以前都是用openSession或者getCurrentSession的方法操作数据库，今天了解到有这种方法，试验了下，但报错了
public class BaseDaoHibernateImp extends HibernateDaoSupport{
protected List getList(final String hql){
return this.getHibernateTemplate().executeFind(new HibernateCallback() {
public Object doInHibernate(Session session)
throws HibernateException, SQLException {
Query query = session.createQuery(hql);
List list = query.list();
return list;
}
});
//return this.getHibernateTemplate().find(hql);
}
}
BaseDaoHibernateImp.java这个类里面也没有写其他的方法了。
然后
public class StudentDaoImp extends BaseDaoHibernateImp implements StudentDao{
@SuppressWarnings("unchecked")
public List<Student> findAll() {
List<Student> students = new ArrayList<Student>();
final String hql = "from Student";
students = this.getList(hql);
return students;
}
}
然后运行报错

我在想 是不是 什么地方少配置了什么？或者少写了什么地方？我试了下 用 原来经常用的sessionFactory.openSession()这个方法能成功查询出结果来。但是为什么这个不行呢？
求解答。
------解决思路----------------------
hibernate jar版本的问题吧
