但是我看了下语法没有问题啊，为什么会报错呢？求助!!!

[解决办法]
因为你前面的代码 有 {} 不匹配，初步目测是：

 if (request.getCookies() != null){
  for(Cookie cookie: request.getCookies()){
  if(cookie.getName().equals("account"))
  account = cookie.getValue();
  if(cookie.getName().equals("ssid"))
  ssid = cookie.getValue();
  }
 
 if(account != null && ssid != null){
  login = ssid.equals(calcMD5(account + KEY));
 }
%>
这段话的第一个 if 没有 右括号
[解决办法]
你看一下你的代码 最后一行有<%}%>
之前你的那半边括号没有
[解决办法]
}括号，建议你好好匹配一下。
