Cookie中包含空格（特殊字符）的解决方案

Cookie中包含空格可能会出现空格之后的数据丢失的情况。
解决办法：使用URLEncoder.encode()对cookie进行编码,再使用URLDecoder.decode()进行解码
Response:

StringBuilder cookie = new StringBuilder();
        for (BasicNameValuePair basicNameValuePair : basicNameValuePairs) {
            cookie.append(URLEncoder.encode(basicNameValuePair.getName(), String.valueOf(Charsets.UTF_8)))
                  .append("=").append(URLEncoder.encode(basicNameValuePair.getValue(), String.valueOf(Charsets.UTF_8)))
                  .append(";");
        }
        response.setHeader("Set-Cookie", String.valueOf(cookie));

Request

URLDecoder.decode(cookie.getValue(), String.valueOf(Charsets.UTF_8))

问题就解决了。

有一个问题：

当服务器为Jetty的时候，通过`Response.addCookie(cookie)会报错：

Cookie cookie = new Cookie("lastVisitTime", DateFormatUtils.format(new Date(), Const.TIME_STAMP_FORMATTER));
cookie.setMaxAge(24 * 60 * 60);
response.addCookie(cookie);

只能通过setHeader的方式添加cookie。
但是同样的代码，使用addCookie的方式放在tomcat服务器上是完全OK的。不知道啥问题。
