Lightweight : Spring is lightweight when it comes to size and transparency. The basic version of spring

framework is around 1MB. And the processing overhead is also very negligible.

Aspect oriented (AOP) : Spring supports Aspect oriented programming and enables cohesive development

by separating application business logic from system services.

Container : Spring contains and manages the life cycle and configuration of application objects.

Framework : Spring provides most of the intra functionality leaving rest of the coding to the developer.
