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.
The framework also serves as the foundation for Spring Integration, Spring Batch and the rest of the Spring family of projects. Browse the repositories under the SpringSource organization on GitHub for a full list.
Instructions on downloading Spring artifacts via Maven and other build systems are available via the project wiki.
Spring's JIRA issue tracker can be found here. Think you've found a bug? Please consider submitting a reproduction project via the spring-framework-issues repository. The readme provides simple step-by-step instructions.
