我正在使用 apache common email library发送电子邮件,如下
// Create the attachment
EmailAttachment attachment = new EmailAttachment();
attachment.setPath("mypictures/john.jpg");
attachment.setDisposition(EmailAttachment.ATTACHMENT);
attachment.setDescription("Picture of John");
attachment.setName("John");
// Create the email message
MultiPartEmail email = new MultiPartEmail();
email.setHostName("mail.myserver.com");
email.addTo("jdoe@somewhere.org", "John Doe");
email.setFrom("me@apache.org", "Me");
email.setSubject("The picture");
email.setMsg("Here is the picture you wanted");
// add the attachment
email.attach(attachment);
// send the email
email.send();
我想显示进度条,直到附加文件并发送..
我们该怎么办?
