如何获取新文件的名称和路径
下午好。我需要确保单击按钮时会创建一个新的 Excel 文件。我已经有了这个函数并且一切正常，但是..路径和文件名写在函数本身中，我需要确保路径和文件名是由用户选择的。怎么做呢？
仅允许您从现有文件中进行选择。我需要准确获取新文件的路径和名称。
我的功能
@SneakyThrows
@GetMapping("/Exel")
@ResponseBody
public void updateNotFullPay(){
Integer year = 2022;
List<DescriptionMotion> description = descriptionMotionService.findMoveByAllBranchAndYear(year);
String file = "C:\\Users\\Elina-AA-int\\exe.xlsx";
XSSFWorkbook book = new XSSFWorkbook();
XSSFSheet sheet = book.createSheet("ОК (ООТиЗ)");
.......
//code//
}
我的输入和链接我不知道该怎么做
<input type="file">
<a type="button" class="btn btn-primary btn-sm" th:href="@{/report/Exel}">Создать Exel-файл за текущий год</a>
Good afternoon. I need to make sure that when a button is clicked, a new Excel file is created. I already have this function and everything works, but .. The path and file name are written IN the function itself, and I need to make sure that the path and file name are chosen by the user. How to do it?
<input type="file"> only allows you to select from existing files. And I need to get exactly the path and name for the NEW file.
