import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.ui.ModelMap;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
import com.vaannila.dao.UserDAO;
import com.vaannila.domain.User;
public class UserController extends MultiActionController {
private UserDAO userDAO;
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
public ModelAndView add(HttpServletRequest request,
HttpServletResponse response, User user) throws Exception {
