What is Spring Framework?

  • Spring is an open-source framework for Java-based applications.
  • Provides modular and flexible architecture for enterprise applications.
  • Used for backend development, microservices, and cloud applications.
  • Works with Spring Boot, Spring MVC, and Spring Security to simplify Java development.

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.
