Spring Data JDBC with Records

Apply Spring Data JDBC guidelines with Java records.

What is covered in this Skill?

• Records for entity classes (immutable, constructor-friendly)
• @Table for naming when record name differs from the table name
• @Embedded to inline value-object columns into the parent row without a separate table
• Repository pattern
• Immutable updates with static factories for new rows and with* helpers for updates
• save() INSERT vs UPDATE semantics driven by @Id nullability
• Aggregate boundaries: one repository per aggregate root, Set for one-to-many inside the root, foreign keys between aggregates
• Custom queries with @Query and named parameters (no user-input concatenation)
• Transaction management (@Transactional on services; readOnly where appropriate)
• Single query loading (N+1 avoidance)

Scope: Apply recommendations based on the reference rules and good/bad code examples.
