MultipartFile#getBytes We can use this method to write the bytes to a file: MultipartFile multipartFile = new MockMultipartFile("sourceFile. tmp", "Hello World". getBytes()); File file = new File("src/main/resources/targetFile.
public interface MultipartFile extends InputStreamSource. A representation of an uploaded file received in a multipart request. The file contents are either stored in memory or temporarily on disk. In either case, the user is responsible for copying file contents to a session-level or persistent store as and if desired ...
Multipart requests combine one or more sets of data into a single body, separated by boundaries. You typically use these requests for file uploads and for transferring data of several types in a single request (for example, a file along with a JSON object).
You can get the content of a MultipartFile by using the getBytes method and you can write to the file using Files.newOutputStream():
public void write(MultipartFile file, Path dir) { Path filepath = Paths.get(dir.toString(), file.getOriginalFilename()); try (OutputStream os = Files.newOutputStream(filepath)) { os.write(file.getBytes()); } } You can also use the transferTo method:
public void multipartFileToFile( MultipartFile multipart, Path dir ) throws IOException { Path filepath = Paths.get(dir.toString(), multipart.getOriginalFilename()); multipart.transferTo(filepath); } If you love us?
