HarmonyOS 鸿蒙Next cryptoFramework中AES的CBC模式加密结果与java后端不一致

import { cryptoFramework } from ‘@kit.CryptoArchitectureKit’;
的AES加密方法时，使用了CBC模式，和java后端加密出来的结果不一样，也无法互相解密。我们的明文是“123456”，秘钥是“381ccb3658e1ef2bd182870221e5f01b”，java偏移量写的是16个0“0000000000000000”，鸿蒙端也是一个16位的都是0的数组，let arr = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0];
但是java后端加密出来的结果是“pXcp7U+XxCkJX1oj3qtjHQ==”，和网上各种AES加密工具加出来的一致，如
https://tool.lvtao.net/aes
https://www.ssleye.com/ssltool/aes_cipher.html
但是鸿蒙端加密出来的结果却是“SbTfhttrenx6rhBqpSVsRQ==”。
请问到底是哪里出了问题，是不是偏移量的问题？16个0的写法，是不是在鸿蒙里对应是这样写呢？谢谢解答！
代码如下：
