说明：转换成pdf格式
利用Abobe Acrobat DC打开pdf
步骤：文件 ---->创建------>创建表单----->选择文件（你转换成pdf文件）
这里是所要增加的文本域、图片域等功能按钮
在你需要的位置增加你说要的功能完成之后进行保存
环境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适当的位置
所需要生成新的pdf代码
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);
//对图片进行处理（如果不处理在模板中显示不出图片）
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());
}
}
