public class hello {
    public static void main(String[] args) {
        String to = "111111qq.com";
        String from = "111111@qq.com";
        String host = "smtp.qq.com";
        Properties properties = System.getProperties();
        properties.setProperty("mail.smtp.host",host);
        properties.put("mail.smtp.auth","true");


        Session session = Session.getDefaultInstance(properties, new Authenticator() {
            public PasswordAuthentication getPasswordAuthentication()
            {
　　　　　　　　　　//账户，邮箱授权码
                return new PasswordAuthentication("111111","6666ufrtmxibjgf");

        });

        try {
            MimeMessage mimeMessage = new MimeMessage(session);
            mimeMessage.setFrom(new InternetAddress(from));
            mimeMessage.addRecipient(Message.RecipientType.TO,
                    new InternetAddress(to));
