The Spring Framework is an open-source framework for application development on the Java platform. At its core is rich support for component-based architectures, and it currently has over twenty highly integrated modules.

The Spring Framework is an open-source application framework for the Java platform.

Spring is a non-invasive, versatile, robust framework.

Spring framework complements the Java EE APIs but is not a replacement for Java EE. It reduces most boilerplate code, reducing the burden on developers.

Spring provides services and functionalities 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 more uncomplicated and more straightforward. While some Spring modules are simple wrappers and helpers over the Java EE specifications, most go far beyond the Java EE specification.

The latest Spring Framework Reference Documentation can be found here.
