WEB 應(yīng)用通常會引入 Session，用來在服務(wù)端和客戶端之間保存一系列動作/消息的狀態(tài)，比如網(wǎng)上購物維護(hù) user 登錄信息直到 user 退出。SpringMVC存取Session的兩種方法，具體如下：
方法一：使用servlet-api

@Controllerpublic class ManagerController { @Resource private ManagerService managerServiceImpl; @RequestMapping(value = "manager/login.do",method = RequestMethod.GET) public ModelAndView login(ManagerModel managerModel,HttpSession httpSession){ ManagerModel manager = managerServiceImpl.getManager(managerModel); if(manager!=null){ manager.setPassword(""); httpSession.setAttribute("manager", manager); return new ModelAndView(new RedirectView("../admin/main.jsp")); }else{ return new ModelAndView(new RedirectView("../admin/login.jsp")); } } @RequestMapping(value = "manager/logout.do",method = RequestMethod.GET) public String logout(HttpSession httpSession){ httpSession.getAttribute("manager"); return "success"; } } |
