pdf模板生成pdf文件

依赖itext-2.1.7.jar、iTextAsian.jar

public class Test {
    public static void main(String[] args) {
        String tmpName = "E:/pdf.pdf";// pdf模板
        try {

            //PdfContentByte under = stamper.getUnderContent(1);
            BaseFont bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);
            ArrayList<BaseFont> list = new ArrayList<BaseFont>();
            list.add(bf);
            AcroFields fields = stamper.getAcroFields();
            fields.setSubstitutionFonts(list);

            fos.close();
            bos.close();
