直接给URL整体中文字符编码

    public static String encode(String url, String encode)
            throws UnsupportedEncodingException {
        StringBuilder sb = new StringBuilder();
        StringBuilder noAsciiPart = new StringBuilder();
        for (int i = 0; i < url.length(); i++) {
            char c = url.charAt(i);
            if (c > 255) {
                noAsciiPart.append(c);
            } else {
                if (noAsciiPart.length() != 0) {
                    sb.append(URLEncoder.encode(noAsciiPart.toString(), encode));
                    noAsciiPart.delete(0, noAsciiPart.length());
                }
                sb.append(c);
            }
        }
        return sb.toString();
    }
