如何连接bsc测试网络和本地主机:8545

Issue_description

这是我的装载合同代码

 PerformanceToken contract = PerformanceToken.load(
                this.contractAddress, web3j, transactionManager, new StaticGasProvider(this.gasPrice, DefaultGasProvider.GAS_LIMIT));

首先，我使用了草帽启动本地主机节点，我的配置是

web3j:
  enable: true
  nodeService: http://127.0.0.1:8545
  chainId: 31337

但它不能用扔

Disconnected from the target VM, address: '127.0.0.1:58999', transport: 'socket'

   boolean isSynced() throws Exception {
        EthSyncing ethSyncing = web3j.ethSyncing().send();
        if (ethSyncing.isSyncing()) {
            return false;
        } else {
            EthBlock ethBlock =
                    web3j.ethGetBlockByNumber(DefaultBlockParameterName.LATEST, false).send();
            long timestamp = ethBlock.getBlock().getTimestamp().longValueExact() * 1000;

            return System.currentTimeMillis() - syncThreshold < timestamp;
        }
    }

然后我转到bsc网络，这是我的配置

web3j:
  enable: true
  nodeService: https://data-seed-prebsc-1-s1.binance.org:8545
  chainId: 97

但它也不能用，特劳

        }
    }

我的错，我使用springboot yaml配置，0x开始字符串将转换为数字，所以这是我的配置错误，应该是

web3j:
  contractAddress: "0x81cE80b17eAddB5A9938461C07fd9F45c87B97d2"

不

web3j:
  contractAddress: 0x81cE80b17eAddB5A9938461C07fd9F45c87B97d2
