A foundational based learnings on spring and spring boot and connection with database too.

A Spring Core project that dynamically selects encryption algorithms (AES, RSA, SHA) using the FactoryBean pattern and external configuration. It demonstrates clean design principles like dependency injection and strategy-based architecture for flexible, scalable encryption handling.

A simple Spring Core project demonstrating Dependency Injection (DI) and Inversion of Control (IoC) using annotation-based configuration. It generates an invoice by calculating product cost and applying tax through loosely coupled components.

A modular Spring-based notification system that uses the Factory Design Pattern and dependency injection to dynamically send messages via Email, SMS, and Push channels. It ensures scalability, loose coupling, and easy extension by simply adding new notification implementations without modifying existing code.

A simple Spring Core project demonstrating Dependency Injection using annotation-based configuration and component scanning. It shows how Spring manages object creation and wiring between Laptop and LaptopService using IoC.

A Spring Core application that uses the Factory Design Pattern to dynamically create food objects based on user input. It leverages dependency injection and component scanning for a clean, scalable, and annotation-based configuration.
