關於過濾器無法過濾enctype="multipart/form-data"表單提交數據的問題

　　寫過濾器遇到如下問題：普通表單可正常過濾，multipart/form-data類型表單無法過濾提交的內容

　　修改如下后正常

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest httpRequest = (HttpServletRequest) request;
        String enctype = httpRequest.getContentType();
        if (StringUtils.isNotBlank(enctype) && enctype.contains("multipart/form-data")) {
            CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver(
                    httpRequest.getSession().getServletContext());
            MultipartHttpServletRequest multipartRequest = commonsMultipartResolver.resolveMultipart(httpRequest);

            XssHttpServletRequestWrapper xssRequest = new XssHttpServletRequestWrapper(multipartRequest);
            chain.doFilter(xssRequest, response);
        } else {
            XssHttpServletRequestWrapper xssRequest = new XssHttpServletRequestWrapper(httpRequest);
            chain.doFilter(xssRequest, response);
        }
    }
