Java 邮件。回复消息分为消息和附件

Question

我设置的短信作为文本文件附在信中。我不明白为什么会这样。

replied letter example

public void sendEmail(MimeMessage message, String textMessage){
        Session session = getSession();
        Transport transport = null;
        BodyPart part = new MimeBodyPart();

        MimeMultipart multipart = new MimeMultipart();
        try {
            String recipients = InternetAddress.toString(message.getRecipients(Message.RecipientType.TO));             
            MimeMessage replyMessage = (MimeMessage) message.reply(false);
            replyMessage.setSubject("RE: " + message.getSubject());
            replyMessage.setFrom(new InternetAddress(APPROVER));
            replyMessage.setReplyTo(message.getReplyTo());

            replyMessage.addRecipients(Message.RecipientType.TO, recipients);

            part.setContent(message.getContent(), message.getContentType());
            multipart.addBodyPart(part);
            part = new MimeBodyPart();
            part.setText(textMessage);
            multipart.addBodyPart(part);
            replyMessage.setContent(multipart);

            transport = session.getTransport("smtp");
            transport.connect(SERVER_HOST, APPROVER, APPROVER_PASSWORD);
            transport.sendMessage(replyMessage, replyMessage.getAllRecipients());
        } catch (IOException|MessagingException e) {
            e.printStackTrace();
        }
    }

这是因为您首先附加原始消息，然后在原始消息之后附加回复文本。大多数邮件程序会将回复文本显示为附件。先放回复文字。此外，原始邮件通常不会作为回复的附件添加。原始消息的文本通常包含在回复的文本中。请参阅此 JavaMail 常见问题解答条目 composing the reply text以及此 JavaMail 常见问题解答条目 finding the main body text in the original message .
