Question

private static final Web3j web3j = Web3j.build(new HttpService("https://ropsten.infura.io/v3/d11459c1c17049628f462a1492c7df36"));

private static final Credentials hostCredentials = Credentials.create("666A82FC33F8134577A7BEB1BDEAA689BB72740178727691D63032432B83E0FB");

private static final BigInteger gasLimit = BigInteger.valueOf(6721975L);
private static final BigInteger gasPrice =  BigInteger.valueOf(2000000000000L);

在连接Ropsten之前，ganache已被链接。

Gaslimits和Gasprices是当时使用的来自ganache的信息。

但是，当我第一次连接到Ropsten时，标题没有错误。

 public String depart_wallet(String code) {
        String walletCode = "";
        switch(code) {
            case "ct_01" : 
                    walletCode = "83E094366642F531189D56DF33AC870DB53AF8C7F7F60A7A8B20CB85BC43A59F";
                    break;
            case "ft_01" :

    public void budgetAdd(HttpServletRequest req, Model model) throws Exception {

        String department_code = req.getParameter("dept_code");

        String deptWallet = depart_wallet(department_code);

        Credentials dept_AccountNumber = Credentials.create(deptWallet);

        System.out.println(gasPrice);
        System.out.println(gasLimit);

        **String contractAddress2 = Materal.deploy(web3j, dept_AccountNumber, gasPrice, gasLimit).send().getContractAddress();**
    }

  

insufficient funds for gas * price + value

运行Service deploy()我遇到了。

您是否可以向我解释是否有人对此错误有任何了解？

使用方法deploy()时主题发生错误。
