PaymentDlqLogMapper

Info

MyBatis mapper interface for dead-letter queue log persistence and querying.

Overview

PaymentDlqLogMapper provides methods for inserting DLQ log records and querying them for admin review. It supports filtering by notification ID, order number, and trade state (to distinguish payment DLQ from receipt DLQ entries).

Methods

Method	Return Type	Description
insert(logItem)	int	Insert a DLQ log record
adminList(notifyId, outTradeNo, limit)	List<PaymentDlqLog>	Query DLQ logs with optional filters
adminListByTradeState(notifyId, outTradeNo, tradeState, limit)	List<PaymentDlqLog>	Query DLQ logs filtered by trade state

Parameters

adminList

Param	Type	Description
notifyId	String	Optional notification ID filter (nullable)
outTradeNo	String	Optional order number filter (nullable)
limit	int	Maximum results (1-200)

adminListByTradeState

Param	Type	Description
notifyId	String	Optional notification ID filter (nullable)
outTradeNo	String	Optional order number filter (nullable)
tradeState	String	Trade state filter (e.g. RECEIPT_EMAIL)
limit	int	Maximum results (1-200)

Tips

Use adminListByTradeState with tradeState = "RECEIPT_EMAIL" to query receipt email dispatch failures separately from payment notification failures.
