java生成pdf文件并在网页下载

项目用maven进行构建，具体代码及依赖如下：不懂得欢迎提问

需要的maven的pom文件如下：

com.itextpdfitextpdf5.5.10com.itextpdfitext-asian5.2.0empty/** * pdf文件生成以及下载 * @param response */@RequestMapping(value = "yanyan")public void downLoadPDF(HttpServletResponse response){String fileName = "企业基本情况登记表.pdf";OutputStream outputStream = null;try {// 防止中文乱码fileName = URLEncoder.encode(fileName, "UTF-8");response.reset();response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\"");response.setContentType("application/octet-stream;charset=UTF-8");outputStream = new BufferedOutputStream(response.getOutputStream());//生成pdf文件TestModel.createBusinessInfoPDF(outputStream);outputStream.flush();} catch (UnsupportedEncodingException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}finally {try {if (outputStream != null) {outputStream.close();}} catch (IOException e) {e.printStackTrace();}}}

项目是springboot项目，controller的头部已加了RestController，故方法上面只加了RequestMapping注解，项目启动成功后，直接输入访问目录即可下载文件，下载的文件：
