java实现 浏览器图片展示

功能简单，直接贴代码

private void imageShow(HttpServletResponse response, @ModelAttribute("url") String url)
            throws IOException {
        String s2 = new String(url.getBytes("ISO-8859-1"),"utf-8");
        OutputStream os = response.getOutputStream();
        File file = new File("d:\\img\\"+s2);
        FileInputStream fips = new FileInputStream(file);
        ByteArrayOutputStream bops = new ByteArrayOutputStream();
        int data = -1;
        while ((data = fips.read()) != -1) {
            bops.write(data);
        }
        byte[] btImg = bops.toByteArray();
        os.write(btImg);
        os.flush();

    }
