Less popular Spring tricks: no Hibernate, rest repo, projections

Typical Spring project

• JPA (usually Hibernate ORM), @Entity classes here and there, Flyway for DB migrations
• Spring Data - SQL for above classes; especially JpaRepository
• Entity-DTO mapping, usually done by hand
• @Controller or @RestController exposing DTOs

This project

• Still with Flyway
• Still with Spring Data
• No JPA, no "manual" mappings, fancy REST (HATEOAS)
• And MOAR!
