【问题描述】：

我已经尝试了一切： 我已按照本教程进行操作：How to create a BKS (BouncyCastle) format Java Keystore that contains a client certificate chain

我仍然收到 Class not found 异常请帮助。

这是我的 java.security 中的提供程序：

security.provider.1=sun.security.provider.Sun
security.provider.2=org.bouncycastle.jce.provider.BouncyCastleProvider
security.provider.3=sun.security.rsa.SunRsaSign
security.provider.4=sun.security.ec.SunEC
security.provider.5=com.sun.net.ssl.internal.ssl.Provider
security.provider.6=com.sun.crypto.provider.SunJCE
security.provider.7=sun.security.jgss.SunProvider
security.provider.8=com.sun.security.sasl.Provider
security.provider.9=org.jcp.xml.dsig.internal.dom.XMLDSigRI
security.provider.10=sun.security.smartcardio.SunPCSC
security.provider.11=apple.security.AppleProvider

【问题讨论】：

这个问题可能重复吗？ ***.com/questions/19505042/…

Rob 老兄，我已经锁定了这个问题，但它并没有解决我的问题

我想我不会使用 Bouncy Castle 而是使用 Java 附带的标准密钥库

我终于重新阅读了堆栈跟踪。 ClassNotFoundException 非常具有误导性。请注意，实际上根本原因是 ClassCastException。因此，类路径甚至 java.security 的配置都不是问题。相反，问题必须与sslImplementationName 设置有关。

好的，那我该怎么办，你有什么解决办法吗？

【参考方案1】：

从您包含的链接尝试替换

Security.addProvider(new BouncyCastleProvider());

通过

Security.insertProviderAt(new BouncyCastleProvider(), 1); 
//  The position is 1-based, that is, 1 is most preferred, followed by 2, and so on.

确保 BC 优于 Sun Provider
