스프링 session 기반 로그인 화면 구현 본문
* session & cookie 게시물과 연관
spring 프로젝트로 구조는 다음과 같다.
UserController.java
@Controller
public class UserController {
//로그인 화면
@RequestMapping("/login")
public String login() {
System.out.println("==== loginPage Start ====");
return "login";
}
// 로그아웃
@RequestMapping("logout")
public String logout(HttpSession session) {
session.setAttribute("userLoginInfo", null);
return "redirect:login";
}
@Inject
private UserService userService;
private static final Logger logger = LoggerFactory.getLogger(UserController.class);
@RequestMapping(value = "page2", method = RequestMethod.POST)
public ModelAndView loginCheck(MemberVO vo, HttpServletRequest req, HttpSession session, RedirectAttributes rttr) throws Exception{
ModelAndView mav = new ModelAndView();
mav.setViewName("redirect:login");
MemberVO loginUser = userService.login(vo);
rttr.addFlashAttribute("msg", false);
if(loginUser != null){
session.setAttribute("userLoginInfo", loginUser);
}
return mav;
}
}page2 관련 컨트롤러 생성 시
@RequestMapping("page2")
public String page2(){
return "page2";
}
추가
UserDao.java
@Repository("UserDAO")
public class UserDAO {
@Autowired
@Resource(name = "sqlSessionTemplate")
private SqlSession sqlSessionFactory;
public MemberVO login(MemberVO vo) throws Exception{
return sqlSessionFactory.selectOne("com.sample.mysql.selectLoginInfo", vo);
}
}UserService.java
public interface UserService {
public MemberVO login(MemberVO vo)throws Exception;
}
UserServiceImpl.java
@Service("UserService")
@Repository
public class UserServiceImpl implements UserService{
@Resource(name="UserDAO")
private UserDAO userDAO;
@Override
public MemberVO login(MemberVO vo)throws Exception{
return userDAO.login(vo);
}
}
MemberVO.java
public class MemberVO {
private String userCd;
private String userPs;
public String getUserCd() {
return userCd;
}
public void setUserCd(String userCd) {
this.userCd = userCd;
}
public String getUserPs() {
return userPs;
}
public void setUserPs(String userPs) {
this.userPs = userPs;
}
}
