Question

在我的私人测试区块链中使用web3j lib进行区块链交易时，我目前遇到标题响应错误： *资金不足*价格+价值*

我想转移一些以太网的帐户余额为10000以太。我退出的天然气价格的值为 18000000000 作为BigInt（它是WEI？），天然气限价是默认值从web3j使用的值 21000 。

所以问题是为什么我让交易不起作用？我想转移10以太：例如：

TransactionReceipt transactionReceipt = Transfer.sendFunds(web3, credentials, toAccount, BigDecimal.valueOf(10.0), Convert.Unit.ETHER).send();

genesis文件如下所示：

{
  "config": {
      "chainId": 9999,
      "homesteadBlock": 0,
      "eip155Block": 0,
      "eip158Block": 0,
      "byzantiumBlock": 0
   },
   "difficulty": "400",
   "gasLimit": "2100000",
   "alloc": {
      "0x9b6301bf2cfe11066dbd641f91a2b82e0783130e": { 
          "balance": "100000000000000000000000" 
      }
   }
}

代码如下所示：

// create new account 
Admin admin = Admin.build(new HttpService());
NewAccountIdentifier newAccount = admin.personalNewAccount("PASSWORD").send();

// get current created account
Web3j web3 = Web3.build(new HttpService());
EthAccounts accounts = web3.ethAccounts().send();
String lastAccount = Iterables.getLast(accounts.getAccounts());
// get creadentials for the first account having some ether
String firstAccount = web3.ethAccounts().send().getAccounts().get(0);
Credentials credentials = Credentials.create(firstAccount);

// get current balance for first account
EthGetBalance balance = admin.ethGetBalance(firstAccount, DefaultBlockParameterName.LATEST).send();
BigDecimal balanceVaue = Convert.fromWei(balance.getBalance().toString(), Convert.Unit.ETHER);

// create transaction to give the new created account some ether from the first one
// log some stuff
System.out.println("Account: " + firstAccount);
System.out.println("Account balance: " + balanceVaue);
System.out.println("Gas Price admin.ethGasPrice() in Ether: " + Convert.fromWei(gasPrice.toString(), Convert.Unit.ETHER));
System.out.println("Transfer Gas Limit in Ether: " + Convert.fromWei(Transfer.GAS_LIMIT.toString(), Convert.Unit.ETHER));
System.out.println("Transfer Gas Price in Ether: " + Convert.fromWei(Transfer.GAS_PRICE.toString(), Convert.Unit.ETHER));

TransactionReceipt transactionReceipt = Transfer.sendFunds(web3, credentials, lastAccount, BigDecimal.valueOf(10.0), Convert.Unit.ETHER).send();
String transactionHash = transactionReceipt.getTransactionHash();

这导致上述交易错误：天然气资金不足*价格+价值

以下是日志记录输出：

您的Credentials对象不正确。您正在使用的方法是期望私钥，而不是以太坊地址。

Credentials credentials = Credentials.create(firstAccount);

应该是

Credentials credentials = Credentials.create("<PRIVATE_KEY_HERE>");

Web3j Transfer.sendFunds（）返回错误＆＃34;资金不足*价格+价值＆＃34;
