dbVisitor includes a lightweight local transaction manager that supports all 7 transaction propagation behaviors and 5 isolation levels. You can control transactions in three ways; the specific choice depends on your project requirements.

Usage Guide

Concepts

• Local Transaction Manager: understand how the dbVisitor transaction manager works and the transaction stack mechanism.
• Propagation Behavior: understand the differences and applicable scenarios of the 7 propagation behaviors.
• Isolation Levels: understand how different isolation levels affect concurrent reads and writes.

How to use

• Programmatic Transactions: manually call begin/commit/rollBack to control transactions — flexible but more verbose.
• Transaction Template: execute transaction code blocks via TransactionTemplate, with automatic commit/rollback handling.
• Annotation-based Transactions: declaratively control transactions via @Transactional annotations — the most concise code.
