java-jpa-hibernate — Claude Code skill: what it does, how to install
Guides JPA entity mapping, query tuning, and transaction controls for Java persistence layers in production.
npx skills add pluginagentmarketplace/custom-plugin-java --skill java-jpa-hibernate -a claude-codeWhat java-jpa-hibernate does
This skill guides assistants through entity modeling, Spring Data repositories, and Hibernate tuning. It focuses on targeted relational engines: postgresql, mysql, oracle, and h2. You get clear patterns for audit listeners, lifecycle callbacks, and locking strategies.
The included guidance tackles query bottlenecks. It outlines when to apply JOIN FETCH, dynamic @EntityGraph declarations, batch fetching with @BatchSize, or lightweight DTO projections. Configuration recipes cover HikariCP connection limits and second-level cache controls.
Leaving open-in-view enabled masks architectural defects until database traffic spikes unexpectedly during response rendering.
What it helps with
- eliminate N+1 select bottlenecks in Spring Data queries
- map bidirectional entity relationships with audit fields
- configure JDBC batching and HikariCP connection pools
- apply optimistic or pessimistic locking to transactions
Example prompts for the agent
- Refactor this repository query to use a DTO projection and prevent LazyInitializationException.
- Configure batch insert properties and connection pool limits for PostgreSQL in application.yml.
- Add an @EntityGraph to fetch order items and avoid secondary queries.
