    public static void main(String[] args) throws Exception {
        SendMailAddFile send = new SendMailAddFile();
        send.sendFile();

    public void sendFile() throws Exception {
        Properties prop = new Properties();
        prop.setProperty("mail.smtp.host","smtp.sina.com");
        prop.setProperty("mail.smtp.auth","true");
        MyAuthenticator authenticator = new MyAuthenticator();
        Session session = Session.getInstance(prop,authenticator);
        MimeMessage message = new MimeMessage(session);
        Address from = new InternetAddress("[e-mail]"); //你的邮箱
        Address to = new InternetAddress("要发送的Email");   //她的邮箱
        message.setFrom(from);
        message.setRecipient(Message.RecipientType.TO,to);
        message.setSubject("o(∩_∩)o...哈哈");
        Multipart mpart = new MimeMultipart();
        MimeBodyPart body = new MimeBodyPart();
        body.setText("测试带附件的邮件发送情况");
        mpart.addBodyPart(body);
        body = new MimeBodyPart();
        DataSource ds = new FileDataSource("c://1.jpg");
        DataHandler dh = new DataHandler(ds);
