SpringSource has just released Spring Integration 2.0. Spring Integration is a lightweight framework to help build event-driven and messaging oriented applications in the familiar Spring style. InfoQ caught up with project lead Mark Fisher to talk to him about the new release.
Spring Integration provides an extension of the Spring programming model to support the well-known Enterprise Integration Patterns. Following the announcement of RC 1 that became available this week InfoQ has a Q&A with SpringSource’s Iwein Fuld on key benefits, deployment scenarios and future directions of Spring Integration.

In this article Michael Poulin explores the different contexts in which SOA patterns are applied; how the products from different vendors influence these patterns and its effect on the responsibilities of business and IT.

Gregor Roth overviews the basics of RESTful HTTP and discusses typical issues that developers face when they design RESTful HTTP applications, showing how to apply the REST architecture style in practice. Gregor describes commonly used approaches to name URIs, discusses how to interact with resources through the Uniform interface, when to use PUT or POST and how to support non-CRUD operations.

In this article, Joshua Long introduces the readers to Spring Integration, an extension of the Spring framework supporting the Enterprise Integration Patterns. After a short introduction into Enterprise Application Integration (EAI), the article presents an example of the integration between an email application and a blogger one.

In this article, Adrien Louis and Marc Dutoo discuss the differences and relative merits of using orchestration vs. routing in a typical ESB setup. They discuss various approaches to connecting services, from low level ones like customized routing, to high-level ones using business oriented approaches like workflow and orchestration, and conclude that there is no one-size-fits-all solution.
Oleg Zhurakousky demoes performing transaction management, error handling, asynchronous processing, advanced aggregator configuration, etc., using Spring Integration and enterprise integration patterns.

InfoQ talks to Mark Fisher, project lead for the Spring Integration project, about the framework. The interview talks about the origins of the framework, how it compares to using an ESB, and using Spring Integration with Spring Batch.
