严重度：🟠 HIGH

Selector 控制器中 .map(t -> xxxService.findById(t)) 对每个 ID 单独查询，1000 个 ID = 1000 次 DB。

受影响：

  • BaseDataSelectorController — 12 处（product/brand/category/member/store/supplier/customer/shop/address/payType/logistics 等）
  • ScSelectorController:275
  • SettleSelectorController:84,125

修复： 使用批量查询方法（如 findByIds），一次性获取全部数据后再做 map
