JAVA-getBytes返回不带BOM的UTF-8

Question

I send a txt file by email in this way. File's data is in a StringBuffer.

File construction :

StringBuffer lBufferFinal = new StringBuffer();
// Put some text in lBufferFinal
FichierByteVO lFichier = new FichierByteVO();
    lFichier.setFileName("Statistic.txt");
    lFichier.setMIMEType("text/plain");
    lFichier.setFile(lBufferFinal.toString().getBytes(Charset.forName("UTF-8")));

Adding the file in an email :

MimeMessage lMessage = new MimeMessage(lSession);
// Do thing tu put sender, receiver, subject etc to the MimeMessage
Multipart = new MimeMultipart();
BodyPart lMessageBodyPart = new MimeBodyPart();
lMessageBodyPart.setText("Here is an email !");
lMultipart.addBodyPart(lMessageBodyPart);
lMessageBodyPart = new MimeBodyPart();
DataHandler lDataHandler = new DataHandler(new ByteArrayDataSource(lFichier.getFile(), lFichier.getMIMEType()));
        lMessageBodyPart.setDataHandler(lDataHandler);
                    lMessageBodyPart.setFileName(lFichier.getFileName());
        lMultipart.addBodyPart(lMessageBodyPart);
    }
    lMessage.setContent(lMultipart);

The file I receive by email is by default open as "UTF-8 without BOM" in notepad++, or in excel (who does not recognize accents).

So I need to open with excel, so to have UTF-8 with BOM encoding.

Do you have any suggestions ?

Answer 1

最后，我使用.CSV扩展名和ISO-8859-1，效果很好！

Answer 2

It is not convenient use the BOM. You can put the encoding of the mail like this:

JavaMailSenderImpl mailer = new JavaMailSenderImpl();
...
mailer.setDefaultEncoding("ISO-8859-1");

This will recognize the accents
