                                        }}
            ]

}

请查看上面的Stock.groovy文件，当我运行它时，出现了以下异常。请帮我解决这个问题。
URI /cses/json/stock
Class java.lang.IllegalArgumentException
Message null

有没有办法处理异常并检查出现故障值的条目。如果需要，我可以添加Oracle视图。

以下是堆栈跟踪：

更新 - 添加堆栈跟踪。
谢谢。

我不知道"有没有办法处理异常并检查出错值是什么"的意思。如果你能创建一个简单的示例应用，并将其发布到GitHub上，同时提供在应用中如何重现问题的说明，那几乎肯定会导致解决方案。 - Jeff Scott Brown
在Stock.groovy的第41行是什么？ - Charles Wood

显然，错误出现在你的类的第41行，我认为是：

params.id ? Stock.findAllByIdInList(params.id.split(",").collect { it as long }) : Stock.list(params)

你确定params.id是由逗号分隔的长整型字符串吗？
还要注意collect方法返回的是java.lang.Long列表，而不是你想要的原始类型long。为什么不尝试将Stock类的id属性改为java.lang.Long呢？（实际上，我建议总是使用包装类）。
