  5. controller方法

    @GetMapping("/getPcrDataPdf")
    public void getPcrDataPdf(@RequestParam("id") Integer id, HttpServletResponse response) {
        ObjectRestResponse response1 = null;
        try {
            //todo 获取数据 url tableVos
            //替换数据
            ReplaceAndInsertTableImage image = new ReplaceAndInsertTableImage("123456", url);
            ReplaceAndInsertTable table = new ReplaceAndInsertTable("12345", tableVos);
            //生成pdf
            ClassPathResource classPathResource = new ClassPathResource("1.docx");
            InputStream inputStream = classPathResource.getInputStream();
            File file = new File(PdfUtils.word2pdf(inputStream, "/Users/zyn/Desktop/watch/pdf/" + UUID.randomUUID().toString() + ".pdf", image, table, pcrData));
            response.setContentType("application/pdf");
            response.setCharacterEncoding("UTF-8");
            FileInputStream stream = new FileInputStream(file);
            ServletOutputStream outputStream = response.getOutputStream();
            byte[] bytes = new byte[1024];
            int length = 0;
            while ((length = stream.read(bytes)) > 0) {
                outputStream.write(bytes, 0, length);
            }
            stream.close();
            outputStream.close();
            outputStream.flush();


        } catch (Exception e) {
            e.printStackTrace();
        }
    }
