顶头引用了HttpSession
doPost HttpSession hs =new HttpSession();
最后一段报错“can't instantiate the type HttpSession”
该怎么正确使用session?!
doPost HttpSession hs =new HttpSession();
最后一段报错“can't instantiate the type HttpSession”
该怎么正确使用session?!
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
//通过request得到session
request.getSession().setAttribute(arg0, arg1);
}
request.getSession();
HttpSession hs =new HttpSession();
hs.setAttribute(key, value);
