說明：轉換成pdf格式

利用Abobe Acrobat DC打開pdf

步驟：文件 ---->創建------>創建表單----->選擇文件（你轉換成pdf文件）

這里是所要增加的文本域、圖片域等功能按鈕

在你需要的位置增加你說要的功能完成之后進行保存

環境maven

<dependency><groupId>com.itextpdf</groupId><artifactId>itext7-core</artifactId><version>7.1.13</version><type>pom</type></dependency>

生成的模板文件放到適當的位置

所需要生成新的pdf代碼

public @ResponseBody Object getFaceVerificationPdf(GzFaceVerification gzFaceVerification, HttpServletRequest request) throws IOException {try (ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) { try (PdfDocument document = new PdfDocument(new PdfReader( new ClassPathResource('static/moban.pdf').getInputStream()), new PdfWriter(outputStream))) { PdfAcroForm pdfAcroForm = PdfAcroForm.getAcroForm(document, true); //對圖片進行處理（如果不處理在模板中顯示不出圖片） PdfFormField pdfFormField = pdfAcroForm.getField('frontIdCardUrl'); InputStream is = new FileInputStream(new File(gzFaceVerification.getFrontIdCardUrl())); String str = Base64.encodeBytes(StreamUtil.inputStreamToArray(is)); pdfFormField.setValue(str); pdfAcroForm.addField(pdfFormField); PdfFormField pdfFormField1 = pdfAcroForm.getField('reverseIdCardUrl'); InputStream is1 = new FileInputStream(new File(gzFaceVerification.getReverseIdCardUrl())); String str1 = Base64.encodeBytes(StreamUtil.inputStreamToArray(is1)); pdfFormField1.setValue(str1); pdfAcroForm.addField(pdfFormField1); PdfFormField pdfFormField2 = pdfAcroForm.getField('photo'); InputStream is2 = new FileInputStream(new File(gzFaceVerification.getPhoto())); String str2 = Base64.encodeBytes(StreamUtil.inputStreamToArray(is2)); pdfFormField2.setValue(str2); pdfAcroForm.addField(pdfFormField2); pdfAcroForm.getField('frontIdCardUrl').setValue(gzFaceVerification.getFrontIdCardUrl()); pdfAcroForm.getField('reverseIdCardUrl').setValue(gzFaceVerification.getReverseIdCardUrl()); pdfAcroForm.getField('photo').setValue(gzFaceVerification.getPhoto()); pdfAcroForm.getField('comparisonResults').setValue(gzFaceVerification.getComparisonResults()); pdfAcroForm.getField('createTime').setValue(gzFaceVerification.getCreateTime()); pdfAcroForm.flattenFields(); } HttpHeaders httpHeaders = new HttpHeaders(); httpHeaders.setContentType(MediaType.APPLICATION_PDF); httpHeaders.setContentDispositionFormData('attachment', 'test.pdf', Charset.forName('UTF-8')); return ResponseEntity.ok().headers(httpHeaders).body(outputStream.toByteArray());} }
