img的src地址是一个请求的方式来显示图片方法

1、jsp

 <img 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(); } }}
