#RequestMapping(value = "/upload", method = RequestMethod.POST)
public void uploadFileHandler(#RequestParam("name") String name,
#RequestParam("name") MultipartFile file) {
if (!file.isEmpty()) {
try {
byte[] bytes = file.getBytes();
// Creating the directory to store file
//String rootPath = System.getProperty("catalina.home");
String rootPath = "C:\\Desktop\\uploads";
File dir = new File(rootPath + File.separator + "tmpFiles");
if (!dir.exists())
dir.mkdirs();
// Create the file on server
File serverFile = new File(dir.getAbsolutePath()
+ File.separator + name);
BufferedOutputStream stream = new BufferedOutputStream(
new FileOutputStream(serverFile));
stream.write(bytes);
stream.close();
System.out.println("Server File Location="
+ serverFile.getAbsolutePath());
System.out.println("You successfully uploaded file=" + name);
} catch (Exception e) {
System.out.println("You failed to upload " + name + " => " + e.getMessage());
}
} else {
System.out.println("You failed to upload " + name
+ " because the file was empty.");
}
}

You should have a thing like this:
#RequestMapping(value = "/upload", method = RequestMethod.POST, consumes = "multipart/form-data")
public void uploadFileHandler(#RequestParam("name") String name,
#RequestParam("file") MultipartFile file) {
if (!file.isEmpty()) {
try {
byte[] bytes = file.getBytes();
// Creating the directory to store file
//String rootPath = System.getProperty("catalina.home");
String rootPath = "C:\\Users\\mworkman02\\Desktop\\uploads";
File dir = new File(rootPath + File.separator + "tmpFiles");
if (!dir.exists())
dir.mkdirs();
// Create the file on server
File serverFile = new File(dir.getAbsolutePath()
+ File.separator + name);
BufferedOutputStream stream = new BufferedOutputStream(
new FileOutputStream(serverFile));
stream.write(bytes);
stream.close();
System.out.println("Server File Location="
+ serverFile.getAbsolutePath());
System.out.println("You successfully uploaded file=" + name);
} catch (Exception e) {
System.out.println("You failed to upload " + name + " => " + e.getMessage());
}
} else {
System.out.println("You failed to upload " + name
+ " because the file was empty.");
}
}
Please pay attention to consumes = "multipart/form-data". It is necessary for your uploaded file because you should have a multipart call. You should have #RequestParam("file") MultipartFile file instead of #RequestParam("name") MultipartFile file).
Of course you should have configured a multipartview resolver the built-in support for apache-commons file upload and native servlet 3.
