1. 制作pdf模板
使用Adobe Acrobat打开pdf文件，在需要填充文字、或者图片的地方插入表单，如下图
这里只截图了一部分，其他类似
2. 添加itextpdf依赖
3. 编写工具类，根据模板，替换文字和图片，生成pdf文件
/*** 根据模板生成pdf* @param data数据* @param imageMap图片数据 * @param outfile 生成文件* @param templateFile 模板文件* @return 文件保存全路径文件*/public static File createPDF(Map<String, Object> data, Map<String,String> imageMap, String outfile, String templateFile) {PdfReader reader = null;AcroFields s;PdfStamper ps;ByteArrayOutputStream bos = null;//输出文档路径及名称File outFile = new File(outfile);try {reader = new PdfReader(templateFile);bos = new ByteArrayOutputStream();ps = new PdfStamper(reader, bos);s = ps.getAcroFields();// 处理文字for (String key : data.keySet()) {if (data.get(key) != null) {s.setField(key, data.get(key).toString());}}// 处理图片for (String key : imageMap.keySet()) {String value = imageMap.get(key);String imgpath = value;int pageNo = s.getFieldPositions(key).get(0).page;Rectangle signRect = s.getFieldPositions(key).get(0).position;float x = signRect.getLeft();float y = signRect.getBottom();// 根据路径读取图片Image image = Image.getInstance(imgpath);// 获取图片页面PdfContentByte under = ps.getOverContent(pageNo);// 图片大小自适应image.scaleToFit(signRect.getWidth(), signRect.getHeight());// 设置图片位置，以为我们以左下角为起始点，所以这里x、y加上偏移量，偏移量为计算的居中量image.setAbsolutePosition(x + (signRect.getWidth()-image.getScaledWidth())/2, y + (signRect.getHeight()-image.getScaledHeight())/2);// 添加图片under.addImage(image);}// 如果为false那么生成的PDF文件还能编辑，一定要设为trueps.setFormFlattening(true);ps.close();//生成pdf路径存放的路径OutputStream fos = new FileOutputStream(outfile);fos.write(bos.toByteArray());fos.flush();fos.close();bos.close();} catch (IOException | DocumentException e) {log.error("读取文件异常");e.printStackTrace();} finally {try {bos.close();reader.close();} catch (IOException e) {log.error("关闭流异常");e.printStackTrace();}}return outFile;}
4. 测试，图片可以为网络图片，也可以为本机图片
public static void main(String[] args) {String templatePath ="D:"+File.separator+"temp"+File.separator+"ftl"+File.separator+"report.pdf";String outPath = "D:"+File.separator+"temp"+File.separator+"report"+File.separator+"test.pdf";Map<String, Object> dataMap = new HashMap<>(10);dataMap.put("qymc", "XX市申海机械设备股份有限公司");dataMap.put("qyjc","申海机械");dataMap.put("qymc1","XX市申海机械设备股份有限公司");dataMap.put("qyjc1","申海机械");dataMap.put("kkbxjz","330.89万元");dataMap.put("ppjz","334.74万元");dataMap.put("jzryear","");dataMap.put("jzrmonth","12");dataMap.put("jzrday","31");dataMap.put("beginyear","");dataMap.put("beginmonth","06");dataMap.put("beginday","05");dataMap.put("endyear","");dataMap.put("endmonth","06");dataMap.put("endday","04");dataMap.put("k","0.2290");dataMap.put("zhzs","0.2780");dataMap.put("q","0.3468");dataMap.put("w","0.2775");dataMap.put("s","0.2710");dataMap.put("pjdx","XX市申海机械设备股份有限公司");dataMap.put("kkbxjz1","330.89万元");dataMap.put("ppjz1","334.74万元");dataMap.put("jzr","12月31日");dataMap.put("kkbxjz2","330.89万元");dataMap.put("wtf","太原市申海机械设备股份有限公司");dataMap.put("pjdx1","申海机械");dataMap.put("jzr1","12月31日");dataMap.put("bzrq",".06.06");dataMap.put("zsbh","AP_06023");dataMap.put("yxq",".06.04");Map<String,String> imageMap = new HashMap<>(5);imageMap.put("logo","http://192.168.50.250:9000/group3/11/logo.png");imageMap.put("yqsy","D:/temp/yqsy.png");imageMap.put("jzwd","D:/temp/jzwd.png");imageMap.put("logo1","http://192.168.50.250:9000/group3/11/logo.png");imageMap.put("qrcode","D:/temp/qrcode.png");try {createPDF(dataMap,imageMap,outPath,templatePath);} catch (Exception e) {e.printStackTrace();}}
