To generate Spring Boot REST controllers and services from an OpenAPI specification, use this Skill to implement backend logic following contract-first principles, producing service layers, JPA repositories, entities, and DTOs.

Contract-first API development in Java Spring Boot 3.4 involves defining your REST API via an OpenAPI specification before writing code, ensuring strict context isolation, code quality, and security constraints throughout the generated backend service implementation.

Yes, you can automatically generate JPA repositories and DTOs for your Spring Boot application by providing an OpenAPI contract, which this Skill uses to implement the full backend stack including data validation and comprehensive unit tests.

Yes, generating unit tests for Java Spring Boot REST APIs is supported directly from the OpenAPI specification, ensuring comprehensive test coverage alongside the automatically generated controllers, service layers, and data persistence entities.

The best way to enforce code quality and security constraints in Spring Boot backend services is using a contract-first implementation approach that automatically applies strict context isolation and standardized architecture rules derived from your OpenAPI specification.
