applicationContext.xml如下

hibernate.cfg.xml如下

实现类如下
package com.victor.dao.impl;
import java.util.ArrayList;
import java.util.List;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import com.victor.dao.IBaseDao;
import com.victor.entity.User;
public class BaseDaoImpl implements IBaseDao
{
private SessionFactory sessionFactory;
private Session session;
public void setSessionFactory(SessionFactory sessionFactory)
{
this.sessionFactory = sessionFactory;
}
@Override
public Session getSession()
{
return sessionFactory.getCurrentSession();
}
@Override
public List search(String hql)
{
User user = new User();
getSession().save(user);
List list = new ArrayList();
list = sessionFactory.getCurrentSession().createQuery(hql).list();
session.close();
return list;
}
@Override
public List searchBook(String hql)
{
List list = null;
list = sessionFactory.getCurrentSession().createQuery(hql).list();
session.close();
return list;
}
}报错如下
