We are pleased to announce that the 1.2.0.RELEASE is now available for Java.

Following the Release Candidate, this GA release includes a minor bug fix and updates the default RabbitMQ client to 3.1.3. See the Release Notes for details of these changes.

Major changes over and above the 1.1.x release are highlighted in the What's New section of the reference manual.

Please see the Project page for more information including links to documentation and downloads.

We are happy to announce a new release candidate 1.0.1.RC1 for the Spring for Apache Hadoop project. This release candidate introduces support for Apache Hadoop 1.1.2, Hortonworks HDP 1.2, Apache Hadoop 2.0.3-alpha as well as support for Pivotal HD 1.0. The support for these versions are in addition to the already supported versions of Apache Hadoop 1.0.4 and Cloudera CDH 3 and CDH 4. This brings us to support for no less than 7 different Hadoop versions.

To make it easier to configure project builds using these varying versions we will be introducing specific flavors of the Maven artifacts…

Are you an Eclipse user? Do you want a fast and easy way to search for text snippets and patterns in your workspace? Then read on!

A new "Quick Search" is included in Spring ToolSuite (STS) 3.3.0 and Groovy Gails Tool Suite (GGTS) 3.3.0 which have just been released. Even if you are not a Spring or Grails developer, you might be interested in this Feature because it can also be installed separately into a vanilla Eclipse.

Introducing the Quick Search Dialog

The Quick Search dialog is designed to do just one thing and do it well: use simple text searches to quickly navigate around your workspace.

You open the dialog by pressing CTRL+SHIFT+L (or CMD+SHIFT+L on Mac):

The Power of Simplicity

Unlike the standard Eclipse search UI, QuickSearch UI is extremely simple. Nothing to configure (e.g. no need to define a search Scope create a workingset etc.). There's just a single search text box. Start typing and see the results appear immediately and update instantly as you type. Use the arrow keys to select a result and press enter to navigate to it. You can also hit enter immediately to open the first result.

Of course you can also use the mouse if you want to, but there's no need for your hands to leave the keyboard…

In this post, I will discuss how to make your Spring Security Java configuration more readable. The post is intended to elaborate on a point from Spring Security Java Config Preview: Web Security where I stated:

By formatting our Java configuration code it is much easier to read. It can be read similar to the XML namespace equivalent where "and()" represents optionally closing an XML element.

Indentation

The indentation of Spring Security's Java configuration really impacts its readability. In general, indentation like a bullet list should be preferred.

For a more concrete example, take a…

Welcome to another installment of This Week in Spring. There's a lot of good stuff this week, including content on Apache Tomcat, Spring Security's new Java configuration updates, Spring Batch's Java configuration support, and so much more! We're fast approaching the August price increase for SpringOne2GX 2013 so register now and lock in the lower rate. Ok -- Let's get to it!

1. Craig Walls has announced that Spring Social 1.1.0.M3 (including revs to Spring Social, Spring Social Facebook, and Spring Social Twitter) is now available. The new release has a lot of compelling features including a new ReconnectFilter, support for OAuth 2's 'state' parameter to prevent CSRF attacks, and initial support for Twitter's streaming API.
2. Spring Security lead Rob Winch never sleeps. Also, he's just put together several very interesting posts on the brand new Spring Security Java configuration support. He starts the series with an introductory post. The second post covers the details of method-level security (fine-grained access control at the level of individual method invocations). The third post covers the details of web-based security (intercepting HTTP requests). The last post looks at how to use Java configuration to configure Spring Security OAuth. These posts are definitely worth a read! If you love these posts as much as I do, would you please upvote them on DZone?
3. Have you guys been following Spring XD's development? It's really coming along nicely! One thing that caught my eye recently? The amazing Andy Clement, designer and implementer of the amazing Spring Expression Language (SpEL), and a major contributor to the amazing tooling in the Spring Tool Suite and Grails Tool Suite, is now putting his amazing talents to work building a DSL for Spring XD jobs. To learn more, and to feedback on use cases that might be valuable to you, check out the JIRA.

Dear Spring Community,

we are happy to announce the next major release of our Eclipse-based tooling today: The Spring Tool Suite (STS) 3.3.0 and the Groovy/Grails Tool Suite (GGTS) 3.3.0.

Highlights from this release include:

• Eclipse Kepler Release updates (including Mylyn, EGit, m2e, m2e-wtp)
• updated bundled tc Server to 2.9.2 and bundled Spring Roo to 1.2.4
• ready for Spring 4
• support for JavaConfig-driven Spring projects (including navigation support for @Autowired)
• new and unified "New Spring Project" wizard
• additional performance improvements for working with Spring projects
• brand new instant and lightning fast quick search for your workspace
• GGTS now includes grails 2.2.3

We continue to ship distributions on top of the latest Eclipse release (Eclipse Kelper 4.3) as well as Eclipse Juno 3.8. While the 3.8-based version ships with all the components from Eclipse Juno, only the 4.3-based version ships on top of the just released Eclipse Kepler 4.3 version and is therefore the only distribution that comes with all the latest fixes and…

Sure the new features coming out in Spring Framework 4.0 are super exciting, but what about those of us that are still explaining dependency injection to our junior developers? And while Spock, Geb, and spring-test-mvc are revolutionizing our ability to test applications, what about the senior developers that are still justifying the value of unit testing to their managers. Strong technical leadership can overcome the organizational inertia that often resists your team's adoption of Spring technologies. Improve your leadership skills by drawing from lessons that were learned during the process of migrating Liberty University's software development department from "cut-and-paste coding" in ColdFusion to enterprise grade application development on the Spring Framework. Learn to plan an effective technology adoption strategy that avoids "new technology overload" and balances the pace of technology improvement with the necessity to continue production. Relationships with managers, junior developers, and production system administrators will all be important. Gain a better xtunderstanding of nontechnical managers and explore strategies for providing the conte they need to make the right decisions. Examine ways to build mentoring plans for your junior developers that include but extend beyond training and certifications from SpringSource University so that you can spend less time teaching and more time coding.

This is the fourth post in my five part blog series that introduces Spring Security Java configuration. In this post, we will discuss how Spring Security Java configuration can be extended by walking through Spring Security OAuth Java configuration support.

Proof of Concept

While the Spring Security Java configuration works well for very basic configuration, it is just a proof of concept. We have not ensured that all the functionality available in the XML namespace is present within its Java configuration support. It was important to ensure that Spring Security's Java configuration would work…
