  // 1.创建一个程序与邮件服务器对话对象 Session

  Properties props = new Properties();
  //设置发送的协议
  //props.setProperty("mail.transport.protocol", "SMTP");
  
  //设置发送邮件的服务器
  //props.setProperty("mail.host", "smtp.126.com");
  //props.setProperty("mail.smtp.auth", "true");//指定验证为true

  //创建验证器
  Authenticator auth = new Authenticator() {
   public PasswordAuthentication getPasswordAuthentication() {
    //设置发件人的账号和密码
    return new PasswordAuthentication("admin", "admin@store.com");
   }
  };

  Session session = Session.getInstance(props, auth);

  // 2.创建一个Message，它相当于是邮件内容
  Message message = new MimeMessage(session);

  //设置发送者
  message.setFrom(new InternetAddress("admin@store.com"));

  //设置发送方式与接收者
  message.setRecipient(RecipientType.TO, new InternetAddress(email)); 

  //设置邮件主题
  message.setSubject("这是我们的第一份邮件");

  //设置邮件内容
  message.setContent("哈哈，你到我的商城注册了", "text/html;charset=UTF-8");

  // 3.创建Transport，用于将邮件发送
  Transport.send(message);
