错误：com.sun.crypto.provider.AESCipher $ General无法转换为javax.crypto.CipherSpi

您好，我在Liferay dxp项目中使用Paytm校验和依赖性

但是我越来越 error :com.sun.crypto.provider.AESCipher$General cannot be cast to javax.crypto.CipherSpi

摇篮特性：

dependencies {compile fileTree(dir: 'libs/', include: '*.jar') compileInclude name: 'paytmchecksum-1.1'}

PaytmUtil包含以下代码。

private static String getCheckSumPayTm(TreeMap<String, String> reqMap){

    CheckSumServiceHelper checkSumServiceHelper =  CheckSumServiceHelper.getCheckSumServiceHelper();

    String checksum = null;
    try {
        checksum =  checkSumServiceHelper.genrateCheckSum("paytmKey", reqMap.toString());
        log.info("PAYTM CHECKSUM ================== "  + checksum);
    } catch (Exception e) {
        e.printStackTrace();
        log.error("error :" + e.getMessage());
    }
    return checksum;
}
