What is Spring used for?

The Spring Framework is used for creating enterprise applications in Java. It simplifies development by providing infrastructural components:

• Dependency Injection: Managing the lifecycle of objects and their dependencies, reducing code coupling.
• Aspect-Oriented Programming (AOP): Allows separation of cross-cutting concerns (logging, security, transactions) from the main business logic.
• Data Access: Simplifies working with databases via JDBC, ORM (Hibernate, JPA), NoSQL.
• Web Development: Provides tools for creating web applications (MVC, REST APIs).
• Transaction Management: Declarative transaction management.
• Integration: Supports integration with other frameworks and technologies.

The main goal of Spring is to increase developer productivity and create easily testable, scalable, and maintainable applications.
