PaymentTransactionMapper

Info

MyBatis mapper interface for payment transaction persistence.

Overview

PaymentTransactionMapper provides a single insertIgnore method for inserting payment transaction records. The INSERT IGNORE semantics ensure that duplicate transaction records from repeated payment provider notifications are silently skipped.

Methods

Method	Return Type	Description
insertIgnore(tx)	int	Insert a transaction record, ignoring duplicates

Parameters

Param	Type	Description
tx	PaymentTransaction	Transaction entity to insert

Tips

The INSERT IGNORE pattern is critical for idempotent payment processing — the same transaction may be notified multiple times by the payment provider.
