Properties props = new Properties();
            Session session = Session.getDefaultInstance(props, null);
            Message message = new MimeMessage(session,
request.getInputStream());

            String subject = message.getSubject();

            DataHandler dataHandler = message.getDataHandler();
            DataSource dataSource = dataHandler.getDataSource();
            MimeMultipart mimeMultipart = new MimeMultipart
(dataSource);

            Part part1 = mimeMultipart.getBodyPart(0);
            // get the content use common io, i use chinese, so i set

            String content = IOUtils.toString((InputStream)
part1.getContent(), "gb2312");
