SpringMVC存取Session的两种方法

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";
}
}

@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{

@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);

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){
