        } else {

        }

       count: { params -> if(params.code?.equals('gvt123')) {

             }else{ 
              0 
             }} 
      ] 

}

請查找上面的Stock.groovy文件，當我運行它時，我得到以下異常。請幫助我。Grails伊爾格爾論據異常

URI /cses/json/stock 
Class java.lang.IllegalArgumentException 
Message null

是否有任何處理異常的方法檢查哪些入口帶有故障值。如果需要我也可以添加Oracle視圖。

更新 - 添加堆棧跟蹤。
謝謝。

發佈完整的堆棧跟蹤 – injecteer

我不知道「有什麼辦法處理異常，檢查哪些入口帶有故障值。」手段。如果您可以創建一個簡單的示例應用程序並將其發佈到github以及如何在應用程序內重新創建問題的說明，那幾乎肯定會導致解決方案。 –

Stock.groovy的第41行是什麼？ –

顯然，錯誤的是你們班的41行，我認爲這是：

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

你肯定params.id是用逗號分隔多頭的字符串？

還請注意collect方法返回的是java.lang.Long的列表，而不是您想要的基元long。爲什麼不嘗試更改爲java.lang.Long以獲得Stock類的id屬性？（實際上，我建議始終使用包裝類）。
