Structure a Spring Boot REST API using a strict controller, service, and repository layered architecture to ensure scalable backend design. Apply consistent DTOs and centralized error handling to maintain separation of concerns across typical enterprise scenarios.

Centralized exception handling in Spring Boot standardizes error responses across architectural layers. Apply consistent validation and error handling patterns to catch errors uniformly across REST APIs and layered services without scattering logic.

Configure caching and async processing in Spring Boot applications using architectural patterns for scalable services. Apply these patterns to manage data access and background tasks across typical enterprise scenarios without blocking main threads.

You need DTOs and validation in a layered Spring Boot architecture to enforce data integrity between REST API boundaries and internal services. Consistent DTO usage decouples internal entities from external API contracts.

Spring Boot layered architecture supports scalable data access by applying pagination and repository patterns. Configuring data access layers with pagination controls memory consumption across typical enterprise scenarios with large datasets.

Spring Boot controllers bypassing service layers indicate a broken layered architecture. Enforce a strict controller to service to repository structure to maintain scalable backend design and proper business logic encapsulation.
