Transaction management is a fundamental aspect of any application that interacts with a database. It ensures data integrity and consistency by controlling the commit and rollback of transactions. In this article, we will delve into transaction management in Spring Boot, providing both technical and layman's explanations, along with real-world code examples and a deep dive into its internal workings.
What is Transaction Management?
- Layman Explanation: Imagine you're at a bank and you want to transfer money from your account to a friend's account. You wouldn't want the money to be deducted from your account but not added to your friend's account due to some error. Transaction management ensures that both actions are completed successfully or don't happen at all, keeping everything consistent.
- Technical Explanation: Transaction management in a database context ensures that a series of operations are executed in a way that maintains data integrity. This means all operations within a transaction must either complete successfully (commit) or have no effect at all (rollback).
Spring Boot and Transaction Management
Spring Boot provides comprehensive transaction management support, allowing developers to manage transactions declaratively using annotations or programmatically using the PlatformTransactionManager.
Declarative Transaction Management
The most common way to manage transactions in Spring Boot is through annotations, which provide a declarative approach.
