JavaWeb实现了文件下载的功能，在手机端点击下载，没有提示下载的本地，只会马上解析显示

@Controller
@RequestMapping("/file")
public class FileController {

@Value("#{configProperties['downloadPath']}")
private String downloadPath;

@RequestMapping(value = "/download", method = RequestMethod.GET)
public void download(String fileName, HttpServletRequest request, HttpServletResponse response) throws IOException {

    String transcoding = new String(fileName.getBytes("iso8859-1"),"utf-8");
    String downloadName = URLEncoder.encode(transcoding, "UTF-8");
    response.setCharacterEncoding("utf-8");
    response.setContentType("application/octet-stream");
    response.setHeader("Content-Disposition", "attachment;fileName=" + downloadName);

    InputStream is = null;
    OutputStream os = null;
    try {
        String path = request.getServletContext().getContextPath();
        is = new FileInputStream(new File(downloadPath + transcoding));
        os = response.getOutputStream();
        byte[] b = new byte[2048];
        int length;
        while ((length = is.read(b)) > 0) {
            os.write(b, 0, length);
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        os.close();
        is.close();
    }
}

}

就很普通的一段下载代码，在PC没问题的，但是在手机点击下载(txt/jpg)，就会马上解析然后展示在页面上，现在希望是实现在手机端点击下载的时候提示下载到手机本地，之前没做过在手机端的下载，大家指点下谢谢。
