Introduction:

The Spring Framework is an open-source, powerful framework for building enterprise-level applications.

In this guide, we’ll explore the main components of Spring and dive into examples to demonstrate their usage.

1.Spring Core: The Heart of Spring Framework

⭐Introduction to Spring Framework:

Spring is a lightweight, modular, and powerful framework used to develop Java applications efficiently. It provides features such as Dependency Injection (DI), Aspect-Oriented Programming (AOP), and integrations with databases, web applications, and microservices.

✅ Why use Spring?
