java cookie 使用

最近闲来无聊，写了个cookie的用例：

1. cookie组成： 名称、值、过期时间、路径和域

2.构造cookie 

/**cookie test***/
		Cookie nameCookie = new Cookie(Mapping.NAME_COOKIE,name);
		nameCookie.setMaxAge(60);
		Cookie passCookie = new Cookie(Mapping.PASSWORD_COOKIE,password);
		passCookie.setMaxAge(60);
		response.addCookie(nameCookie);
		response.addCookie(passCookie);

 3.取出cookie：

/**
   * read cookie
   * @param request
   */
   Cookie[] cks = request.getCookies();
   Hashtable<String,String> ckTable = new Hashtable<String,String>(0);
   for(int i = 0;cks != null && i < cks.length;i++){
    Cookie ck = cks[i];
    if(ck.getName() != null && !ck.getName().equals("")){
     ckTable.put(ck.getName(), ck.getValue());
    }
   }
   String name = "";
   String password = "";
   if(ckTable.get(Mapping.NAME_COOKIE) != null){
    name = ckTable.get(Mapping.NAME_COOKIE);
   }
   if(ckTable.get(Mapping.PASSWORD_COOKIE) != null){
    password = ckTable.get(Mapping.PASSWORD_COOKIE);
   }
   System.out.println("$$$$$$$$$$$ cookie-- name:" + name + " password:" +  password);
   GetSessionBusi busi = GetSessionBusi.getInstance();
   busi.getSession(request);
   
   request.setAttribute("name", name);
   request.setAttribute("password", password);
