How does Hibernate automatically update an entity without calling an update method? Where does the EntityManager come from, and what exactly does Hibernate store inside the Persistence Context? In this Hibernate deep-dive lecture, we explore how Hibernate works internally in a Spring Boot application. Topics covered: JPA specification vs Hibernate provider EntityManagerFactory and EntityManager Hibernate SessionFactory and Session Persistence Context explained from first principles How @PersistenceContext works internally Shared EntityManager proxy in Spring How @Transactional works using Spring AOP Transaction boundaries and Unit of Work Complete Hibernate transaction flow Transient, Managed, Detached and Removed entity states Dirty checking and automatic update queries Difference between flush() and commit() Hibernate’s transactional write-behind mechanism First-level cache and identity mapping persist(), merge(), remove(), detach(), clear() and refresh() Using flush() and clear() during batch processing By the end of this lecture, you will understand that Hibernate does not simply convert method calls into SQL. It manages entity state inside a Persistence Context and synchronizes those changes with the database within a transaction.
