protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // 获得当前时间 Date date = new Date(); SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-ddhh:mm:ss");// 中间不能有空格 String currentTime = format.format(date); // 1.创建Cookie记录当前的最新访问时间 Cookie cookie = new Cookie("lastAccessTime", currentTime); cookie.setMaxAge(60 * 10 * 500); response.addCookie(cookie); // 2.获得客户端携带的cookie--lastAccessTime String lastAccessTime = null; Cookie[] cookies = request.getCookies(); if (cookies != null) { for (Cookie coo : cookies) { if ("lastAccessTime".equals(coo.getName())) { lastAccessTime = cookie.getValue(); } } } response.setContentType("text/html;charset=UTF-8"); if (lastAccessTime == null) { response.getWriter().write("你是第一次访问"); } else { response.getWriter().write("你上次的访问访问是:" + lastAccessTime); } }
解决办法:
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-ddhh:mm:ss");// 中间不能有空格
