Java RSA解密错误BadPaddingException

我用对称密钥（AES）加密文件，然后用rsa密钥加密密钥。 加密工作正常，但在解密过程中会出现错误： 以下是stacktrace：

我什么都试过了，请帮帮我，谢谢

@RequestMapping(value= "/{userId}/uploadresource/{userEmail:.*}", method = RequestMethod.POST )

    Users senderUser= userService.getUserById(UserId);
    int receiverUserId = recieverUser.getUser_id();
    Profile receiverProfile = userService.getUserProfile(receiverUserId);
    byte[] receiverPublicKey=receiverProfile.getPublicKey();

    KeyGenerator keyGen = KeyGenerator.getInstance("AES");
    keyGen.init(192); // for example
    SecretKey secretKey = keyGen.generateKey();

    byte[] secretKeyEncoded= secretKey.getEncoded();

    Cipher cipher = Cipher.getInstance("AES");
    cipher.init(Cipher.ENCRYPT_MODE, secretKey);
    byte[] cipherData = cipher.doFinal(file.getBytes());

    Cipher cipher1 = Cipher.getInstance("RSA/ECB/PKCS1Padding");
    cipher1.init(Cipher.ENCRYPT_MODE, testPubKey);
    byte[] aesKeyEncryptedBytes = cipher.doFinal(secretKeyEncoded); 


    String senderUserName= senderUser.getUser_email();          
    AsymetricSharing sharing= new AsymetricSharing();

    sharing.setReceiverId(receiverUserId);
    sharing.setResourceFile(cipherData);
    sharing.setResourceName(file.getOriginalFilename());
    sharing.setSenderId(senderUser.getUser_id());
    sharing.setSenderName(senderUserName);
    sharing.setSymetricKey(aesKeyEncryptedBytes);

    resourseService.uploadAsymmetricResource(sharing);      
    //resources=this.resourseService.GetResourcesInGroup(group_id);     
}

它在解密中没有填充RSA（如RSA/ECB/NoPadding）。尝试将其更改为与加密中相同的值（“RSA/ECB/PKCS1Padding”）。RSA加密值也可以取消添加，如果我不清楚，请原谅我的英语：/

您检查了什么？对称键值？密码的输入/输出？请注意，SO不是社区调试器。

Cipher cipher = Cipher.getInstance("RSA");
