请高手帮忙看看getCurrentSession()的问题

代码:
package cn.oncat.dao.impl;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import cn.common.support.dao.impl.BaseDaoImpl;
import cn.oncat.dao.YonghuDao;
import cn.oncat.domain.Yonghu;
public class YonghuDaoImpl {
private SessionFactory sessionFactory;
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public void save(Yonghu yonghu){
getSessionFactory().openSession().save(yonghu);
}
}
为什么我用openSession就可以用getCurrentSession()就提示
