 //得到用户提交的值 String name = request.getParameter("username"); String pwd = request.getParameter("passWord"); //创建HttpSessio对象 HttpSession s = request.getSession(); //将值绑定在session会话中 s.setAttribute("Sname",name); s.setAttribute("Spwd",pwd); //重定向 response.sendRedirect("yinyu.jsp");

在yinyu.jsp页面中得到值

//使用session会话取值

String username = (String)session.getAttribute("Sname"); String password = (String)session.getAttribute("Spwd");或者

${Sname}; ${Spwd};

 //得到用户提交的值 String name = request.getParameter("username"); String pwd = request.getParameter("password"); //将值绑定在request中 request.setAttribute("Rname",name); request.setAttribute("Rpwd",pwd); //页面转发 RequestDispatcher rd = request.getRequestDispatcher("yinyu.jsp"); rd.forward(request,response);

在yinyu.jsp页面中得到值

 //使用request协助相关取值

String username = (String)request.getAttribute("Rname"); String password = (String)request.getAttribute("Rpwd");或者${Sname};
