spring-boot-crud-patterns

Structure a Spring Boot CRUD API by organizing code into domain, application, presentation, and infrastructure layers. This approach separates entities, repositories, controllers, and DTOs to ensure maintainability across REST endpoints.

A feature-focused architecture for Spring Data JPA REST APIs groups code by business feature rather than technical layer. This workflow models aggregates, repositories, and DTOs together, ensuring clear boundaries across domain and presentation layers.

Scaffold a Spring Boot 3 REST controller and JPA entity by modeling the aggregate, creating a repository interface, and mapping DTOs. This workflow generates service logic and controllers complete with validation for REST APIs.

Yes, building CRUD services with this workflow requires Java 17+ and Spring Boot 3.5+. You also need standard starter dependencies for web and JPA to establish the REST API and persistence layers.

Implement DTO mapping and validation in Spring Boot CRUD operations by separating presentation layer DTOs from domain aggregates. This feature-focused workflow ensures controllers handle REST API mapping while services manage business logic.

Avoid a feature-focused CRUD workflow for Spring Boot microservices when your application requires complex domain logic that exceeds standard Create, Read, Update, Delete operations or does not fit aggregate modeling patterns.
