问题:

I am using java mail to get emails from gmail with attachments, the attachment come as String in the content, how I can convert it to file?

this what I got

Content :
begin 644 myfile.csv
M(E-T871U<R(L(E-T87)T(BPB4W1A<G0@9&%T92(L(E-T87)T('1I;64B+")%
M;F0B+")%;F0@9&%T92(L(D5N9"!T:6UE(BPB0V%L;&EN9R!C=7-T;VUE<B(L

end

Object content = message.getContent();
            if (content instanceof String) {//here I got the attachment
                System.out.println(content);
            } else if (content instanceof Multipart) {
                Multipart multiPart = (Multipart) content;
                procesMultiPart(multiPart);
            }

Looks like you have a single part message with uuencoded content. If the message was properly formatted with a Content-Transfer-Encoding header of "uuencode", JavaMail would decode it automatically for you. But it looks like it is not. You can decode it yourself using:

InputStream is = MimeUtility.decode(message.getInputStream(), "uuencode");

Then read the input stream to get the decoded data, e.g., to copy it to a file.
