spring-persistence

What problem does it solve?

It removes the guesswork and risk when building production-ready persistence layers by providing clear, secure patterns for JPA entities, repositories, schema migrations, caching, and document-store integration so teams avoid common pitfalls like incorrect mappings, N+1 queries, and unsafe migrations.

Core Features & Use Cases

• JPA entity design with recommended annotations, UUID id generation, optimistic locking, and database-safe enums to ensure reliable domain modeling.
• Spring Data repositories & specifications including derived queries, JPQL, projections, pessimistic locks for balance updates, and dynamic filtering for pageable APIs.
• Flyway migration guidance and naming conventions to maintain safe, sequential schema evolution in CI/CD.
• MongoDB audit/event document patterns and Redis caching best practices for audit stores and read-performance with Cacheable/CacheEvict semantics.
• MapStruct mapping patterns and practical advice to avoid exposing entities across boundaries and to keep mappers build-strict.

Quick Start

Generate production-ready JPA entity, Spring Data repository with specifications, Flyway migration, MapStruct mapper, and Redis cache configuration for an Account aggregate with optimistic locking and database indexes.
