SpringMVC存取Session的兩種方法

WEB 應用通常會引入Session，用來在服務端和客戶端之間保存一系列動作/消息的狀態，比如網上購物維護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

 @Controller public 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"; } }

方法二：使用SessionAttributes

 @Controller @SessionAttributes("manager") public class ManagerController { @Resource private ManagerService managerServiceImpl; @RequestMapping(value = "manager/login.do",method = RequestMethod.GET) public ModelAndView login(ManagerModel managerModel,ModelMap model){ ManagerModel manager = managerServiceImpl.getManager(managerModel); if(manager!=null){ manager.setPassword(""); model.addAttribute("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(@ModelAttribute("manager")ManagerModel managerModel){ return "success"; } }
