To enforce clean Java backend architecture in a Spring Boot project, separate controller, service, repository, and domain layers while ensuring consistent DTO usage and shared error handling conventions. This prevents direct entity exposure and maintains API contract integrity.

Using DTOs instead of entities in Spring Boot controllers maintains API contract integrity and enforces clean layered architecture. DTO pattern adherence ensures that database entities are never directly exposed to controllers, keeping API responses consistent and secure.

The best way to standardize error handling in a Spring Boot backend is to use shared exception types and specific ErrorCode objects. This promotes consistent API responses across the project and ensures maintainable error tracking throughout all architectural layers.

To structure a new feature using domain-driven design in Java, place data access methods in the repository layer and business logic in the service layer. Maintain strict separation between controller, service, repository, and domain layers to ensure project consistency.

No, this architecture skill applies specifically to Java code within the novacore repository, particularly under src/main/java/com/novacore. It enforces project-specific patterns for API endpoints, business logic, persistence, and domain modeling within that scope.
