我會通過彈簧mvc發送電子郵件，但我得到下面的錯誤。爲什麼不能通過彈簧發送電子郵件mvc
感謝您的幫助。
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)
我的代碼是：
public class EmailMessage
{
private String receiverEmailAddress;
private String subject;
private String messageBody;
public EmailMessage()
{
}
//+setters and getters
}
這是服務CALSS
@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);
}
}
而且控制器：
@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";
}
}
}
JSP頁面是：

和mail.properties

這裏是服務類：
public class MailService implements MailRepository
{

public void setMailSender(JavaMailSender mailSender)

{

message.setFrom(mailFrom);
message.setTo(mailTo);
message.setText(mailFrom + mailTo + mailBody);
this.mailSender.send(message);

public void sendEmail(EmailMessage emailMessage)
{

// sending the message
this.mailSender.send(message);
}

};
try
{
this.mailSender.send((SimpleMailMessage) preparator);
}
catch (Exception ex)
{
ex.printStackTrace();
return false;

return true;

}
謝謝
嗨 我也編輯我的問題。 它不工作我得到了一個404.I用戶MailService類，正如你所看到的，我有幾種發送電子郵件的方法，但其中沒有一個正在工作。 – user1067665
您的@RequestMapping缺少一個斜槓，它應該是「/ sendPassword」。 – izilotti
但這不是問題。任何人都可以幫助 – user1067665
