Overview
A REST API built with Java 21 and Spring Boot 3 for managing astronomical observatories and exoplanets. This API exposes a complete CRUD with pagination, filtering, partial updates and business-driven state transitions. It demonstrates advanced Spring Boot patterns: layered architecture, robust persistence via Hibernate with dirty checking and optimistic locking, centralized error handling in RFC 7807 (ProblemDetail), schema migration via Flyway, and interactive OpenAPI/Swagger documentation.
