Key Features of Spring Framework
- Inversion of Control (IoC) – Manages object dependencies automatically.
- Aspect-Oriented Programming (AOP) – Separates cross-cutting concerns like logging and security.
- Spring MVC – Framework for building web applications.
- Spring Boot – Simplifies Spring application setup with minimal configuration.
- Spring Data – Integrates with databases using JPA, Hibernate, and NoSQL.
