java - 如何在 Spring 中显示下载文件名中的非法字符？

Question

我下载的文件名为 Ça_r_lar_02_07_2019_12_09.xlsx，但是，我想要它 Çağrılar_02_07_2019_12_09.xlsx。我该如何解决？

try (Workbook workbook = new XSSFWorkbook()) {
                new XlsExporter().exportXls(workbook, grh);
                SimpleDateFormat sdf = new SimpleDateFormat("_dd_MM_yyyy_HH_mm");
                String name = grh.getReportName() + sdf.format(new Date());
                response.setContentType(MediaType.APPLICATION_OCTET_STREAM.getType());
                response.setHeader(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + name +  ".xlsx\"");
                workbook.write(response.getOutputStream());
                response.getOutputStream().flush();
            }

在发送响应之前尝试对您的文件名进行 UTF-8 编码

try (Workbook workbook = new XSSFWorkbook()) {
                new XlsExporter().exportXls(workbook, grh);
                SimpleDateFormat sdf = new SimpleDateFormat("_dd_MM_yyyy_HH_mm");
                String name = grh.getReportName() + sdf.format(new Date());
                name = URLEncoder.encode(name,"UTF-8"); 
                response.setContentType(MediaType.APPLICATION_OCTET_STREAM.getType());
                response.setHeader(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + name +  ".xlsx\"");
                workbook.write(response.getOutputStream());
                response.getOutputStream().flush();
            }
