public static String genForwardHtml(String url, Map<String, String> parameters, String charset) {
        StringBuffer returnHtml = new StringBuffer("");
        if (!"".equals(url)) {
            returnHtml.append("<html>");
            String head = "<head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=" + charset
                    + "\" pageEncoding=\"" + charset + "\" />";
            returnHtml.append(head);
            returnHtml.append("<title>loading</title>");
            returnHtml.append("<style type=\"text/css\">");
            returnHtml.append(
                    "body{margin:200px auto;font-family: \"宋体\", Arial;font-size: 12px;color: #369;text-align: center;}");
            returnHtml.append("#1{height:auto; width:78px; margin:0 auto;}");
            returnHtml.append("#2{height:auto; width:153px; margin:0 auto;}");
            returnHtml.append("vertical-align: bottom;}");
            returnHtml.append("</style>");
            returnHtml.append("</head>");
            returnHtml.append("<body>");
            returnHtml.append("<div id=\"3\">交易处理中...</div>");
            returnHtml.append("<form name=\"forwardForm\" action=\"").append(url).append("\" method=\"POST\">");
            System.out.println("WebUtils genForwardHtml::url=" + url);
            Iterator keyIterator = parameters.keySet().iterator();
            while (keyIterator.hasNext()) {
                Object key = keyIterator.next();
                returnHtml.append("  <input type=\"hidden\" name=\"").append(key.toString()).append("\" value=\"")
                        .append((String) parameters.get(key)).append("\"/>");
                System.out.println("WebUtils genForwardHtml::" + key.toString() + "=" + parameters.get(key));
            }
            returnHtml.append("</form>");
            returnHtml.append("<SCRIPT LANGUAGE=\"Javascript\">");
            returnHtml.append("    document.forwardForm.submit();");
            returnHtml.append("</SCRIPT>");
            returnHtml.append("</body>");
            returnHtml.append("</html>");
        }
        return returnHtml.toString();
    }

 

调用方式

String result = WebUtils.genForwardHtml(url, paramMap, "utf-8");
OutputStream out = response.getOutputStream();
out.write(result.getBytes("utf-8"));
out.flush();
