Configuration Simplifications in Spring 3.0

Second in a series of posts on “Spring 3 Simplifications” started yesterday by Keith, I’d like to provide a very brief and hands-on introduction to Spring’s new @Configuration annotation and related support.

As those that followed the Spring JavaConfig project will know, a @Configuration-annotated class serves much the same role as a Spring XML file. It provides a code-centric way of declaring Spring bean definitions using nothing more than methods and annotations. You might call it Plain Old Configuration* :) This means that for simple situations, no XML will be required!

Groovy 1.7 released

The Groovy development team and SpringSource are very pleased to announce the final release of Groovy 1.7, the most popular and successful dynamic language for the JVM! After two betas and two release candidates, we’re are happy to deliver this new and very important milestone to our ever-growing user base.

Over the years, the Groovy project has managed to grow a community, but not only that, a very rich and active ecosystem of Groovy-related projects: the Grails web stack, the Griffon swing application framework, the Gant and Gradle build solutions, the Gaelyk lightweight toolkit for Google App Engine, the Gpars parallel system, the Spock testing frameworks and the GMock mocking library, the CodeNarc and GMetrics quality tools, and many more! With all these initiatives, the world is even groovier and we’re thankful these projects have helped us shape what Groovy is today.

MVC Simplifications in Spring 3.0

As Juergen and Arjen have mentioned, Java developers everywhere have a smooth upgrade with Spring 3.0. Now that Spring 3 is out, I’d like to take you through some of the new MVC features you may not know about. I hope you find these features useful and can start putting them to work in your web applications immediately.

This is also the start of a series on “Spring 3 Simplifications”, so expect more posts like these in the coming days and weeks.

Configuration Simplification

Spring 3 introduces a mvc namespace that greatly simplifies Spring MVC setup. Along with other enhancements, it has never been easier to get Spring web applications up and running. This can be illustrated by the mvc-basic sample, which I will now walk you through.

Spring Framework 3.0 goes GA

After a long ride, it is my pleasure to announce that Spring 3.0 GA (.RELEASE) is finally available (download page)! All of SpringSource is celebrating - join the party :-)

For some very recent news, Spring 3.0 GA is compatible with Java EE 6 final in terms of runtime environments now (e.g. on GlassFish v3 as released last week) and supports JPA 2.0 final already (e.g. using EclipseLink 2.0). We also support the newly introduced @ManagedBean (JSR-250 v1.1) annotation for component scanning now, which nicely complements our @Inject (JSR-330) support for annotation-driven dependency injection.

VI Java API and CloudTools

Steve Jin, the creator of The Virtual Infrastructure Java API or vSphere API, recently contributed the work he had done for the VMworld 2009 keynote sessions to the CloudTools repository.  CloudTools is the open source project that provides the core infrastructure provisioning and application deployment functionalities to Cloud Foundry.  Steve’s code not only demonstrates how a Java application can be deployed through the Cloud Foundry user-interface to a vSphere infrastructure, it also shows how easily one can add an adaptor to CloudTools to enable Java application deployments to different cloud providers.  The following is a re-print of the blog entry Steve wrote to announce the contribution at his VMware Infrastructure (vSphere) Java API Blog.

Logging Dependencies in Spring

This article deals with the choices that Spring makes and the options that developers have for logging in applications built with Spring. This is timed to coincide with the imminent release of Spring 3.0 not because we have changed anything much (although we are being more careful with dependency metadata now), but so that you can make an informed decision about how to implement and configure logging in your application. First we look briefly at what the mandatory dependencies are in Spring, and then go on to discuss in more detail how to set your application up to use some examples of common logging libraries. As an example I’ll show the dependency configuration using Maven Central style artifact naming conventions.
