老聂确实是个牛人--cookie存储中文

写Cookie：
Cookie chineseCookie = new Cookie( "chineseCookie ", URLEncoder.encode( "中文 ", "UTF-8 "));
chineseCookie.setMaxAge(36000);
response.setCharacterEncoding( "UTF-8 ");
response.addCookie(chineseCookie);

读Cookie：
Cookie[] cookies = request.getCookies();
for (int i = 0; i < cookies.length; i++) {
if ( "chineseCookie ".equals(cookies[i].getName())) {
String temp = cookies[i].getValue();
temp = URLDecoder.decode(temp, "UTF-8 ");
System.out.println( "chineseCookie : " + temp); //测试打印语句
}
}
