今天在做cookie部分的demo的时候出现了一个错误Servlet部分的代码如下

1      Date data=new Date();
     2     SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
     3     String Last = format.format(data);
     4     // System.out.println(Last);
     5      
     6     Cookie cookie =new Cookie("Lastname",Last);
     7     cookie.setMaxAge(60*10*500);
     8     response.addCookie(cookie);
     9     //获得用户携带的cookie
    10     String last=null;
    11     Cookie[] cookies = request.getCookies();
    12     if(cookies!=null){
    13     for(Cookie coo:cookies){
    14     if("Lastname".equals(coo.getName())){
    15     last = coo.getValue();
    16      
    17     }
    18     }
    19     }
    20      
    21     response.setContentType("text/html;charset=utf-8");
    22     if(last==null){
    23      
    24     response.getWriter().write("您是第一次访问");
    25     }else{
    26     response.getWriter().write("你上次访问的时间为"+last);
    27     }

再访问该Servlet的时候页面就为500，并报异常An invalid character \[32\] was present in the Cookie value，

后来发现32对应的编码是空格，后来发现

1.  SimpleDateFormat format=newSimpleDateFormat("yyyy-MM-dd hh:mm:ss");代码中产生了空格，后改为

1.  SimpleDateFormat format=newSimpleDateFormat("yyyy-MM-dd-hh:mm:ss");就可正常访问了
