SPRINGMVC two ways to access the session

Method One: Use Servlet-api

[Java]View PlainCopyprint?

2. @Controller
4. Public class Managercontroller {
8. @Resource
10. private ManagerService Managerserviceimpl;
14. @RequestMapping (value = "Manager/login.do", method = Requestmethod.get)
16. Public Modelandview Login (Managermodel managermodel,httpsession HttpSession) {
20. Managermodel manager = Managerserviceimpl.getmanager (Managermodel);
22. if (manager!=null) {
24. Manager.setpassword ("");
26. Httpsession.setattribute ("manager", manager);
28. return New Modelandview (new Redirectview (".  /admin/main.jsp "));
30. }else{
32. return New Modelandview (new Redirectview (".  /admin/login.jsp "));
34. }
36. }
40. @RequestMapping (value = "Manager/logout.do", method = Requestmethod.get)
42. Public String Logout (HttpSession HttpSession) {
44. Httpsession.getattribute ("manager");
46. return "Success";
48. }
50. }

Method Two: Use Sessionattributes

[Java]View PlainCopyprint?

2. @Controller
4. @SessionAttributes ("manager")
6. Public class Managercontroller {
10. @Resource
12. private ManagerService Managerserviceimpl;
16. @RequestMapping (value = "Manager/login.do", method = Requestmethod.get)
18. Public Modelandview Login (Managermodel managermodel,modelmap model) {
22. Managermodel manager = Managerserviceimpl.getmanager (Managermodel);
24. if (manager!=null) {
26. Manager.setpassword ("");
28. Model.addattribute ("manager", manager);
30. return New Modelandview (new Redirectview (".  /admin/main.jsp "));
32. }else{
34. return New Modelandview (new Redirectview (".  /admin/login.jsp "));
36. }
38. }
42. @RequestMapping (value = "Manager/logout.do", method = Requestmethod.get)
44. Public String Logout (@ModelAttribute ("manager") Managermodel Managermodel) {
46. return "Success";
48. }
50. }
