Spring Boot POST API: DTO Mapping & Validation (Enterprise Way | Hindi)

This tutorial shows how to build a clean Spring Boot POST API using DTOs, validation, and entity mapping, following a typical enterprise architecture approach. Chapters 00:00 API Architecture and Project Setup 04:32 Model Class Creation 13:23 Implementing the POST API Endpoint 15:15 Creating the Request DTO 18:13 Creating the Service Layer 20:56 Adding Validation with Jakarta Validation 26:05 Mapping DTO to Entity 29:54 Persisting Data with Spring Data JPA 31:41 Testing the POST API 34:02 Creating Global Exception Handler 39:23 Recap: Enterprise API Pattern for POST API This video is useful for developers learning Spring Boot REST APIs, DTO design, validation with Jakarta Validation, and clean enterprise API architecture. In real-world Spring Boot enterprise applications, POST APIs are rarely implemented directly using entities. Instead, we use DTOs, validation, and mapping layers to keep our API secure, maintainable, and production-ready. In this video, we implement a clean POST API in Spring Boot using: • DTOs for request handling • Bean Validation for input validation • Manual mapping from DTO → Entity • Clean persistence using Spring Data JPA This approach is commonly used in enterprise backend systems to avoid exposing entities directly and to maintain clear API contracts. Topics covered • Why entities should not be used directly in APIs • Designing request DTOs • Adding validation using Jakarta Bean Validation • Mapping DTOs to entities • Implementing a clean POST API in Spring Boot Tech stack Spring Boot Spring Data JPA Jakarta Validation REST APIs Subscribe for more backend engineering content If you want to learn real-world Spring Boot architecture, enterprise API patterns, and clean backend design, subscribe to DeepCoder.
