WEB applications usually introduce Session to save the status of a series of actions/messages between the server and the client. For example, online shopping maintains user login information until the user exits. There are two methods for SpringMVC to access 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("../admin/login.jsp")); 
    } 
  } 
    
  @RequestMapping(value = "manager/logout.do",method = RequestMethod.GET) 
  public String logout(HttpSession httpSession){ 
    httpSession.getAttribute("manager"); 
    return "success"; 
  } 
}
Copy after login

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"; 
  } 
}
Copy after login
