首先下载Adobe Acrobat DC工具：

通过工具打开pdf母版，点击创建表单，然后插入文本，文本变量就是我们java代码中需要插入的值，文本域可以设置字体，颜色大小等信息

调用如下：
Map<String,String> map = new HashMap();
map.put("courseDate",jo.getString("certDate"));
map.put("printName",jo.getString("printedName"));
map.put("subTitle",jo.getString("subTitle"));
map.put("certNo","Serial Number:"+jo.getString("certNo"));
Map<String,Object> o=new HashMap();
o.put("datemap",map);
File pdfFile=PdfUtils.pdfout(o,path);
