当我发送附件时,我没有看到正文消息(message.setText(this.getEmailBody());)在电子邮件中。如果没有附件,电子邮件将与正文消息一起显示。电子邮件将发送到 Gmail 帐户。有什么线索为什么会这样吗?
MimeMessage message = new MimeMessage(session_m);
message.setFrom(new InternetAddress(this.getEmailSender()));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(this.getEmailRecipient()));
message.setSubject(this.getEmailSubject());
message.setText(this.getEmailBody()); //This won't be displayed if set attachments
Multipart multipart = new MimeMultipart();
for(String file: getAttachmentNameList()){
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.attachFile(this.attachmentsDir.concat(file.trim()));
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
}
Transport.send(message);
System.out.println("Email has been sent");
您需要使用以下方法:
// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();
// Fill the message
messageBodyPart.setText(body);
messageBodyPart.setContent(body, "text/html");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
//Add the bodypart for the attachment(s)
// Send the complete message parts
message.setContent(multipart); //message is of type - MimeMessage
您需要分成两部分才能执行此操作:
Multipart multipart = new MimeMultipart();
// content part
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText(content);
messageBodyPart.setContent(content, "text/html");
multipart.addBodyPart(messageBodyPart);
BodyPart attachmentPart = new MimeBodyPart();
DataSource source = new FileDataSource(file);
attachmentPart.setDataHandler(new DataHandler(source));
attachmentPart.setFileName(file.getName());
multipart.addBodyPart(attachmentPart);
