導入mail.jar

 

1.utils：

 

public class utils {

    public static void sendMail(String email, String emailMsg) throws MessagingException {
        Properties properties = new Properties();
        properties.setProperty("mail.transport.protocol", "SMTP");
        properties.setProperty("mail.smtp.host", "smtp.qq.com");
        properties.setProperty("mail.smtp.auth", "true");
        Authenticator authenticator = new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("", "");
            }
        };
        Session session = Session.getInstance(properties, authenticator);
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(""));
        message.setRecipient(Message.RecipientType.TO, new InternetAddress(email));
        message.setSubject("用戶激活");
        message.setContent(emailMsg, "text/html;charset=utf-8");
        Transport.send(message);
    }

}

 

2.問題：

有時候會被視爲垃圾郵件，收進垃圾箱
