Hibernate编写通用数据库操作代码演示

    }
    t.commit();
    HibernateSessionFactory.clossSession();
}

update方法
public void update(Object o,Serializable id){
    Session session = HibernateSessionFactory.currentSession();
    Transaction t = session.beginTransaction();
    session.update(o,id);
    t.commit();
    HibernateSessionFactory.clossSession();
}

基于HQL的通用select方法
public ArrayList select(String sql){
    Session session = HibernateSessionFactory.currentSession();
    Query query = createQuery(sql);
    List list = query.list();
    HibernateSessionFactory.clossSession();
    return (ArrayList)list;
}
