                "GROUP BY alternative_ids "+
            ") AS temp";

    SQLQuery sqlQuery = getSQLQuery(sqlStr);
    System.out.println("ADCAMP SQL ===============> " + sqlStr);
    List<Object[]> result = new ArrayList<Object[]>();

    return sqlQuery.list();
}

这是一个有点复杂的sql，我是使用params创建它的，当我在行sqlQuery.list();上运行它时会出现这个错误：

然而，当我在查询浏览器中的sql查询上运行脚本时，它无例外地工作并返回结果。

SQL是：

SELECT adcamp_id, alternative_ids, click, orderCount, conversion, (100*orderCount)/click AS conversionRate, (click * 1.0) AS cost 
FROM ( SELECT adcamp_id, alternative_ids, COUNT(*) AS click, 
   SUM(( SELECT COUNT(*) FROM nc_order, nc_cart WHERE nc_order.cart_id = nc_cart.id AND nc_cart.adcamp_click_id = nc_adcamp_click.id AND nc_order.order_status = 'delivered'  )) AS orderCount, 
   SUM(( SELECT SUM(nc_payment_log.amount) FROM nc_order, nc_cart, nc_payment_log WHERE nc_order.payment_log_id = nc_payment_log.id AND nc_order.cart_id = nc_cart.id AND nc_cart.adcamp_click_id = nc_adcamp_click.id AND nc_order.order_status = 'delivered'  )) AS conversion 
   FROM nc_adcamp_click 
   WHERE adcamp_id =1 AND date_clicked BETWEEN '2013-02-09' AND '2013-05-09' 
   GROUP BY alternative_ids 
) AS temp

我认为你的问题可能与此有关：

https://hibernate.atlassian.net/browse/HHH-6681

查看此本机查询的堆栈跟踪中的StandardQueryCache很奇怪。您是否明确为此查询启用了查询缓存？如果是这样，请尝试使用无查询缓存，因为看起来hibernate在导出映射实体的类型以将缓存绑定到的问题上存在问题。

Hibernate获取SQL query.list（）：ArrayIndexOutOfBoundsException 0
