接口接收文件
@RequestParam("file") MultipartFile file

MultipartFile转byte[]

String name = file.getName();
String originalFilename = file.getOriginalFilename();
String contentType = file.getContentType();
String bytes = file.getBytes();

byte[]转MultipartFile

InputStream inputStream = new ByteArrayInputStream(bytes);
MultipartFile file = new MockMultipartFile(name, originalFilename, contentType, inputStream);
