SpringMVC存取Session的两种方法
作者：南蛮虫
Spring MVC是个非常优秀的框架,本篇文章主要介绍了SpringMVC存取Session的两种方法，具有一定的参考价值，有兴趣的可以了解一下。
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";
}
}
