Question

我正在使用Itext创建一个pdf，创建之后，我通过将其转换为byte []在邮件中发送它我能够生成byte []并通过在线工具pdf检查，他们能够从我的byte []中生成pdf 但是当我从Java代码中发送此byte []时，文件已损坏。

下面是我的代码

这是我将pdf转换为字节的一半[]

document.close();
byte[] bytes = baos.toByteArray();
bytes = Base64.getEncoder().encode(bytes);
System.out.println(new String(bytes));
System.out.println("Done");
sendEmail(bytes);

从这里我要发送邮件

public static void sendEmail(byte[] pdf) throws IOException {
          System.out.println("Starte");
          System.out.println(new String(pdf));
        final String username = "b*****@gmail.com";
        final String password = "*****";

        Properties prop = new Properties();
        prop.put("mail.smtp.host", "smtp.gmail.com");
        prop.put("mail.smtp.port", "465");
        prop.put("mail.smtp.auth", "true");
        prop.put("mail.smtp.socketFactory.port", "465");
        prop.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

        Session session = Session.getInstance(prop,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(username, password);
                    }
                });

        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("*****@gmail.com"));
            message.setRecipients(
                    Message.RecipientType.TO,
                    InternetAddress.parse("******@gmail.com, *****@gmail.com")
            );
            message.setSubject("Testing Gmail SSL");
            message.setText("Dear Mail Crawler,"
                    + "\n\n Please do not spam my email!");


            Multipart multipart = new MimeMultipart(); //1
         // Create the attachment part
         BodyPart attachmentBodyPart = new MimeBodyPart(); //2
         attachmentBodyPart.setDataHandler(new DataHandler(new ByteArrayDataSource(pdf,"application/pdf"))); //2
         attachmentBodyPart.setFileName("Hello.pdf"); // 2
         multipart.addBodyPart(attachmentBodyPart); //3
         // Create the HTML Part
         BodyPart htmlBodyPart = new MimeBodyPart(); //4
         htmlBodyPart.setContent("Dear Mail Crawler,"
                 + "\n\n Please do not spam my email!" , "text/html"); //5
         multipart.addBodyPart(htmlBodyPart); // 6
         // Set the Multipart's to be the email's content
         message.setContent(multipart); //7


            Transport.send(message);

            System.out.println("Done");

        } catch (MessagingException e) {
            e.printStackTrace();
        }

    }

请让我知道代码有什么问题任何帮助都将得到
