The Spring IoC (Inversion of Control) is a core component of the Spring Framework. It enforces the dependency injection pattern for beans, making them loosely coupled and allowing application developers to code with abstractions.

It is a process whereby objects define their dependencies only through constructor arguments, factory method arguments, and properties to be set on the object after it is constructed. The container then injects those dependencies when it creates the bean.
