java 上传下载文件由中文引起的问题

上传下载附件时，对中文名称的文件要进行转码才能正常适应IE firefox chrome等主流浏览器

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

        InputStream inputStream = null;
        try
        {
            inputStream = this.uploadFileFacade.downloadOrderAttachment(location);

            response.encodeURL("UTF-8");
          
            String headerValue = "attachment;";
            headerValue += " filename=\"" + encodeURIComponent(fileName) + "\";";
            headerValue += " filename*=utf-8''" + encodeURIComponent(fileName);
            response.setHeader("Content-Disposition", headerValue);
            
            final byte[] b = new byte[1024];

            int len;
            while ((len = inputStream.read(b)) != -1)
            {
                response.getOutputStream().write(b, 0, len);

            }
        }
        catch (final Exception e)
        {
            // YTODO Auto-generated catch block
            e.printStackTrace();
        }
        finally
        {
            inputStream.close();
        }

public static String encodeURIComponent(final String value)
    {
        try
        {
            return URLEncoder.encode(value, "UTF-8").replaceAll("\\+", "%20");
        }
        catch (final UnsupportedEncodingException e)
        {
            e.printStackTrace();
            return null;
        }
    }

前端JS中进行转码，避免浏览器中出现中文（特别是IE）

   '<a class="href" deleteLocation="'+encodeURI(locationUrl)+'">删除</a></div>'
