Key Concepts Covered

Spring Boot 3

• Core functionality and annotations.
• Java-based configuration (no XML).
• REST API and MVC development.
• Hibernate/JPA integration for CRUD operations.
• Advanced features like Spring Boot Actuator and Dev Tools.
• Maven for project configuration and dependency management.

Spring Framework 6

• Dependency Injection (DI) and Inversion of Control (IoC).
• Spring Beans, Component scanning, and Autowiring.
• Aspect-Oriented Programming (AOP) for cleaner code.

Hibernate/JPA

• Object-to-Relational Mapping (ORM).
• CRUD operations and advanced mappings: One-to-One, One-to-Many, Many-to-Many.

Spring Security

• Role-based authentication and authorization.
• Secure login/logout functionality.
