public int find2(String hql){
		final String hql1 = hql;
		 try{
			this.getHibernateTemplate().execute(new HibernateCallback(){
				//执行查询操作
				public Object doInHibernate(Session session)
						throws HibernateException, SQLException {
					list = session.createQuery(hql1).list();
					return list;
				}				
			});			
			int num=(Integer) list.get(0);
			return num;
