java.lang.IllegalArgumentException指不合法的參數(shù)異常，從你的參數(shù)看你應該是想把一個List集合放到cookie中，cookie只支持存放字符串。

Love麗珊list是定義的一個字符串 <% String list =""; //從客戶端獲得Cookies集合 Cookie[] cookies = request.getCookies(); //遍歷這個Cookies集合 if(cookies!=null&&cookies.length>0) { for(Cookie c:cookies) { if(c.getName().equals("ListViewCookie")) { list = c.getValue(); } } } list+=request.getParameter("id")+","; //如果瀏覽記錄超過1000條，清零. String[] arr = list.split(","); if(arr!=null&&arr.length>0) { if(arr.length>=1000) { list=""; } } Cookie cookie = new Cookie("ListViewCookie",list); response.addCookie(cookie); %> -
