如何更改保存文件目录？

Question

我想更改保存文件目录。 这是我的代码：

@RequestMapping(value = "/UploadFile")
public String uploadFile(HttpServletResponse response String base64, String name, String size) throws Exception {
    byte[] decodedFile = Base64.getDecoder().decode(base64.getBytes(StandardCharsets.UTF_8));
    response.setContentType("application/octet-stream");
    response.setHeader("Content-Disposition", "attachment; filename=" + name);
    response.setHeader("Pragma", "no-cache");
    response.setHeader("Cache-Control", "no-cache");

    InputStream is = new ByteArrayInputStream(decodedFile);
    IOUtils.copy(is, response.getOutputStream());
    response.flushBuffer();
    return "true";
}

试试这个：

 File path = new File("YOUR PATH HERE") ;
            try (FileOutputStream fos = new FileOutputStream(path)) {
                fos.write(decodedFile);
            } catch (IOException e) {
                e.printStackTrace();
            }

如果字符串名称是原始文件名，您也可以这样做：

File path = new File("C:\\YOUR_PATH\\images\\" + name);
