cookie添加中文encoding/decoding

添加时编码，读取是解码，否则编译不过

    Cookie cookie=new Cookie("姓名","黄嘎兵");
    respose.addCookie(cookie);

编译不过

要这样做

    Cookie cookie=new Cookie(URLEncoder.encode("姓名"),URLEncoder.encode("黄嘎兵"));
    response.addCookie(cookie);

                String cookieName=URLDecoder.decode(cc.getName());
                String cookieValue=URLDecoder.decode(cc.getValue());
