🚀 Spring Boot Best Practices (Beginner-Friendly)

1. 📁 Use Proper Project Structure

Follow a layered architecture:

com.example.project
 ├── controller   → Handles HTTP requests
 ├── service      → Business logic
 ├── repository   → Database interaction
 ├── model/entity → Data objects
 └── config       → Configuration classes

👉 Keep things separated—don’t put all logic in one class.

=> ⚙️ Use @Service, @Repository, @Controller Properly

Spring provides annotations to define roles:

• @RestController → for APIs
• @Service → business logic
• @Repository → database access

👉 This improves readability and maintainability.

---

=>  📦 Use DTOs (Data Transfer Objects)

Avoid exposing your database entities directly.

Instead:

Entity → DTO → Controller → Client

👉 This improves security and flexibility.
