    Entities and identity

    • Mapping tables to entities, and what Hibernate does with them
    • Identity, generated keys, equals and hashCode done correctly
    • Value objects and embeddables
    • Why the entity is a persistence concern, not an API one

    What you will build

    An entity whose equality survives persistence, proved by the test that fails for the naive version.

Detailed course information

Full course brief

JPA is the most-used and least-understood layer of the Java stack. Everyone ships it; almost nobody can say when the SQL actually runs, why the update saved without save(), or where the four hundred extra queries came from.

This week is the opened black box. The SQL log stays visible in every session, and every claim about Hibernate's behaviour is proved in it.

Who this is for

You need a working Spring Boot API, the depth taught in Spring Boot REST API, whose project this week picks up and gives a real persistence layer.

Where it leads

Straight into Spring Security on the Full-Stack Developer (Java) and Backend Developer (Java) pathways.
