Orm 未设置Ebean/IDI参数

我和埃宾有个奇怪的问题

代码：

我不明白为什么tfzIds列表没有被插入到EBean构建的查询中

---

我尝试的是：我将强制转换添加到long，以确保列表中不会出现空值。但这似乎不是问题所在，列表似乎根本没有被读取。

发生异常是因为

行

为空。。。我很惊讶埃宾没有检查。我通过断言rows

hasNext（）

作为该方法的第一个语句来解决这个问题，从而引发了一个更有用的异常。

这并不能回答这个问题。若要评论或要求作者澄清，请在其帖子下方留下评论。@pktangyue:为什么不？“我问了这个问题，所以肯定，我必须知道吗？”JanusTroelsen非常感谢，这让我发疯，我在其他地方搜索。我把这叫做埃宾虫。
