        Document document = new Document();



        PdfWriter.getInstance(document, new FileOutputStream(

                "D:/demo.pdf"));

        // BaseFont chinese = BaseFont.createFont("STSong-Light",

        // "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);

        // 使用windows自带的字体

        BaseFont chinese = BaseFont.createFont("C:/windows/fonts/simsun.ttc,1",

                BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

        Font font = new Font(chinese, 14, Font.NORMAL);

        document.close();

    }



    public static void main(String[] args) throws Exception {

        File file = new File("C:\\Users\\zan\\Desktop\\demo.txt");

        byte[] bytes = new byte[(int) file.length()];

        InputStream input = new FileInputStream(file);

        input.read(bytes, 0, (int)file.length());

        printPDF(new String(bytes,"GBK"));

    }

}
