源码：

import cn.hutool.crypto.SmUtil;
import cn.hutool.crypto.symmetric.SymmetricCrypto;
public class SM4Helper2 {
//key必须是16字节，即128位
final static String key = "8464288604b7fc85";
//指明加密算法和秘钥
static SymmetricCrypto sm4 = new SymmetricCrypto("SM4/ECB/PKCS5Padding", key.getBytes());
// static SymmetricCrypto sm4 = SmUtil.sm4(key.getBytes());
//加密为16进制，也可以加密成base64/字节数组
public static byte[] encryptSm4(byte[] data) {
byte[] encrypt = sm4.encrypt(data);
return encrypt;
}
//解密
public static byte[] decryptSm4(byte[] data) {
byte[] decrypt = sm4.decrypt(data);
return decrypt;
}
}


解决办法：
maven应用的包版本不对：
bc包需要1.69版本的，下面这组坐标可以解决这个问题。
