What problem does it solve?
It eliminates fragile and inefficient persistence code by providing production-grade patterns for entity modeling, repository design, query optimization, transaction boundaries, auditing, and Flyway-aligned database changes.
Core Features & Use Cases
- Entity design & safety rules: Consistent JPA mappings, lifecycle listeners (auditing), optimistic locking, and domain-method state transitions to prevent illegal updates.
- Performance-focused querying: N+1 detection guidance, JOIN FETCH / @EntityGraph patterns, pagination usage, and Hibernate batch fetch tuning.
- Repository & transaction patterns: Specification-ready repositories, JPQL/Criteria-friendly query shapes, @Modifying with transactional updates, and readOnly transaction defaults.
- Flyway migration alignment: Practical rules for when entity changes require migrations and how to apply zero-downtime column/index changes safely.
- Connection pool tuning: HikariCP configuration defaults aimed at stable throughput and predictable latency.
Quick Start
Use spring-jpa when designing a new database entity and its repository methods, then ask it to propose the entity mapping, repository API, transactional boundaries, and the required Flyway migration steps.
