There is always a choice. Spring Data JDBC vs. Hibernate. Taras Boychuk. Java Fest 2020 Online
summary
Compares Hibernate’s full JPA stack (Spring Boot, H2, Spring Data JPA, Lombok, Flyway) with Spring Data JDBC and demos a small app with Person and Note entities. Shows that without @Transactional required updates don’t flush, that adding Cascade.PERSIST fixes orphan inserts, and that default lazy loading causes n+1 selects and depends on Open Session in View. Explains Hibernate internals: session/persistence context, action queue and flush ordering, and argues Spring Data JDBC is simpler—no session, no dirty‑checking, aggregate‑root oriented.
