JavaMail发送了BitSarver文件而不是pdf文件

我创建了一种使用带有多文件附件的java GUI发送邮件的方法。当该方法发送邮件时,它将附件文件类型如microsoft office和pdf作为BitSarver发送到接收邮件。我需要提交文件以发送类型,以便其他自动系统可以通过阅读附件文件并打印它来工作。

这是方法。

    static public boolean sendMail(String to,String subject,String text_filed)
{
    Properties props = new Properties();
    props.put("mail.smtp.host","smtp.gmail.com");
    props.put("mail.smtp.socketFactory.port ","465");
    props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.auth","true");
    props.put("mail.smtp.port","465");
    Session session = Session.getDefaultInstance(props,
            new javax.mail.Authenticator(){
                protected PasswordAuthentication getPasswordAuthentication()
                {
                    return new PasswordAuthentication("eamil", pass);
                }
            }
    );
    try 
    {
        Message m = new MimeMessage(session);
        m.setFrom(new InternetAddress(userMAil));

        System.out.println("from "+userMAil);

        m.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));

        System.out.println("to "+to);

        m.setSubject(subject);

        System.out.println("the subject "+subject);

        MimeBodyPart bodypart = new MimeBodyPart();
        bodypart.setText(text_filed);
        Multipart multipart = new MimeMultipart();
        multipart.addBodyPart(bodypart);

        System.out.println("the content "+text_filed);
        for(int i = 0;i< main_controller.attachments_path.size();i++)
        {   
            bodypart = new MimeBodyPart();
            DataSource source = new FileDataSource(main_controller.attachments_path.get(i));
            System.out.println("the file location"+main_controller.attachments_path.get(i));
            bodypart.setDataHandler(new DataHandler(source));
            //bodypart.setFileName(main_controller.filesFrame.getFilename());

            System.out.println("the file name"+main_controller.filesFrame.getFilename());
            multipart.addBodyPart(bodypart);
        }


        m.setContent(multipart);
        //m.setText(text_filed);

        Transport.send(m);

        JOptionPane.showMessageDialog(null, "done!");
        return true;
    }
    catch(Exception e)
    {
        String m = e.getMessage();
        JOptionPane.showMessageDialog(null, e);
        System.out.println(m);
        return false;
    }
}
希望你能帮助我:D

似乎问题可能与此有关:

尝试在提交之前调用MimeMessage.saveChanges()以从DataHandler中正确填充内容类型。

JavaMail通过JavaBeans Activation Framework(JAF)根据文件扩展名选择MIME类型。 “已知”文件扩展名列表相对较小。您可以按照MimetypesFileTypeMap javadocs中的说明添加它。或者,您可以使用MimeBodyPart.attachFile方法并直接指定MIME类型。

哦,你要清理这些common JavaMail mistakes
