Can you name the main architectural principles underlying the Spring Framework?

Main architectural principles of the Spring Framework:

• Inversion of Control (IoC) — dependency management is delegated to the Spring container, which creates and wires objects.
• Dependency Injection (DI) — objects receive their dependencies from outside, simplifying testing and modularity.
• Modularity — Spring consists of many modules (Core, MVC, Data, Security, etc.), which can be used independently.
• Aspect-Oriented Programming (AOP) — allows separation of cross-cutting concerns (logging, transactions) from business logic.
• Configuration via annotations and XML — flexible ways to configure the application.
• Transaction management — declarative transaction management without explicit code.

These principles provide flexibility, extensibility, and ease of development in Java using Spring.
