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 The Service class below is not Read more…

I am happy to announce that the first milestone release (1.0.0.M1) for Spring for Apache Hadoop project is available and talk about some of the work we have been doing over the last few months. Part of the Spring Data umbrella, Spring for Apache Hadoop provides support for developing applications based on Apache Hadoop technologies Read more…

In this post, I'll look at Spring's org.springframework.beans.factory.FactoryBean<T> interface. The definition of this interface is: A FactoryBean is a pattern to encapsulate interesting object construction logic in a class. It might be used, for example, to encode the construction of a complex object graph in a reusable way. Often this is used to construct complex Read more…

One of the major features added in Spring Framework 3.1 M1 is the generic cache abstraction for transparently applying caching to Spring applications. Just like the transaction support, the caching abstraction allows consistent use of various caching solutions with minimal impact on the code. Purpose Caches are in general used to improve application performance by Read more…

Last month, almost 4 years after the initial 4.0 release, OSGi Alliance officially approved the OSGi service platform 4.2 release. The announcement headline featured the Blueprint Container Service, a new addition to the Compendium specification based on the programming model promoted by the Spring Dynamic Modules (also known as Spring OSGi) project. To quickly summarize Read more…

The CommonServiceLocator project was released this week on CodePlex with the general idea of providing an IoC container agnostic API for resolving dependencies using Service Location. Erich Eichinger from SpringSource contributed the Spring.NET implementation, thanks Erich! Here is the API so you get the basic idea public interface IServiceLocator : System.IServiceProvider { object GetInstance(Type serviceType); Read more…

Portability is a key factor in the Spring universe. We believe in portability at the framework level: Application components are written against a specific framework (or framework generation), such as Spring 2.5; the framework is then in turn responsible for adapting onto any underlying hosting environment. However, the specific application framework is above and distinct Read more…
