| @RequestMapping("/getimage")
public void getimage(HttpServletResponse response) throws IOException{
BufferedImage image = ImageIO.read(Files.newInputStream(Paths.get("D:\\laiscdata\\1.png")));
response.setHeader("Cache-Control", "no-store,no-cache");
response.setContentType("image/jpeg");
ServletOutputStream out = response.getOutputStream();
ImageIO.write(image,"jpg",out);
}
