在Windows上使用ColdFusion 9.0.1我遇到了以下問題。將二進制數據反序列化爲對象時出現StackOverflowError
我有一些相當大和複雜的對象（嵌套對象與嵌套對象與嵌套對象...等）序列化爲二進制數據，所以我可以把它放到我的數據庫。這就像一個魅力，但是當我從數據庫中檢索這樣的二進制數據，然後嘗試使用objectLoad()功能反序列化數據，我得到一個堆棧overlfow錯誤：

沒有無限循環或任何東西，因爲當我在JVM設置中增加堆棧大小時，它一切正常。但我不想在生產服務器上增加我的堆棧大小。
那麼有沒有人知道一種方法來反序列化二進制數據到對象而不創建如此龐大的堆棧？
創建一個嵌套較少的對象結構。嵌套層次反映了對象結構的複雜性。如果你有一個像樹的集合，你可以編寫自己的自定義序列化，它可以優化數據如何遍歷。這個最簡單的解決方案可能是增加最大堆棧大小。 – 2012-04-18 09:40:57
我知道，但數據已經在您看到的數據庫中。 – 2012-04-18 09:43:37
在這種情況下，您需要更大的堆棧來讀取數據。我很驚訝你能寫出對象，因爲通常你需要大約相同的堆棧大小。 – 2012-04-18 09:46:30
