WEB 应用通常会引入 Session,用来在服务端和客户端之间保存一系列动作/消息的状态,比如网上购物维护 user 登录信息直到 user 退出。SpringMVC存取Session的两种方法,具体如下:
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"; } }
