Spring
コントローラーで次の例外が発生します。
Bean クラス [org.springframework.validation.BindingResult] をインスタンス化できませんでした: 指定されたクラスはインターフェースです。
これが私のコントローラーです:
@Controller
public class SendPasswordController {
@Resource
private JavaMailSender mailSender;
//@Autowired
//private UserService userService;
@Resource
private UserService userService;
@Resource
private ChangePasswordService changePasswordService;
@Resource
private EmailSenderService emailSenderService;
@RequestMapping(value = "/EmailForm" ,method= RequestMethod.GET)
public ModelAndView sendEmail(@ModelAttribute(value="emailPasswordForm")
BindingResult result,HttpServletRequest request){
ModelAndView mav = new ModelAndView("EmailForm");
String userName= null;
String password=null;
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
if (!(auth instanceof AnonymousAuthenticationToken)) {
UserDetails userDetails =(UserDetails)auth.getPrincipal();
userName=userDetails.getUsername();
password=userDetails.getPassword();
UserForm userForm = userService.getUser(userName);
System.out.println("name is"+userName);
System.out.println("password is"+password);
User user=changePasswordService.findByNameAndPassword(userName, password);
if(user!=null){
final String emailTo =user.getUserEmail();
final String subject = "Password Reset";
final String passwordGenerated = changePasswordService.randomPasswordGenerate();
// for logging
System.out.println("emailTo: " + emailTo);
System.out.println("subject: " + subject);
System.out.println("message: " + passwordGenerated);
//System.out.println("attachFile: " + attachFile.getOriginalFilename());
//emailService.sendEmail(user, passwordGenerated);
mailSender.send(new MimeMessagePreparator() {
@Override
public void prepare(MimeMessage mimeMessage) throws Exception {
MimeMessageHelper messageHelper = new MimeMessageHelper(
mimeMessage, true, "UTF-8");
messageHelper.setTo(emailTo);
messageHelper.setSubject(subject);
messageHelper.setText(passwordGenerated);
}
});
emailSenderService.updatePassword(user, passwordGenerated);
Authentication authentication = new UsernamePasswordAuthenticationToken(user, user.getPassWord());
SecurityContextHolder.getContext().setAuthentication(authentication);
return new ModelAndView("Result");
}
}
return mav;
}
}
