Hibernate/JPA Validator

Currency

Last verified: 2026-07 (Hibernate ORM 7.x / Spring Boot 4.1 era; the 6->7 notes are checked against the official 7.0 migration guide). Facts here age. If the answer hinges on a version-sensitive fact — a Hibernate or Spring Boot major, a pinned artifact coordinate, a default that names a release — and time has passed since the stamp above, spot-check current release notes or the tool's own source before asserting it. When current docs disagree with this file, the docs win: say so and note the line is stale.

Overview

Full-spectrum Hibernate/JPA analysis inspired by Vlad Mihalcea's Hypersistence Optimizer. When reviewing any entity or JPA code, run the full checklist — not just what the user asked about. Performance is first-class, not an afterthought.

This skill targets ORM concerns (mappings, fetch plans, SQL generation, transactions, schema). It does not cover Jakarta Bean Validation constraints (@Valid, @NotNull, @Size, ConstraintValidator, validation groups) — defer those to a Bean Validation skill or general Spring guidance.

Core philosophy: show the generated SQL, explain the underlying JDBC behavior, then show the fix.
