📚 IS VIDEO MEIN AAP SIKHENGE:

✅ Spring Annotations ka proper use
✅ @Component vs @Service vs @Repository difference
✅ @Autowired ki working aur best practices
✅ Multiple implementations handle karna (@Primary, @Qualifier)
✅ Bean lifecycle aur scope (Singleton, Prototype)
✅ Layered architecture implementation
✅ Service layer, Repository layer separation
✅ Real-world Spring application structure

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🎯 KEY CONCEPTS COVERED:

🔹 Stereotype Annotations
• @Component - Generic bean
• @Service - Business logic layer
• @Repository - Data access layer
• @Controller - Presentation layer

🔹 Dependency Injection
• Constructor injection (recommended)
• Setter injection
• Field injection

🔹 Ambiguity Resolution
• @Primary annotation
• @Qualifier annotation
• Bean naming strategies

🔹 Bean Lifecycle
• Creation & initialization
• Dependency injection phase
• Custom init/destroy methods
• @PostConstruct & @PreDestroy

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🏗️ LAYERED ARCHITECTURE:

Controller Layer → Service Layer → Repository Layer → Database

✅ Clean separation of concerns
✅ Easy to test
✅ Maintainable code structure
✅ Industry standard approach
