- 所有 Excel 批量导入功能如果存在部分数据无法导入、校验失败或处理异常,后端必须将导入失败的数据导出为 Excel 文件返回给前端下载。
|
||||
- 导入失败 Excel 的字段顺序必须与原导入模板保持一致,并在最后一列追加“导入失败原因”;失败原因应包含明确行号和可读错误信息。
|
||||
- 导入失败 Excel 中的失败数据行必须使用红色文字展示,最后一列“导入失败原因”的错误信息也必须使用红色文字展示;表头可保持默认样式。
|
||||
- 导入失败 Excel 中仅出错字段/列对应的单元格使用红色文字展示,最后一列“导入失败原因”的错误信息也必须使用红色文字展示;不得将整行失败数据全部标红,表头可保持默认样式。
|
||||
- 失败原因应尽量包含原导入模板中的列名,便于通用导出工具准确定位并标红对应错误单元格;无法定位具体字段的业务错误,仅标红“导入失败原因”列。
|
||||
- 导入模板本身不得包含失败原因列;如复用导入模型,应使用 `@ExcelIgnore` 忽略内部错误字段,或单独定义 `XxxImportFailureExcel` 模型。
|
||||
- 导入逻辑应逐行处理:可成功导入的数据正常保存,失败行收集到失败明细;除非业务明确要求全量事务回滚,不得因部分失败回滚已成功行。
|
||||
- Controller 在失败明细非空时应直接通过导入失败明细通用导出工具写入 `HttpServletResponse`,文件名统一包含业务名称、`导入失败明细` 和时间戳;全部成功时返回标准 `R.success`。
