spring mvc でメールを送信しますが、以下のエラーが表示されます。
私が得ることができるすべての助けに感謝します。
java.lang.ClassCastException: service.MailService$1 cannot be cast to org.springframework.mail.SimpleMailMessage
at service.MailService.sendEmail(MailService.java:69)
at sendPasswordToUser(SendPasswordController.java:44)
私のコードは次のとおりです。
public class EmailMessage
{
private String receiverEmailAddress;
private String subject;
private String messageBody;
public EmailMessage()
{
}
//+setters and getters
}
これがサービスコールです
@Service
public class EmailSenderService implements EmailSenderRepository
{
private MailSender mailSender;
private SimpleMailMessage mailMessage;
public void setMailMessage(SimpleMailMessage mailMessage) {
this.mailMessage = mailMessage;
}
public void setMailSender(MailSender mailSender) {
this.mailSender = mailSender;
}
public void sendEmail(EmailMessage emailMessage)
{
SimpleMailMessage message = new SimpleMailMessage(this.mailMessage);
message.setTo(emailMessage.getReceiverEmailAddress());
message.setSubject(emailMessage.getSubject());
message.setText(emailMessage.getMessageBody());
//sending the message
mailSender.send(message);
}
}
そしてコントローラー：
@Controller
@RequestMapping
public class SendPasswordController
{
@Autowired
private static UserService us = new UserService();
@Autowired
private static MailService mailService = new MailService();
@RequestMapping(value = "/getPassword", method = RequestMethod.GET)
public String showForm()
{
return "index";
}
@RequestMapping(value = "sendPassword", method = RequestMethod.POST)
public String sendPasswordToUser(@RequestParam("email") String email, ModelMap model, HttpServletRequest req, HttpServletResponse response)
{
String subject = "Sending your password to you ";
User user = us.findUserByAnyParameter(email);
if (email.equals(user.getEmail()))
{
mailService.sendEmail(user.getPassword(), subject, email);
model.addAttribute("message", user);
return "confirmNewPassword";
}
else
{
return "redirect:/index";
}
}
}
