@WebServlet("/newSession")
public class NewSession extends HttpServlet {

    protected void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
        response.setCharacterEncoding("utf-8");
        response.setHeader("Content-type", "text/html;charset=utf-8");
        PrintWriter out = response.getWriter();
        
        out.println("测试Session属性<br/><br/>");
        
        HttpSession session = request.getSession();
        if (session.isNew()) {
            out.println("新朋友<br/><br/>");
        } else {
            out.println("欢迎回来<br/><br/>");
