下面就附上代码把

} }

doc.close();

} catch (IOException e) { System.out.println(e); } catch (DocumentException e) { System.out.println(e); }

}

注意第二个模板分页循环 stamper2 = new PdfStamper(readers, boss);之前记得进行关闭 stamper2.close();

不然会报com.itextpdf.text.exceptions.InvalidPdfException: PDF header signature not found这个错

接下来就是main方法测试了啊

public static void main(String[] args) { Map<String,String> map = new HashMap(); Map<String,String> maps = new HashMap();

map.put("invoiceNo","990696"); map.put("deliverycompany","湖南省长沙市芙蓉区"); map.put("inviocecompany","湖南省长沙市雨花区"); map.put("paymethod","支付宝"); map.put("deliverymethod","邮寄"); map.put("deliverymethod","邮寄"); map.put("forwarder","申通快递"); map.put("deliverydate","2019-9-19"); map.put("orderReference","百度一下,你就知道"); map.put("referenceOrderNo","R1112112222"); map.put("invoice_no","990696"); map.put("invoicedate","2019-9-20"); map.put("dudate","2019-10-20"); map.put("companyNo","224542"); map.put("invoicetotal","230"); map.put("companyName","XXXX有限公司"); map.put("tel","电话 12345678 "+"—"+"传真 0215");

Map<String,String> map2 = new HashMap(); // map2.put("img","C:/Users/pc/Desktop/timg.jpg");

List<List<String>> List = new ArrayList<List<String>>(); for(int i=0;i<=80;i++){ List<String> list = new ArrayList<String>(); list.add("22454223"); list.add("该产品非常好"+i); list.add("200"); list.add("23"); list.add("460"); List.add(list); }

List<String> list11 = new ArrayList<String>(); list11.add(" "); list11.add(" "); list11.add(" "); list11.add("总价"); list11.add("630");

Map<String, List<List<String>>> listMap = new HashMap<String, List<List<String>>>(); listMap.put("eventList", List);

List<List<String>> ListAddress = new ArrayList<List<String>>(); List<String> listdd = new ArrayList<String>(); listdd.add("上海浦东新区"); List<String> listss = new ArrayList<String>(); listss.add("上海浦东新区华夏路"); ListAddress.add(listdd); ListAddress.add(listss); Map<String, List<List<String>>> listMaps = new HashMap<String, List<List<String>>>(); listMaps.put("companyAdress",ListAddress );

Map<String,Object> o=new HashMap(); o.put("datemap",map); // o.put("imgmap",map2); o.put("list",listMap); o.put("listss",listMaps); String uid=CommonUtils.uuid(); System.out.println(uid+"uid"); String newPDFPath ="C:/Users/pc/Desktop/"+uid+".pdf"; pdfout(o,newPDFPath);
