jsp写入cookie中文出现乱码的解决办法

第一步：写入cookie时先进行编码

            Cookie cookie=new Cookie("groupMembersList",URLEncoder.encode  (groupMembersList,"GBK"));                                         //默认为临时Cookie,MaxAge<0
         //cookie.setMaxAge(-1);
        response.addCookie(cookie);

 

第二步：读取cookie再进行解码

       <%
             Cookie[] cookies=request.getCookies();
             for(Cookie cookie:cookies){
                    if(cookie.getName().equalsIgnoreCase("groupMembersList"))
             request.setAttribute("group",URLDecoder.decode(cookie.getValue(),"GBK"));   
            }
      %>

     <c:out value="${requestScope.group }"/>
