我正在尝试发送带附件的电子邮件。整个事情工作正常,除了附件发送的部分发送没有扩展名的附件。如何发送邮件的附件在发送时附有扩展名
例如,发送File.rar
将收到file
这是怎么了,我这样做:
public class EmailSender {
public static void main(String[] args) {
String TO = "[email protected]";
String host = "smtp.gmail.com";
String port = "465";
String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
Properties mailConfig = new Properties();
mailConfig.put("mail.smtp.host", host);
mailConfig.put("mail.smtp.socketFactory.port", port);
mailConfig.put("mail.smtp.socketFactory.class", SSL_FACTORY);
mailConfig.put("mail.smtp.auth", "true");
mailConfig.put("mail.smtp.port", port);
Session session = Session.getDefaultInstance(mailConfig,
new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("Username", "Password");
}
});
try {
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(TO));
message.setSubject("Email with Attachment SUBJECT");
BodyPart messageBodyTxt = new MimeBodyPart();
messageBodyTxt.setText("Email with Attachment BODY");
MimeBodyPart messageBodyAttachment = new MimeBodyPart();
String filePath = "D:\\Unlocker1.9.2.rar";
DataSource source = new FileDataSource(filePath);
messageBodyAttachment.setDataHandler(new DataHandler(source));
messageBodyAttachment.setFileName("Unlocker1.9.2" + ".rar");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyTxt);
multipart.addBodyPart(messageBodyAttachment);
message.setContent(multipart);
Transport.send(message);
System.out.println("Email sent successfully");
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
}
