SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Spring REST API Skill provides a ready-to-use scaffold for building production-grade REST endpoints in Java 21 / Spring Boot 3.x, including controllers, DTOs, validation, and OpenAPI docs, reducing boilerplate and enabling consistent API design.

Core Features & Use Cases

  • Controller skeletons with @RestController and standard HTTP methods
  • DTOs and validation using Jakarta Validation and Java records
  • OpenAPI / Swagger scaffolding with SpringDoc for automatic API docs
  • Global error handling with a RFC 9457 ProblemDetail-based exception system
  • Versioning and routing with /v1 (and future /v2) prefixes to preserve compatibility

Quick Start

Create a sample REST controller with a GET endpoint and view the generated OpenAPI docs at /v1/docs

FAQPage Schema
How do I scaffold a Spring Boot REST API with DTOs and validation?▼

Scaffolding a Spring Boot REST API is automated by generating @RestController skeletons, Java record DTOs, and Jakarta Validation annotations to enforce data integrity in HTTP endpoints.

What is the best way to generate OpenAPI documentation for a Spring Boot 3.x project?▼

Generating OpenAPI documentation for Spring Boot 3.x uses SpringDoc OpenAPI scaffolding to automatically produce API docs, viewable at the /v1/docs endpoint after creating your HTTP controllers.

Does this REST API scaffold support global error handling with RFC 9457?▼

Yes, global error handling supports RFC 9457 by generating a ProblemDetail-based exception system that standardizes HTTP error responses across your Java 21 Spring Boot controllers.

Can I use this to build REST controllers with versioned routing in Spring Boot?▼

Building versioned REST controllers is supported by generating routing prefixes like /v1 to preserve backward compatibility, ensuring existing HTTP endpoints remain stable for future API iterations.

What dependencies do I need to build production-grade Java REST APIs with this approach?▼

Building production-grade Java REST APIs requires Spring Web MVC, Lombok, Jakarta Validation, SpringDoc OpenAPI, and a Gradle build configuration integrated into a Java 21 Spring Boot 3.x environment.
