Spring Boot Transactions & Propagation | @Transactional, ACID Properties, Rollback Management

Описание: Master Database Integrity and Transaction Management in Spring Boot 3! In this tutorial, we move beyond simple database saves to build a robust, fail-safe persistence layer using the `@Transactional` annotation.

We dive deep into how Spring manages database state. You'll learn the core concepts of ACID properties and how Spring’s declarative transaction management ensures that your data remains consistent, even when errors occur. We take it a step further by exploring Transaction Propagation and Isolation levels to handle complex, multi-service business logic.

What you will learn in this video:
✅ How to use @Transactional to ensure data consistency (ACID).
✅ Understanding Transaction Propagation (REQUIRED vs. REQUIRES_NEW).
✅ Managing Rollback Rules: How to handle Checked vs. Unchecked exceptions.
✅ Common Pitfalls: Why Self-Invocation (Internal calls) breaks your transactions.
✅ How to configure Isolation Levels to prevent Dirty Reads and Phantom Reads.
✅ Using Read-Only transactions to optimize database performance.

Whether you're building a financial system or a simple CRUD app, mastering transactions is essential for preventing data corruption in production-ready Spring Boot applications.
