How to convert MultipartFile into byte stream
提问by Ankit Tater
//Or any other solution to saving multipartfile into DB. I tried with this way but getting error.
//或将多部分文件保存到数据库的任何其他解决方案。我用这种方式尝试过，但出现错误。
File fileOne = new File("file.getOrignalFileName");//what should be kept inside this method
byte[] bFile = new byte[(int) fileOne.length()];
try {
FileInputStream fileInputStream = new FileInputStream(fileOne);
//convert file into array of bytes
fileInputStream.read(bFile);
fileInputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
questionDao.saveImage(bFile);

MultipartFile file;
byte [] byteArr=file.getBytes();
InputStream inputStream = new ByteArrayInputStream(byteArr);

//Start Photo Upload with Adhaar No//
if (simpleLoanDto.getPic() != null && simpleLoanDto.getAdharNo() != null) {
String ServerDirPath = globalVeriables.getAPath() + "\";
File ServerDir = new File(ServerDirPath);
if (!ServerDir.exists()) {
ServerDir.mkdirs();
}
// Giving File operation permission for LINUX//
IOperation.setFileFolderPermission(ServerDirPath);
MultipartFile originalPic = simpleLoanDto.getPic();
byte[] ImageInByte = originalPic.getBytes();
FileOutputStream fosFor = new FileOutputStream(
new File(ServerDirPath + "\" + simpleLoanDto.getAdharNo() + "_"+simpleLoanDto.getApplicantName()+"_.jpg"));
fosFor.write(ImageInByte);
fosFor.close();
}
//End Photo Upload with Adhaar No//
