Spring CRUD Generator (v1.0.0): Generate Spring Boot CRUD, Flyway, tests & more from YAML/JSON

#java #springboot #opensource #webdev

I just open-sourced Spring CRUD Generator (v1.0.0) — a Maven plugin that generates a production-ready Spring Boot backend from a single YAML/JSON spec.

The goal: less boilerplate, consistent structure, and faster iteration.

What it can generate (depending on configuration)

CRUD stack: entities, repositories, services, mappers, REST controllers
Flyway migrations (incremental change detection via state files)
OpenAPI specs + optional resource generation
Dockerfile + docker-compose
Unit tests + test data generation (Instancio/Podam)
Caching (Redis/Caffeine)
GraphQL

Maven coordinates

      type: LocalDate
    fields:
      - name: id

Quick start

Add a Maven profile and run the generator goal (see README for the full setup and configuration reference).

mvn clean install -Pgenerate-resources -DskipTests
