spring-boot-data-ddd

A Spring Boot 4 data-layer implementation tailored for Domain-Driven Design (DDD). Use this when implementing JPA or JDBC aggregates, Spring Data repositories, transactional service boundaries, projections, or entity auditing. It includes support for aggregate roots via AbstractAggregateRoot, mapping and persistence of value objects, and use of EntityGraph or fetch-joins to prevent N+1 select issues. Also covers Spring Boot 4 specifics such as JSpecify null-safety annotations and AOT-compatible repository patterns for native-image readiness.
