增加单测 java.lang.ClassCastException: com.sun.crypto.provider.RSACiphe

java.lang.ClassCastException: com.sun.crypto.provider.RSACipher cannot be cast to javax.crypto.CipherSpi

增加单测，对加密类进行单测时发现以上错误

byte[] keyBytes = Base64.decode(publicKey);
X509EncodedKeySpec x509KeySpec = new X509EncodedKeySpec(keyBytes);
KeyFactory keyFactory = KeyFactory.getInstance(KEY_ALGORITHM);
Key publicK = keyFactory.generatePublic(x509KeySpec);

}

  ClassCastException 肯定是类型不匹配了，但是功能可以正常执行，那就是类加载器的问题。
  网上搜索 增加  @PowerMockIgnore({"javax.management.*","javax.crypto.*"})   防止加载错类

  java.lang.ClassCastException: com.sun.crypto.provider.RSACipher cannot be cast to javax.crypto.CipherSpi

  

具体细节留下 回头研究下 为什么PowerMockIgnore加载错类
