org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation
of non-transactional one here

错误重现：

public class BaseDaoImpl<T,PK extends Serializable> extends HibernateDaoSupport implements IBaseDao<T,PK>{

private Session getCurrentSession() {

return this.getHibernateTemplate().getSessionFactory().getCurrentSession();

}

public Serializable save(T o) {

return this.getCurrentSession().save(o);

}
}

调用save时 报错。

解决方案：
return this.getCurrentSession().save(o); 改成
return this.getHibernateTemplate().save(o);
