img的src地址是一个请求的方式来显示图片方法

@RequestMapping("getImg2") public void getImg2(HttpServletRequest request, HttpServletResponse response)  throws IOException { FileInputStream fis = null; OutputStream os = null; try {  fis = new FileInputStream("d:/log.png");  os = response.getOutputStream();  int count = 0;  byte[] buffer = new byte[1024 * 8];  while ((count = fis.read(buffer)) != -1) {  os.write(buffer, 0, count);  os.flush();  } } catch (Exception e) {  e.printStackTrace(); } finally {  try {  fis.close();  os.close();  } catch (IOException e) {  e.printStackTrace();  } }}
