springboot excel导入导出代码

你好，关于springboot excel导入导出代码，我可以为您提供一些参考。您可以使用Apache POI库来实现Excel文件的读写操作，具体可以参考以下代码：

1. 导入Excel文件

@PostMapping("/import")
public String importExcel(@RequestParam("file") MultipartFile file) throws Exception {
    Workbook workbook = WorkbookFactory.create(file.getInputStream());
    Sheet sheet = workbook.getSheetAt();
    for (Row row : sheet) {
        for (Cell cell : row) {
            // 处理单元格数据
        }
    }
    return "success";
}

2. 导出Excel文件

@GetMapping("/export")
public void exportExcel(HttpServletResponse response) throws Exception {
    Workbook workbook = new XSSFWorkbook();
    Sheet sheet = workbook.createSheet("Sheet1");
    Row row = sheet.createRow();
    Cell cell = row.createCell();
    cell.setCellValue("Hello World");
    response.setContentType("application/vnd.ms-excel");
    response.setHeader("Content-Disposition", "attachment;filename=test.xlsx");
    workbook.write(response.getOutputStream());
}

希望这些代码可以帮助到您。
