    try {
      Properties propsMail = Resources.getResourceAsProperties("jdbc.properties");
      String host = propsMail.getProperty("mailHost");

      final String user = propsMail.getProperty("mailUserName");// 用户名
      final String pwd = propsMail.getProperty("mailUserPass");// 密码
      /* * Session类定义了一个基本的邮件对话。 */
      Session session = Session.getInstance(props, new Authenticator() {

      /* * Transport类用来发送邮件。 传入参数smtp，transport将自动按照smtp协议发送邮件。 */

      /* * Message对象用来储存实际发送的电子邮件信息 */
      MimeMessage message = new MimeMessage(session);

      message.addRecipients(Message.RecipientType.TO,
          new InternetAddress[] { new InternetAddress(ToAdress, Toname), });
      message.saveChanges();

      // 设置邮件内容及编码格式
      // 后一个参数能够不指定编码，如"text/plain"，可是将不能显示中文字符
      message.setContent(content, "text/html;charset=utf-8");
      Transport.send(message);

      transport.close();
      sendStatic = MailStatus.SUCCESS.getTitle();
