在使用web3j进行以太坊智能合约写操作时遇到`ArrayIndexOutOfBoundsException`错误。问题源于使用了无效的私钥签署交易。确保私钥和地址的有效性，参考以太坊常见问题和错误进行排查。此外，推荐了针对不同编程语言的以太坊开发教程。

web3j:智能合约写操作时总是抛出java.lang.ArrayIndexOutOfBoundsException错误，不知道什么问题。

我的代码如下：

String hexPrivateKey = String.format("%040x", new BigInteger(1, Config.privateKey.getBytes()));
String hexPublicKey = String.format("%040x", new BigInteger(1, Config.publicKey.getBytes()));
Credentials credentials = Credentials.create(hexPrivateKey, hexPublicKey);
DataSaver contract = DataSaver.load(
address, web3j, credentials, Contract.GAS_PRICE, Contract.GAS_LIMIT);

RemoteCall transaction2 = contract.updateDocumentPayload(
BigInteger.valueOf(1), "Test");
transaction2.send();

读取操作是成功的。写入返回以下错误：
