### 代码如下 ```java @RequestMapping(value = "getVideo") public void getVideo(HttpServletRequest request, HttpServletResponse response) throws IOException { File file = new File("e:/" + request.getParameter("name")); try (InputStream in = new FileInputStream(file); ServletOutputStream out = response.getOutputStream();) { int length; byte[] buffer = new byte[4 * 1024]; // 向前台输出视频流 while ((length = in.read(buffer)) > 0) { out.write(buffer, 0, length); } } catch (FileNotFoundException e) { System.out.println("文件读取失败, 文件不存在"); } } ```
