WEB applications usually introduce Session to save a series of actions/message status between the server and the client, such as online shopping to maintain user login information until user logs out. There are two methods of SpringMVC accessing Session, as follows:
Method 1: Use 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(new RedirectView("../admin/login.jsp")); } } @RequestMapping(value = "manager/logout.do",method = RequestMethod.GET) public String logout(HttpSession httpSession){ httpSession.getAttribute("manager"); return "success"; } } Method 2: Use 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"; } }The above is all the content of this article.
