 原因：

在Java的核心類庫中有一個JCE（Java Cryptography Extension），JCE是一組包，它們提供用于加密、密鑰生成和協商以及 Message Authentication Code（MAC）算法的架構和實作，是以這個是實作加密解密的重要類庫。

JRE中自帶的“local_policy.jar ”和“US_export_policy.jar”是支援128位密鑰的加密算法，而當我們要使用256位密鑰算法的時候，已經超出它的範圍，無法支援，秘鑰長度不能滿足需求，是以才會報：“java.security.InvalidKeyException: Illegal key size or default parameters”的異常。

解決方案：

替換無限制秘鑰長度的jar包，替換自身jdk自帶的jar包local_policy.jar和US_export_policy.jar
