AutoUpdateCertificatesVerifier verifier = new AutoUpdateCertificatesVerifier(

        new WechatPay2Credentials(AppPayController.mchId, new PrivateKeySigner(AppPayController.mchSerialNo, merchantPrivateKey)),

        AppPayController.apiV3Key.getBytes("utf-8"));

报错

==============异常开始=============

java.lang.IllegalArgumentException: java.security.InvalidKeyException: Illegal key size

at com.wechat.pay.contrib.apache.httpclient.util.AesUtil.decryptToString(AesUtil.java:42)

at com.wechat.pay.contrib.apache.httpclient.auth.AutoUpdateCertificatesVerifier.deserializeToCerts(AutoUpdateCertificatesVerifier.java:138)

已按照网上说的 下载了UnlimitedJCEPolicyJDK8

解压后 覆盖掉了 jre1.8/lib/security 下面的local_policy.jar和US_export_policy.jar

可是并没有解决问题

实例化还是会出现这个报错 求帮助
