Question

我是使用Java进行智能合约的首次用户，我通常会使用JS。我正在IntelliJ上进行开发，并已设法将Solidity合同编译为Java包装器类。除非我尝试部署合同，否则一切运行正常。它一直说没有足够的资金来进行交易。我使用WalletUtils生成了一个.json文件，我以为这将充当我的钱包，但其中没有提及电量或余额。这些属性也与带有JS的常规genesis.json文件完全不同。我是否认为需要在此文件或天平中添加一些气体？

Web3j web3 = Web3j.build(new HttpService(<Infura endpoint>));

System.out.println("Connected to Ethereum client version: "
                + web3.web3ClientVersion().send().getWeb3ClientVersion());

// This generated the .json file:
WalletUtils.generateNewWalletFile(<password>, new File(""), true);


Credentials credentials =
                WalletUtils.loadCredentials(
                        <password>,
                        <jsonfile>);
        System.out.println("Credentials loaded");

ContractGasProvider contractGasProvider = new DefaultGasProvider();

// Errors at this stage:
RoverMoves contract = RoverMoves.deploy(web3, credentials, contractGasProvider).send();

生成的.json文件如下：

{"address":"c6886a803746be0caee10de1acb165447b64f99e",
"id":"5b3b1932-e4f9-48fd-97bd-0d2845b07147","version":3,
