Implement DDD patterns in Spring Boot by using aggregate roots with domain events, value objects, and repositories. This Skill automates wiring aggregates, @Embedded value objects, AbstractAggregateRoot, and transactional services aligned with Spring Boot 4 and Jakarta EE 11, ensuring immutability and per-aggregate transactions.

Use EntityGraph with Spring Data JPA to batch-load related entities and avoid N+1 query problems. This Skill demonstrates EntityGraph configuration within a DDD-structured data layer, optimizing read patterns while maintaining domain boundaries.

Configure projections in Spring Data JPA to fetch only required fields for read models, reducing payload and improving query performance. This Skill includes projection patterns integrated into a DDD data layer for efficient, denormalized reads.

Yes, Spring Data JDBC works with DDD aggregates and domain events. This Skill supports both JPA and JDBC persistence, applying aggregate roots, value objects, and transactional services for domain-driven designs regardless of ORM choice.

Spring Data provides auditing annotations for created and modified timestamps. This Skill demonstrates integrating auditing within a DDD structure, maintaining domain model purity while capturing temporal metadata automatically.

Entities have identity and lifecycle; value objects are immutable and identified by attributes. This Skill uses @Embedded value objects for immutability and shows how to structure repositories and aggregates to enforce these distinctions in Spring Boot 4.
