Spring Boot DTO ↔ Entity Conversion | ModelMapper Made Easy

Mapping DTOs and Entities manually in Spring Boot can be repetitive and error-prone. In this tutorial, I’ll show you how to use ModelMapper to simplify DTO ↔ Entity conversion with just a few lines of code.

I will cover:
✅ Why DTOs are important in Spring Boot
✅ Creating DTOs and Entities (Book example)
✅ Using ModelMapper for automatic mapping
✅ Handling IDs and generated fields like ISBN
✅ Best practices for naming DTOs (BookRequest, BookResponse vs BookDTO)

By the end, you’ll know how to keep your APIs clean, secure, and maintainable without boilerplate code.
