Spring Boot REST API Project with complete explanation of Stereotype Annotataions, 3-Layer Architecture and Spring Web annotations.

Understanding the difference between Stereotype Annotations (@Component, @Service, @Repository) and REST Mappings (@GetMapping, @PostMapping) is the "secret sauce" to writing professional, scalable code. In this video, we build a real-world Student Management API from scratch to see how these annotations work together to create a clean, 3-layer architecture.
