解决cookie中文乱码问题

        //新建cookie并,赋值时,用URLEncoder进行编码
        Cookie cookie = new Cookie("loginname", URLEncoder.encode("雷磊","UTF-8"));
        cookie.setMaxAge(3600);
        response.addCookie(cookie);

        //在获取cookie中的值时,使用URLDecoder进行解码
        Cookie[] cookies = request.getCookies();
        if (cookies != null) {
            for (Cookie cookie : cookies) {
                if (cookie.getName().equals("loginname")) {
                    String name = URLDecoder.decode(cookie.getValue(), "UTF-8");
                }
          }
