UserDao
public interface UserDao {
User findUserByUserName(String username);
}
UserService
@Service
public class UserService implements IUserService {
@Autowired
private UserDao userDao;
@Override
public boolean login(String username, String password) {
User user = userDao.findUserByUserName(username);
if (user != null && user.getPassword().equals(password)){
return true;
}else{
return false;
}
}
}
IUserService
public interface IUserService {
boolean login(String username, String password);
}
UserController
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService userService;
@RequestMapping("/login.do")
public ModelAndView login(User user){
boolean flag = userService.login(user.getUsername(),user.getPassword());
ModelAndView modelAndView = new ModelAndView();
if (flag){
modelAndView.setViewName("./ok");
}else{
modelAndView.setViewName("./failure");
}
return modelAndView;
}
}
