   // 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() {

     //设置发件人的账号和密码

     return new PasswordAuthentication( "admin" , "admin@store.com" );

   // 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);
