Chapter 1. Preface

Developing software applications is hard enough even with good tools and technologies. Spring provides a light-weight solution for building enterprise-ready applications. Spring provides a consistent and transparent means to configure your application and integrate AOP into your software. Highlights of Spring's functionality are providing declarative transaction management for your middle tier as well as a full-featured ASP.NET framework.

Spring could potentially be a one-stop-shop for many areas of enterprise application development; however, Spring is modular, allowing you to use just those parts of it that you need, without having to bring in the rest. You can use just the IoC container to configure your application and use traditional ADO.NET based data access code, but you could also choose to use just the Hibernate integration code or the ADO.NET abstraction layer. Spring has been (and continues to be) designed to be non-intrusive, meaning dependencies on the framework itself are generally none (or absolutely minimal, depending on the area of use).

This document provides a reference guide to Spring's features. Since this document is still to be considered very much work-in-progress, if you have any requests or comments, please post them on the user mailing list or on the support forums at

Before we go on, a few words of gratitude are due to Christian Bauer (of the Hibernate team), who prepared and adapted the DocBook-XSL software in order to be able to create Hibernate's reference guide, thus also allowing us to create this one. Also thanks to Russell Healy for doing an extensive and valuable review of some of the material.
