Introduction

Among those are a number of things which simplify the complicated and tedious problems often associated with data binding. In general, data binding is made very simple by Grails as it offers several techniques for binding maps of data to graphs of objects.

It is important that application developers understand the implications of each of those techniques in order to decide which is most appropriate and most secure for any given use case.

Web Application Data Binding Overview

Consider a domain class which looks something like this:

Code Listing 1

class Employee {
    String firstName
    String lastName
    BigDecimal salary
}

There might be…

Welcome to another installation of This Week in Spring. As usual, we have a lot to cover. As this post goes up, the Cloud Foundry Open Tour is underway in Beijing, and coming to a city near you, soon. This show's a very unique opportunity to learn more about Cloud Foundry and Spring from the experts - don't miss out, register today.

1. Spring web dude Rossen Stoyanchev announced that Spring Web Flow 2.3.1 has been released. This is a maintenance release featuring an upgrade to Spring 3.1.1, and JavaServer Faces 2.1.7 along with a number of bug fixes.
2. SpringSource Tool Suite lead Martin Lippert announced the release of the Cloud Foundry Integration for Eclipse 1.0. This release brings a complete, cohesive Cloud Foundry integration for all Eclipse distributions, including the SpringSource Tool Suite.
3. Martin also announced the release of SpringSource Tool Suite release, 2.9.1, featuring new features and bug fixes.

4. Maciej Walkowiak has a blog that introduces how to use Spring 3.1 profiles in conjunction with some custom Tomcat configuration to activate Spring profiles without changing the deployed binary.
5. Michal Jastak has put together a wonderful post introducing how to use Spring MVC 3.1's support for flash attributes.
6. Tobias Flohre is at it again, this time with two posts on Spring Batch. The first post introduces the basics of transactions in Spring Batch, and the second post introduces some of the finer points of restarting cursor-based readers and writers.

7. Artur Mkrtchyan has a great post introducing both how to install Redis (a fast, highly optimized data-structure server) and how to use Spring Data Redis (part of the Spring Data umbrella project that facilitates access to the wide varieties of so-called NoSQL and big-data stores) to build Spring applications that talk to Redis.

Spring Web Flow 2.3.1 is now available for download. This maintenance release includes an upgrade to Spring 3.1.1, JavaServer Faces 2.1.7 along with a number of bug fixes. For those tracking the project it is now hosted on Github including a separate issue repository to help reproduce issues based on one of several project templates.

I am happy to announce the first release of the Cloud Foundry Integration for Eclipse 1.0.

This release features:

• deploying, updating, starting, stopping apps directly from your workspace
• supports Java/Web, Java/Spring, Groovy/Grails and Scala/Lift apps
• service creating and binding (directly at deploy time or later)
• instance scaling and statistics
• remote file browsing directly integrated
• full debugging support for Micro Cloud Foundry
• improved incremental update performance
• integrated into Eclipse and STS

And, last but not least, the project is now open-source under the EPL and available from GitHub: https://github.com/SpringSource/eclipse-integration-cloudfoundry

You can install it into STS (2.9.0 or higher required) using the STS Dashboard or directly into a plain Eclipse JEE package (Indigo recommended) using the Eclipse Marketplace.

Attention: if you have a previous version of the Cloud Foundry tooling installed (the old milestone or nightly builds, having the old STS version…

Dear Spring Community,

We're pleased to announce the update release 2.9.1 of the SpringSource Tool Suite (STS).

This update improves the Spring Integration graphical editing experience and fixes a performance problem with the content-assist in the Java editor when working inside a Spring project.

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.

Hello and welcome to another installment of This Week in Spring! As usual, we've got some great stuff to look at, so let's get to it.

1. 	Want to use SpringSource Tool Suite on the <a href = "http://blog.springsource.org/2012/03/14/early-access-springsource-tool-suite-for-eclipse-juno-4-2/">latest Eclipse Juno (4.2) milestone builds</A>?

Dear Spring Community,

I am pleased to announce that the first milestone of the Spring GemFire 1.2 project for Java is now available!

Downloads | JavaDocs | Reference Documentation | Changelog

This new milestone introduces:

• POJO mapping
• Repository support

For more information see the reference documentation.

Looking forward to your feedback!

Dear Spring Community,

I am pleased to announce the GA release of Spring GemFire 1.1.1 project is now available!

Downloads | JavaDocs | Reference Documentation | Changelog

To learn more about the project, visit the Spring GemFire Homepage.

1.1.1 is mainly a maintenance release providing several enhancements on the configuration front. See the changelog for more details.

In a press release today, SpringSource and VMware announced that the Spring 3.1 Release Train is complete. Spring Integration, Spring Security, Spring Batch, Spring Data, Spring Mobile and Spring for Android all now support Spring 3.1, making it easier and faster for enterprise developers to build the next generation of enterprise applications.

The press release also highlighted important findings from Evans Data Research regarding the growing popularity and benefits of using Spring. More than two thirds of Java developers are either using Spring today or plan to do so within the next two years and those that do use Spring are 50% more productive.

SpringSource would like to thank all of the amazing community members that made this release possible. Community contributions form an important part of many of the projects and all the users that experimented with milestone and release candidate versions help substantially in making sure that Spring technology is high quality and production ready. Work is already underway on many other exciting projects like the recently announced Spring for Apache Hadoop project. Community members are invited to attend the upcoming SpringOne on the Road events to meet the Spring experts and learn about the latest features available with Spring.
