file not binding to angularjs service using FormData - angularjs

Question

I am trying to upload a file using angularjs and spring 3, I have written a service which is not binding the selected file. I don't know what mistake I have been doing, please help me to solve this problem. I am using commonsmultipart for uploading the files. following are the fileUploadService and controller codes.
MyApp.service('fileUploadService', function ($http, $q) {
this.uploadFileToUrl = function (file, uploadUrl, formData) {
//FormData, object of key/value pair for form fields and values
var fileFormData = new FormData();
fileFormData.append('fileUpload', file);
// console.log(formData);
fileFormData.append('name', formData.name);
fileFormData.append('email', formData.email);
fileFormData.append('password', formData.password);
fileFormData.append('mobile_no', formData.mobile_no);
fileFormData.append('register-submit', 'Register Now');
var deffered = $q.defer();
$http.post(uploadUrl, fileFormData, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
}).success(function (response) {
deffered.resolve(response);
}).error(function (response) {
deffered.reject(response);
});
return deffered.promise;
}
});
Spring Controller:
#SuppressWarnings({ "unused", "static-access" })
#RequestMapping( value="/RegisterCandidate" , method = RequestMethod.POST)
private String RegisterCandidate(HttpServletRequest request,
HttpServletResponse response,
#RequestParam CommonsMultipartFile[] fileUpload ) throws Exception{
System.out.println("In method");
String email = request.getParameter("email");
System.out.println("email==============="+email);
String Password = request.getParameter("password");
String usr_name = request.getParameter("name");
String mobile_no = request.getParameter("mobile_no");
Date dateentry = new Date();
java.sql.Timestamp entry_date = new Timestamp(dateentry.getTime());
Users_Pojo usr = new Users_Pojo();
if (fileUpload != null && fileUpload.length > 0) {
for (CommonsMultipartFile aFile : fileUpload){
usr.setFilename(aFile.getOriginalFilename());
usr.setFile_data(aFile.getBytes());
System.out.println("aFile.getBytes()======"+aFile.getBytes());
System.out.println("aFile.getInputStream()======"+aFile.getInputStream());
System.out.println("aFile.getStorageDescription()======"+aFile.getStorageDescription());
System.out.println("aFile.getSize();======"+aFile.getSize());
System.out.println("aFile.getContentType();==="+aFile.getContentType());/* */
}
}
MD5CodeGenerator md5 = new MD5CodeGenerator();
usr.setUc_password(md5.convertToMD5(Password));
usr.setUc_name(email);
usr.setUc_contact_person(email);
usr.setUc_phone_no(BigInteger.valueOf(Long.parseLong(mobile_no)));
usr.setUc_email_id(email);
usr.setUc_type_id(1);
usr.setUc_active(1);
usr.setValid_from(null);
usr.setValid_to(null);
usr.setDesignation("jobseekar");
usr.setIp_address("164.100.19.79");
usr.setUser_location(1);
usr.setEntry_date(entry_date);
scm_service.save(usr, email);
return "success";
