1、导入需要的jar包：itext-asian-5.2.0.jar itextpdf-5.5.11.jar。

2、新建word文档，创建模板，将文件另存为pdf，并用Adobe Acrobat DC打开编辑，点击右侧【准备表单】后点击【开始】

3、在需要插入数据的空白处，右击，点击【文本域】，将文本域拖放到你想要的位置，更改域名称为你传入的变量名。

4、保存文件，将文件放到项目中。生成pdf代码如下：

1 public static void creatPdf(Map
      
        map,String filePath) { 2         try { 3             BaseFont bf = BaseFont.createFont("c://windows//fonts//simsun.ttc,1", BaseFont.IDENTITY_H, 4                     BaseFont.EMBEDDED); 5             FileOutputStream out = new FileOutputStream(filePath);// 输出流 6             PdfReader reader = new PdfReader(TemplateToWord.class.getResource("/com/cn/business/templates/report.pdf"));// 读取pdf模板 7             ByteArrayOutputStream bos = new ByteArrayOutputStream(); 8             PdfStamper stamper = new PdfStamper(reader, bos); 9             stamper.setFormFlattening(true);10             AcroFields form = stamper.getAcroFields();11             // 文字类的内容处理12             Map
       
         datemap = (Map
        
         ) map.get("datemap");13             form.addSubstitutionFont(bf);14             for (String key : datemap.keySet()) {15                 String value = datemap.get(key);16                 form.setField(key, value);17             }18             // 图片类的内容处理19             Map

                 list = lists.get(i);67 for(int j=0;j
