                if(file!=null) {
                    String path="E:/springUpload"+"/"+file.getOriginalFilename();
                    //upload
                    file.transferTo(new File(path));
                }
            }
        }
        System.out.println(name);
        return "/success";
    }
}

Save the file to the springUpload folder under the E drive
