templates.ftl 放入resource/templates文件目录中

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);
    }
