SpringMVC存取Session的两种方法
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
publicclassManagerController{
@Resource
privateManagerServicemanagerServiceImpl;
@RequestMapping(value="manager/login.do",method=RequestMethod.GET)
publicModelAndViewlogin(ManagerModelmanagerModel,HttpSessionhttpSession){
ManagerModelmanager=managerServiceImpl.getManager(managerModel);
if(manager!=null){
manager.setPassword("");
httpSession.setAttribute("manager",manager);
returnnewModelAndView(newRedirectView("../admin/main.jsp"));
}else{
returnnewModelAndView(newRedirectView("../admin/login.jsp"));
}
}
@RequestMapping(value="manager/logout.do",method=RequestMethod.GET)
publicStringlogout(HttpSessionhttpSession){
httpSession.getAttribute("manager");
return"success";
}
}
方法二：使用SessionAttributes
@Controller
@SessionAttributes("manager")
publicclassManagerController{
@Resource
privateManagerServicemanagerServiceImpl;
@RequestMapping(value="manager/login.do",method=RequestMethod.GET)
publicModelAndViewlogin(ManagerModelmanagerModel,ModelMapmodel){
ManagerModelmanager=managerServiceImpl.getManager(managerModel);
if(manager!=null){
manager.setPassword("");
model.addAttribute("manager",manager);
returnnewModelAndView(newRedirectView("../admin/main.jsp"));
}else{
returnnewModelAndView(newRedirectView("../admin/login.jsp"));
}
}
@RequestMapping(value="manager/logout.do",method=RequestMethod.GET)
publicStringlogout(@ModelAttribute("manager")ManagerModelmanagerModel){
return"success";
}
}
