Can you name the main architectural patterns used in the Spring Framework?

Main architectural patterns used in the Spring Framework:

• MVC (Model-View-Controller) — dividing the application into model, view, and controller to simplify development and maintenance.
• Dependency Injection (DI) — managing object dependencies through the Spring container, which enhances modularity and testability.
• Aspect-Oriented Programming (AOP) — separating cross-cutting concerns (e.g., logging, security) into separate aspects.
• Template Method — using template methods in various patterns, such as JdbcTemplate for database operations.
• Singleton — most beans in Spring are singletons by default, ensuring a single instance per context.

These patterns help create flexible, extensible, and maintainable applications.
