Spring is a Java/J2EE application framework that assembles components via configuration files. Spring is an open source project but is developed by engineers with Interface 21, and Spring Framework is a trademark of Interface 21. Spring is supported by a number of companies including Interface21 and SourceLabs, and is covered in SourceLabs Self-support Suite for Linux and Open Source Java

Spring’s core technical selling point has been the Inversion of Control design idea, where programming is focused on interfaces rather than classes. Spring’s design comes from the book Expert One-on-One J2EE Design and Development by Rod Johnson.

Mission

Spring’s mission statement as articulated by Interface21 includes these points:

1. J2EE should be easier
2. Interfaces > Classes
3. JavaBeans are good for configuration
4. OOP > implementation technology (J2EE)
5. Testability is important and should be easier
6. Frameworks shouldn’t force recoverable exception catching

And these direct points about Spring

1. Spring should be a pleasure to use
2. Spring APIs should not be a dependency
3. Spring should not compete with good existing solutions like JDO and Hibernate.
