourceDev channel to see other recordings and screencasts.

Dear Spring Community,

We are pleased to announce the general availability of Spring for Android 1.0!

Spring for Android supports usage of the Spring Framework in a Android environment.

This GA release includes minor fixes and improvements since the RC1 release. See the changelog and reference manual for more information.

A significant change in this release is that the default RestTemplate constructor no longer includes any message body converters. However, an alternate constructor allows you to include a standard set of message converters, similar to previous releases. See the API Javadoc and Reference Manual for more details on this change.

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-android-samples

We want to thank the community for their contributions to this GA release, and we look forward to working with them on future releases. If you are building a native Android app, we encourage you to try out Spring for Android 1.0 and collaborate with us on the next iteration of the project.

The first milestone release toward Spring 3.2 is now available from the SpringSource repository at http://repo.springsource.org. See here for a quick tutorial on resolving these artifacts via Maven.

This release includes:

• initial support for asynchronous @Controller methods
• early support for JCache-based cache providers
• significant performance improvements in autowiring of non-singleton beans
• initial delay support for @Scheduled and <task:scheduled>
• ability to choose between multiple executuors with @Async
• enhanced bean profile selection using the not (!) operator
• 48 bugs fixed, 8 new features and 36 improvements implemented

This is also the first release since our move to GitHub and using our new Gradle build. A special thanks to the authors of the many pull requests submitted and merged during 3.2 M1! Keep them coming!

   When I asked for any items for consideration into this roundup on my Twitter account, one user immediately shot back: "With the Spring 3.2 news, how about a poll on whether the community wants 3.2 M1 to be followed by RC1. It's too good to wait." I agree, this release is…

The Spring Roo team is pleased to announce the availability 1.2.2.RELEASE.  This is the second maintenance release for 1.2 and includes fixes for a number of issues and includes support for Spring Framework 3.1.1 and JDK 7.  Roo 1.2.2 also includes the excellent new "tailor" feature provided by our new partner, Accenture.

I hope you enjoy this new release!

Dear Spring Community,

We're pleased to announce the update release 2.9.2 of the SpringSource Tool Suite (STS).

This update release got updated to support and ship the just released vFabric tc Server 2.7 and includes a few bug fixes. More details on new features and bug fixes can be found in the New and Noteworthy document. Detailed installation instructions are also available. As always downloads are available from the STS download page.

Enjoy!

In the Spring framework, many technical features rely on proxy usage. We are going to go in depth on this topic using three examples: Transactions, Caching and Java Configuration.

All the code samples shown in this blog entry are available on my github account.

Transactions

First step: no transaction

@Service
public class AccountServiceImpl  implements AccountService {
 //…

//Not specifying a transaction policy here!
 public void create(Account account) {
 entityManager.persist(account);
 }
}

Since the method “create” is not transactional, it will most likely throw an exception (because this Account object should not…
