我的弹簧控制器如下

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.oi.bean.User;

@Controller
public class BaseController {
    @Autowired
    private SessionFactory sessionFactory;

    @RequestMapping(value="/")
    public String getRespnse(Model m) {
        Session session =sessionFactory.getCurrentSession();
    //  List<User> usrLst=(List<User>) session.createQuery("from User");
    //  System.out.println("IN"+usrLst);
        return "home";
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

}

请帮忙.继续.. !!!
