img標簽中src引用絕對的路徑報錯：Not allowed to load local resource: file:///D://data/upload/banner.png

瀏覽器直接訪問file:///D://data/upload/banner.png是可以的，但在頁面里就是不顯示

解決：不配置絕對路徑，src里訪問后台，參數為圖片名稱，通過應用服務器獲取圖片輸出

jsp：

后台：

 @RequestMapping("/image/{filename}")
 public void showImageByType(@PathVariable String filename, HttpServletRequest request, HttpServletResponse response) throws Exception {
        InputStream inputStream = null;
        OutputStream writer = null;
        try {
            String root = ReadeGlobePa.getValueByProper("fileSaveDir");
            filename = filename.replace("/", "");
            filename = filename.replace("..", "");
            inputStream = new FileInputStream(new File(root + "/upload/" + filename));
            writer = response.getOutputStream();

            byte[] buf = new byte[1024];
            int len = 0;
            while ((len = inputStream.read(buf)) != -1) {
                writer.write(buf, 0, len); //寫
            }
            inputStream.close();
        } catch (FileNotFoundException e) {
            response.setStatus(404);
        } catch (Exception e) {
//            logger.error(e.getMessage(), e);
        } finally {
            try {
                if (inputStream != null) {
                    inputStream.close();
                }
                if (writer != null) {
                    writer.close();
                }
            } catch (IOException e) {
                logger.error(e.getMessage(), e);
            }
        }
    }
