What problem does it solve?
Many Spring Boot APIs lack consistent, discoverable, and testable API documentation which makes integration, testing, and client generation error-prone and slow. This Skill provides patterns and configuration to produce clear OpenAPI 3.0 specifications and an interactive Swagger UI so teams can explore, validate, and consume REST endpoints reliably.
Core Features & Use Cases
- Automatic OpenAPI generation for Spring Boot 3.x using SpringDoc with WebMvc and WebFlux support.
- Controller and model annotation patterns to document operations, request/response schemas, validation constraints, and examples.
- Security documentation for JWT, OAuth2, Basic Auth and API keys with global security scheme configuration and per-endpoint SecurityRequirement usage.
- Advanced customization including grouped APIs, pagination parameter support, operation customizers, hiding internal endpoints, and build-time spec generation via Maven/Gradle plugins.
- Use Case: Add SpringDoc to a microservice, annotate controllers and DTOs, configure package scanning and security schemes, then publish a stable OpenAPI JSON/YAML and Swagger UI for frontend and client SDK teams.
Quick Start
Add the springdoc starter dependency to your Spring Boot project, annotate controllers and DTOs with OpenAPI annotations, configure springdoc properties or an OpenAPI bean, then open the Swagger UI endpoint to verify the generated documentation.
