Cannot find any provider supporting SM4问题记录

1. 问题场景
   使用SM4加密异常

2. 异常信息

 java.security.NoSuchAlgorithmException: Cannot find any provider supporting SM4at javax.crypto.Cipher.getInstance(Cipher.java:539) ~[na:1.8.0_191]at cn.hutool.crypto.SecureUtil.createCipher(SecureUtil.java:1027) ~[hutool-all-5.6.3.jar:na]at cn.hutool.crypto.symmetric.SymmetricCrypto.init(SymmetricCrypto.java:164) ~[hutool-all-5.6.3.jar:na]at cn.hutool.crypto.symmetric.SymmetricCrypto.<init>(SymmetricCrypto.java:134) ~[hutool-all-5.6.3.jar:na]at cn.hutool.crypto.symmetric.SymmetricCrypto.<init>(SymmetricCrypto.java:122) ~[hutool-all-5.6.3.jar:na]at cn.hutool.crypto.symmetric.SymmetricCrypto.<init>(SymmetricCrypto.java:111) ~[hutool-all-5.6.3.jar:na]

3. 原因
   jdk缺少jar包（bcprov-jdk15to18-1.68）支持
4. 处理
   maven下载jar包保存到jdk安装目录中的jre\lib\ext，以本地为例存放目录为

C:\Program Files\Java\jdk1.8.0_191\jre\lib\ext
