java 生成有模板表单域的 PDF
1- 准备PDF域 数据

有PDF模板的情况下，重新绘制PDF
1- 使用 Adobe Acrobat DC
2- 编辑PDF > 准备表单
代码中读取PDF模板，按照排版好的域，顺序写入内容
1 AcroFields form = stamper.getAcroFields();
for (String key : dataParamMap.keySet()) { int ilen = dataParamMap.get(key).toString().length(); if(key == "学校" || key == "队伍"){ if(ilen >= 20 && ilen < 40){ form.setFieldProperty(key, "textsize", new Float(10), null); }else if(ilen >= 40 && ilen <= 55){ form.setFieldProperty(key, "textsize", new Float(7), null); }else if(ilen > 55){ form.setFieldProperty(key, "textsize", new Float(6), null); } } form.setField(key,dataParamMap.get(key).toString()); }
