Questions tagged [spring-3]

Version 3.x of the Spring Framework, use [tag:spring] for general Spring related questions.

The Spring Framework is an open source application framework for the Java platform. Use for general Spring related questions. This tag is for questions that are specific to versions 3.x only.

It provides services and functionality across the application domain, including a core Inversion of Control container, technology-agnostic data-access and MVC layers, extensive AOP support, task scheduling, and various integration patterns designed to make distributed system development simpler and clearer. While some spring modules are simple wrappers and helpers over the Java EE specifications, the majority of them go far beyond the Java EE specification.

The latest Spring Framework Reference Documentation can be found here.
