    // 1.创建一个程序与邮件服务器会话对象 Session
    Properties props = new Properties();
    props.setProperty("mail.transport.protocol", "SMTP");//发邮件的协议
    props.setProperty("mail.host", "localhost");//发送邮件的服务器地址
    props.setProperty("mail.smtp.auth", "true");// 指定验证为true

    // 创建验证器
    Authenticator auth = new Authenticator() {
        public PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("tom", "12345");//发邮件的账号的验证
        }
    };

    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);

    message.setFrom(new InternetAddress("tom@itheima32.com")); // 设置发送者

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

    message.setSubject(subject);//邮件的主题

    message.setContent(emailMsg, "text/html;charset=utf-8");

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