#16 Hibernate Tutorial in Hindi | One-to-One Mapping | @JoinColumn, Cascade, FetchType Explained

Welcome back to CodeHunt’s Hibernate–JPA Tutorial Series! In this session, we begin Hibernate Mapping – Part 1, where we focus on one of the most powerful and commonly used relationships in Hibernate — One-to-One Mapping. We cover everything from basic concepts to real project usage, including unidirectional and bidirectional mapping, @JoinColumn, cascading, and fetch types. This video is designed to give you complete clarity with diagrams and practical examples. 🎯 What You’ll Learn in This Video ✅ 1. One-to-One Mapping Basics What is one-to-one mapping? Why one-to-one is used in real-world systems ✅ 2. Unidirectional One-to-One Mapping How mapping works in one direction How Hibernate creates and manages the foreign key Understanding ownership of relationship Code explanation + table diagram ✅ 3. Bidirectional One-to-One Mapping What changes when both classes refer to each other Who owns the relationship in bidirectional mapping? ✅ 4. @JoinColumn Explained What is @JoinColumn? Why it is required in one-to-one mapping How foreign keys are created ✅ 5. Cascading in One-to-One What is cascading in Hibernate? Types of cascading: PERSIST MERGE REMOVE REFRESH DETACH ALL When to use cascading in real applications ✅ 6. FetchType: LAZY vs EAGER Difference between lazy and eager fetching Default fetch type for One-to-One Performance impact in large applications Real examples: When to prefer LAZY? When to avoid EAGER? 🧠 By the End of This Session, You Will Clearly Understand: How to implement one-to-one mapping properly Difference between unidirectional and bidirectional How @JoinColumn controls foreign key generation How cascading works in one-to-one mapping How LAZY and EAGER fetching affect performance Interview-level clarity on Hibernate relationships 👨‍💻 Perfect For: Students | Java Developers | Hibernate Beginners | Backend Engineers | Framework Learners | Interview Preparation 📩 Contact for Enrollment: 📞 Call / WhatsApp: 8088467640 📌 Watch the Hibernate 2.0 Series Here: 👉 🔗    • Hibernate JPA | Gamma Batch Live🔊   #java #corejava #codehunt #saifsir #javaprogramming #java8 #javatutorial #hibernate
