我有一個Grails項目，我想用Bouncycastle來計算一個字符串的Sha512哈希。在Grails 2.5.0中找不到BouncyCastleProvider類
當我打電話Security.addProvider(new BouncyCastleProvider())我收到以下錯誤信息：

在我的IDE（的IntelliJ）進口import org.bouncycastle.jce.provider.BouncyCastleProvider似乎得到解決，我可以導航到類的位置。
爲什麼在執行應用程序時找不到BouncyCastle類？
OK，我才意識到我可以計算散列不添加BouncyCastle的作爲SecurityProvider ....但一個更不過，我仍然不明白，爲什麼我無法加載包含在Grails發行版中的類... – Tobson
