The Spring Framework is an open source enterprise application framework licensed

under Apache License version 2.0, which provides an extensive toolset for building applications that

meet the enterprise demands. The idea itself came about because doing development with J2EE (the

former version of Java Enterprise Edition) introduced a good deal of complexity in the enterprise

world. Creating and deploying beans with Enterprise Java Beans (EJB) was a burden because, to

create one bean, you had to create home and component interfaces along with the bean definition.

Because the concept of dependency injection was also missing in the EJB world at those times, the

lookup approach was the only way to find objects or resources.
