查找NotSerializedException的原因：java.util.ArrayList$SubList

问题描述 投票：0回答：1

我正在使用 redisson 来保存我的应用程序的会话。该应用程序使用 JSF 2.3。 我试图找到 NotSerialized 异常的原因，但该应用程序仅记录 redisson 堆栈。基本上它并不指向生成子列表的代码。

我已经检查过，我的代码没有任何子列表，所以我想知道如何找到问题的根源？

这是日志：

从 

arrayList.subList()
返回的列表不是 
Serializable
。搜索您的代码库并确保您和您正在使用的任何框架或库都没有调用该方法。

要查找，请在 IDE 中对 

subList()
的 
ArrayList
元素使用“查找用法”功能。希望这是您的代码，而不是您需要修补的第三方代码。

要修复，只需从结果创建一个新的可序列化列表：

... = new ArrayList<>(myList.subList());
