Micronaut Data Guidelines

Apply Micronaut Data patterns for relational repositories and safe SQL.

What is covered in this Skill?

• @MappedEntity, @Id, @GeneratedValue, @MappedProperty for column mapping
• @Repository interfaces extending CrudRepository / PageableRepository
• Derived finder methods and @Query with named parameters
• @Transactional on @Singleton services (readOnly where appropriate)
• Page and Pageable for list endpoints
• DTO/interface projections for read-heavy queries
• @Version for optimistic locking
• Integration tests: @MicronautTest + TestPropertyProvider + Testcontainers

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

Constraints

Compile before persistence changes; verify the full build after.
