As we have just released the first milestone of the Spring Data JPA project I’d like to give you a quick introduction into its features. As you probably know, the Spring framework provides support to build a JPA based data access layer. So what does Spring Data JPA add to this base support? To answer that question I'd like to start with the data access components for a sample domain implemented using plain JPA + Spring and point out areas that leave room for improvement. After we've done that I will refactor the implementations to use the Spring Data JPA features to address these problem…

Dear Spring Community,

I'm pleased to announce that the 1.5.0.M2 milestone release of Spring BlazeDS Integration, the open source solution for building Spring-powered RIAs with Adobe Flex, is now available.

Download | Reference Documentation | JavaDocs | Changelog

Highlights of the significant new features and enhancements in this release include:

• Support for reading and writing AMF content with RESTful Spring MVC @Controllers. This serves as a nice alternative to the direct RPC approach of the Remoting Service, reducing duplication of effort in applications that need to support multiple client types. (See the updated Test Drive for usage examples.)
  
  
• A major refactoring of the Spring Security 3 support, resulting in easier integration of Flex apps with various Spring Security features such as Remember Me, Session Fixation Protection, and Concurrent Session Control.
  
  
• Further evolution of the Hibernate serialization support introduced in 1.5.0.M1, including the option to use direct field mapping instead of property-based mapping.
  
  
• Easier customization and namespace-supported configuration of framework-provided services such as the LoginCommand and MessageInterceptors.
  
  
• Upgraded compatibility with Spring Integration 2.0.x
  
  
• A complete revision of the Maven-based Test Drive samples, including an update across the board to use Flex 4, and a brand new sample to demonstrate the RESTful programming model.

One additional item to note is that the Flex Addon for Spring Roo is no longer part of the project distribution. Instead, version 1.0.0.M2 of the Flex Addon will be released separately in the coming weeks and will be available to Spring Roo 1.1.1 users through Roo's Addon Discovery mechanism. If you'd like to try out the nightly builds of the Flex Addon (which are necessary for compatibility with Roo 1.1 and above), I encourage you to reach out to the community for guidance.

As always, I encourage anyone interested to get involved by trying out the release and giving us feedback in the community forum and Jira, as we are fast approaching 1.5.0.RC1. We continually get great feedback from people having success with Spring BlazeDS Integration in their projects, and we look forward to hearing more about your experiences.

In Spring Android and Maven (Part 1), I described how to build an Android application from the command-line using Maven. In this post, I will show you how to build an Android application with Maven dependency management from the Eclipse IDE. The application will also showcase the latest features in Spring Android 1.0.0.M2, which was released this week.

Overview

The Maven Android Plugin lets you build your Android applications with Maven and benefit from dependency management. Google's Android Development Tools (ADT) plugin allows you to develop and build Android applications within the Eclipse IDE. To get Maven dependency management within Eclipse, the Maven Integration for Android Development Tools plugin is required, which integrates m2eclipse, the ADT Plugin, and the Maven Android Plugin…

Dear Spring Community,

We are pleased to announce that the second milestone release of the Spring Android project is now available!

Spring Android supports usage of the Spring Framework in a Android environment. The 1.0.0.M2 release focuses on extending the use of RestTemplate in native Android applications:

• We now use the HttpComponents HttpClient 4 by default for all REST calls, which is a native HTTP client on the Android platform. This replaces the use of the Commons HttpClient 3 from the first milestone.
• We have added Object-to-XML marshaling support through the use of the Simple XML serialization library. Simple has a small footprint and is compatible with Android.
• RSS and Atom Feeds are now supported through the Android Rome Feed Reader. Android Rome is a port of the popular Rome library that is compatible with Android.
• Integration with the Jackson JSON Processor continues to provide first-class Object-to-JSON marshaling support.

Spring Android is available for download. If you are utilizing Maven with your Android project, simply add the following dependency:

<dependency>
    <groupId>org.springframework.android</groupId>
    <artifactId>spring-android-rest-template</artifactId>
    <version>1.0.0.M2</version>
</dependency>

<repository>
    <id>org.springframework.maven.milestone</id>
    <name>Spring Maven Milestone Repository</name>
    <url>http://maven.springframework.org/milestone</url>
</repository>

In addition to the reference guide, Roy Clarkson has authored two blog posts to help you get started developing Android applications:

• Spring Android and Maven (Part 1)
• Spring Android and Maven (Part 2)

A sample app with a README is available at github.com/SpringSource/spring-android-samples: git clone git://github.com/SpringSource/spring-android-samples.git

Work continues on the next Spring Android milestone, where we will we be integrating OAuth support for Android applications. If you're building native Android applications, we invite you to collaborate with us on the Spring Android project.

This has been another exciting week in the Spring community. The community seems abuzz about the new Tomcat release, mobile clients, Spring Data and big data (e.g., Spring Gemfire, Redis, and of course the Spring Data projects.)

A reminder: Juergen Hoeller - lead of the core Spring framework and contributor to all of the sister Spring projects, in some fashion or another - is giving two identical webinars - one for North America and one for Europe - on the new features in Spring 3.1 in two days (February 10th)! Be sure to register for this free webinar on the next iteration of the most widely used Java framework!

This is turning out to be a record event, with incredible advance registration numbers. While there are no Spring 3.1 binaries (yet; stay tuned!), the code for the Spring project is always at your disposal, so - if you're as excited about all the new features as I am - you'll see this webinar and start playing with it long before it's…

Dear Spring Community,

We are pleased to announce that the third milestone release of the Spring Mobile project is now available!

Spring Mobile provides extensions to Spring MVC that aid in the development of cross-platform mobile web applications. The 1.0.0.M3 release ships a general facility for user site preference management that can be used independently or in conjunction with the mobile site switcher. See the changelog and reference manual for all the info.

Download the release distribution or pull the artifacts from Maven using the following:

    <repository>
        <id>org.springframework.maven.milestone</id>
        <name>Spring Maven Milestone Repository</name>
        <url>http://maven.springframework.org/milestone</url>
    </repository>
&lt;dependency&gt;
    &lt;groupId&gt;org.springframework.mobile&lt;/groupId&gt;
    &lt;artifactId&gt;spring-mobile-device&lt;/artifactId&gt;
    &lt;version&gt;1.0.0.M3&lt;/version&gt;
&lt;/dependency&gt;

Get sample apps over at github.com/SpringSource/spring-mobile-samples | git clone git://github.com/SpringSource/spring-mobile-samples.git

This release marks our third iteration with early adopters in the community using Spring Mobile in their own applications. If you are building a mobile web app, we encourage you try out 1.0.0.M3 and collaborate with us on the next iteration of the project.
