如下代码所示：多表联查，pojo类中标识@Readonly的字段在表中没有，但在该方法的结果集中有，每次项目启动后提示找不到字段，这种情况如何合理的处理：

	public List<LatestTrendst> list(){
		Sql sql = Sqls.create("select a.res_id,a.act,a.create_time,b.res_title, b.res_type_name,c.user_name,c.user_icon from (select * from yb_latest_trendst order by create_time desc limit 3) as a left join res_info_view b on a.res_id = b.res_id left join user_param_view c on a.user_id = c.user_id");
		sql.setCallback(Sqls.callback.entities());
		sql.setEntity(this.dao().getEntity(LatestTrendst.class));
		this.dao().execute(sql);
		return sql.getList(LatestTrendst.class);
	}
