Hibernate Masterclass | Session 6 — save, update, delete, get vs load, Object States & Lazy Loading
Welcome to Session 6 of the Hibernate Masterclass — an in-depth, hands-on session where we learn how Hibernate works internally when saving, updating, deleting, and fetching data from the database.
In this session, we build further on real-time Hibernate concepts and explore how entities behave in different states. You will understand what happens behind the scenes when an object moves from transient → persistent → detached state and how Hibernate manages changes automatically in persistent state.
We also compare the get() and load() methods, understand lazy loading vs early (eager) loading, and see how session operations affect entity lifecycle and queries.
Additionally, this session covers four different approaches to create a Hibernate + Servlet integrated project, giving you clarity on structuring enterprise-level Java applications.
🧠 In this lecture, you’ll learn:
✅ save(), update(), delete() — How they work internally
✅ How to fetch data (important session methods)
✅ Difference between get() and load()
✅ Lazy Loading vs Early/Eager Loading
✅ Entity Lifecycle: Transient, Persistent, Detached State
✅ What happens if you modify a persistent object?
✅ 4 Ways to Create a Hibernate + Servlet Integration Project
…and more real-time Hibernate concepts!
🎯 By the end of this session
You will confidently understand how Hibernate performs CRUD operations at the ORM level, how it manages objects based on their states, and how loading strategies impact performance.
You will also be ready to integrate Hibernate with Servlets using different project structures.
