@Controller@RequestMapping(value="/user")public class UserAction{ ???@RequestMapping(value="/add",method=RequestMethod.POST) ???public void add(HttpServletRequest request,HttpServletResponse response) throws Exception{ ???????System.out.println("HelloAction::add()::POST"); ???????int id = Integer.parseInt(request.getParameter("id")); ???????String name = request.getParameter("name"); ???????double sal = Double.parseDouble(request.getParameter("sal")); ???????System.out.println(id + ":" + name + ":" + sal); ???????request.getSession().setAttribute("id",id); ???????request.getSession().setAttribute("name",name); ???????request.getSession().setAttribute("sal",sal); ???????response.sendRedirect(request.getContextPath()+"/register.jsp"); ???} ???}
