Spring Boot Freemark HTML 生成 PDF、生成水印Logo、docx文件生成PDF，Jar包运行可读取模板文件、字体文件

用于通过模板生成PDF，在项目中生成个人授权协议函、个人电子保单、流水报表，数据报表等，将HTML静态模板写出来后，将数据替换成动态数据即可。

simsun.ttc 为字体文件

1.HTML 生成 PDF

HttpHeaders 写法

@GetMapping("/pdf")public ResponseEntity<?> export(HttpServletResponse response) {try {HttpHeaders headers = new HttpHeaders();Map<String, Object> dataMap = new HashMap<>(16);dataMap.put("text", "张三");String htmlStr = FreeMarkUtils.freemarkerRender(dataMap, "templates.ftl");byte[] pdfBytes = FreeMarkUtils.createPDF(htmlStr, "simsun.ttc");if (pdfBytes != null && pdfBytes.length > 0) {String fileName = System.currentTimeMillis() + (int) (Math.random() * 90000 + 10000) + ".pdf";headers.setContentDispositionFormData("attachment", fileName);headers.setContentType(MediaType.APPLICATION_OCTET_STREAM);return new ResponseEntity<byte[]>(pdfBytes, headers, HttpStatus.OK);}} catch (Exception e) {e.printStackTrace();}HttpHeaders headers = new HttpHeaders();headers.setContentType(MediaType.APPLICATION_JSON_UTF8);return new ResponseEntity<>("{ \"code\" : \"404\", \"message\" : \"not found\" }", headers, HttpStatus.NOT_FOUND);}

Response 写法

    @GetMapping("/pdf")public void export(HttpServletResponse response) {InputStream inputStream = null;try {// 设置参数Map<String, Object> dataMap = new HashMap<>(16);dataMap.put("text", "张三");String htmlStr = FreeMarkUtils.freemarkerRender(dataMap, "template.ftl");byte[] data = FreeMarkUtils.createHtml2Pdf(htmlStr, "simsun.ttc");// 设置文件名String fileName = System.currentTimeMillis() + (int) (Math.random() * 90000 + 10000) + ".pdf";// 浏览器直接下载文件generateFile(response, data, fileName);// 获取输入流inputStream = new ByteArrayInputStream(data);// 输入流保存阿里云final String url = OssBootUtil.upload(inputStream, "upload/agree/" + fileName);log.info(url);} catch (Exception e) {e.printStackTrace();} finally {try {if (inputStream != null) {inputStream.close();}} catch (IOException ex) {ex.printStackTrace();}}}@GetMapping("/doc")public void doc(HttpServletResponse response) {Map<String, Object> dataMap = new HashMap<>();dataMap.put("name", "zhangsan");String fileName = System.currentTimeMillis() + (int) (Math.random() * 90000 + 10000) + ".doc";generateFile(response, FreeMarkUtils.freemarkerRender(dataMap, "test.ftl").getBytes(StandardCharsets.UTF_8), fileName);}@GetMapping("/doc2pdf")public void doc2pdf(HttpServletResponse response) {Map<String, Object> dataMap = new HashMap<>();dataMap.put("name", "张三");final byte[] data = FreeMarkUtils.createDocx2Pdf(dataMap, "document.ftl", "templates/test3.docx");String fileName = System.currentTimeMillis() + (int) (Math.random() * 90000 + 10000) + ".pdf";generateFile(response, data, fileName);}/*** 下载文件* @param response 相应* @param data 数据* @param fileName 文件名*/private void generateFile(HttpServletResponse response, byte[] data, String fileName) {response.setHeader("content-Type", "application/octet-stream");response.setCharacterEncoding("utf-8");response.setHeader("Content-disposition", "attachment;filename=" + fileName);try {response.getOutputStream().write(data);} catch (IOException e) {e.printStackTrace();} finally {try {response.getOutputStream().close();} catch (IOException e) {e.printStackTrace();}}}

2. docx 文件生成PDF

新建word 2007 test3.docx

复制文件，重命名为test3.zip,解压后

复制word/document.xml文件到项目中 document.ftl，更改文件内容变量

导出PDF工具类
