What is Inversion of Control (IoC) in the Spring Framework?

Inversion of Control (IoC) is a design pattern in software development where the control flow of a program is inverted. In the context of the Spring Framework, IoC refers to the process in which the control of creating and managing objects is shifted from the application code to the Spring Framework.

IoC is achieved in the Spring Framework primarily through Dependency Injection. Dependency Injection is a technique where objects are given their dependencies rather than creating them internally. This allows for loose coupling between components and better separation of concerns.

The Spring Framework provides several ways to implement IoC, such as using XML configurations, Java annotations, or Java-based configurations. By leveraging these mechanisms, developers can easily manage dependencies and promote modularity and reusability in their applications.

In summary, Inversion of Control in the Spring Framework simplifies the development process by delegating the management of object dependencies to the framework, resulting in more flexible, maintainable, and testable code.
