Structure a Kotlin Spring Boot backend using reusable patterns for clean architecture, defining domain models as data classes, implementing services with clear boundaries, and exposing endpoints with typed DTO mapping and centralized error handling.

The best way to handle exceptions in a Spring Boot REST API is by applying centralized error handling with typed exceptions and global advice, ensuring consistent error responses across all service layers and controllers.

Define OpenAPI contracts for Kotlin Spring Boot services by using OpenAPI-driven interfaces for controllers, standardizing request and response DTOs, and applying mapping helpers to enforce functional API requirements.

Yes, you can use these Spring Boot patterns for large enterprise applications. They standardize backend development and apply to projects spanning from small microservices to large enterprise REST APIs.

Implement transaction handling and idempotency in Spring Boot services by applying the Service Pattern, which establishes clear boundaries and ensures reliable data processing for backend service layers.
