public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8"
);
String username= request.getParameter("username"
);
HttpSession session =
request.getSession();
session.setAttribute("username"
, username);
//request.setAttribute("username", username);//一定要保存,OGNL才能获取${username}
//或者直接在jsp页面中用<%=request.getParameter("username")获取,两种结果一样,但是后者有null
request.getRequestDispatcher("/success.jsp"
).forward(request, response);
//response.sendRedirect("/success.jsp");//会报错.原因不懂
