Best practices for complex transaction processing with JDBC, Hibernate and MyBatis
Article Introduction:In complex transaction processing, the best ORM framework choice depends on the project requirements. JDBC provides maximum flexibility, but the risk is higher. Hibernate manages transactions through sessions, providing optimizations in lazy loading and locking. MyBatis enables flexible transaction definition through SQL configuration and mapping. Practical cases show code examples for using Hibernate and MyBatis to manage complex transactions, including best practices such as explicitly declaring transaction boundaries, using sessions and transaction factories, and handling lazy loading and locking.

How does Java exception handling relate to transaction processing?
Article Introduction:Exception handling is used to handle application errors, while transaction handling ensures that the operation as a whole succeeds or fails. When an exception is thrown within a transaction, the transaction is automatically rolled back. Therefore, it is crucial to have exception handling in transactional operations to maintain data integrity, e.g. catching exceptions and rolling back or committing the transaction depending on the error type.

What is the SpringBoot transaction processing mechanism?
Article Introduction:1. Spring's transaction mechanism All data access technologies have transaction processing mechanisms. These technologies provide APIs to start transactions, submit transactions to complete data operations, or roll back data when an error occurs. Spring's transaction mechanism uses a unified mechanism to handle transaction processing of different data access technologies. Spring's transaction mechanism provides a PlatformTransactionManager interface. Transactions with different data access technologies use different interface implementations: The code to define the transaction manager in the program is as follows: @BeanpublicPlatformTransactionManagertransactionManager
