# Baseline: sw-business-bank 银行代扣文件传输配置能力

## 固定基线

- 记录日期：2026-03-24
- `water-backend` 分支：`develop`
- `water-backend` 提交：`b540f1f48bf2d6c28aa183749ca61231071c0942`

## 核心代码落点

- `sw-business-bank-api/src/main/java/cn/com/emsoft/sw/bankbusiness/enums/ApiTypeEnum.java`
- `sw-business-bank-server/src/main/java/cn/com/emsoft/sw/bankbusiness/dal/dataobject/channelapiconfig/ChannelApiConfigExtParams.java`

- `sw-business-bank-server/src/test/java/cn/com/emsoft/sw/bankbusiness/service/bankwithholding/BankWithholdingTransferConfigTest.java`

## 固定结论

- 本轮实现将 `BankWithholdingServiceImpl` 的硬编码送盘、回盘、对账目录切换为统一解析器输出。
- 默认规则继续由 Spring profile + Nacos 承接；覆盖规则通过 `bk_channel_api_config` 的 `apiType=FILE_TRANSFER_CONFIG` + `extParams` 承接。
- 已落库批次的回盘目录与协议在送盘创建时固化到批次对象，后续配置切换不回溯修改旧批次。
