The constructor BufferedOutputStream(FileOutputStream) is undefined
the method is:
@RequestMapping(value="/upload", method=RequestMethod.POST)
public @ResponseBody ResponseEntity<String> handleFileUpload(@RequestParam("name") String name,
@RequestParam("file") MultipartFile file) throws Exception{
if (name.contains("/")) {
return ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body("Folder separators not allowed.");
} else if (name.contains("/")) {
return ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body("Relative pathnames not allowed.");
} else if (!name.endsWith(".jar")) {
return ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body("File type not allowed. Must be a Jar file type ending in '.jar'.");
}
if (!file.isEmpty()) {
try {
byte[] bytes = file.getBytes();
BufferedOutputStream stream = new BufferedOutputStream(new FileOutputStream(new File(name)));
stream.write(bytes);
stream.close();
return ResponseEntity.ok("File " + name + " uploaded.");
} catch (Exception e) {
return ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body(e.getMessage());
}
} else {
return ResponseEntity.status(HttpStatus.UNPROCESSABLE_ENTITY).body("You failed to upload " + name + " because the file was empty.");
}
}
}
i get error in this line:
BufferedOutputStream stream = new BufferedOutputStream(new FileOutputStream(new File(name)));
The only reason I can think of is, you have imported a different class than following
import java.io.BufferedOutputStream;
