以下是发送电子邮件的代码：
@RequestMapping(value = "/exportMailMDP", method = RequestMethod.POST)
public ModelAndView exportMailMDP(HttpServletRequest request, HttpSession session, @RequestParam String login,
@RequestParam String question, @RequestParam String reponse) {
ModelAndView modelView = new ModelAndView("redirect:/");
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "465");
if (utilisateurDao.verifierLoginUser(login)) {
Utilisateur utilisateur = utilisateurDao.verifierQuestionReponse(login, question, reponse);
if (utilisateur != null) {
modelView.addObject("es", "4");
final String username = "sse.notif@gmail.com";
final String password = "@mbre2017";
String to = utilisateur.getEmail();
String messageNewPassword = "Votre nouveau mot de passe est 1";
Session sessionMail = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(sessionMail);
message.setFrom(new InternetAddress(username));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));
message.setSubject("Initialisation mot de passe de : " + utilisateur.getLogin());
message.setText(messageNewPassword);
Transport.send(message); // it causes the bug
} catch (MessagingException e) {
e.printStackTrace();
modelView.addObject("es", "serveurMail");
}
} else {
modelView.addObject("es", "3");
}
} else {
modelView.addObject("es", "2");
}
return modelView;
}
那有什么不对？

您需要添加javax.mail api的实现。
根据https://javaee.github.io/javamail/，以下可能是一种解决方案。
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.1</version>
</dependency>
答案 1 :(得分：1)
将mail.jar（可能还有activation.jar）添加到pom.xml依赖项中。
从这里开始：http://www.oracle.com/technetwork/java/notes-2-149762.txt：
JavaMail API jar文件＆＃34; mail.jar＆＃34;包括完整的JavaMail API 实现和所有 Sun协议提供程序 - IMAP，SMTP和 POP3。使用JavaMail API最简单的方法就是使用 mail.jar文件并忽略此包中的其他jar文件。
在某些情况下，可能需要最小化JavaMail的大小 应用程序使用的API代码（例如，使用applet下载时）。 在这种情况下，您可能希望包含＆＃34; mailapi.jar＆＃34;文件，哪个 包括 no 协议提供程序，以及只有jar文件 你需要的协议提供者。例如，一个只需要的applet 发送邮件可以使用＆＃34; mailapi.jar＆＃34;文件和＆＃34; smtp.jar＆＃34;文件。
