Spring

The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications – on any kind of deployment platform.

A key element of spring is infrastructural support at the application level: Spring focuses on the “plumbing” of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.

Spring is modular in design, allowing for incremental adoption of individual parts such as the core container or the JDBC support. While all spring services are a perfect fit for the spring core container, many services can also be used in a programmatic fashion outside of the container.
