我正在使用命令./byfn.sh up -l java -a运行HLF 1.4.4的BYFN网络（因为我需要证书颁发机构）。
然后我按如下方式运行客户端网关实现：
public static void main(String[] args) throws IOException {
Path walletDirectory = Paths.get("wallet");
Wallet wallet = Wallet.createFileSystemWallet(walletDirectory);
Path networkConfigFile = Paths.get("config","byfn","connection-org1.json");
Gateway.Builder builder = Gateway.createBuilder()
.identity(wallet, "myuser")
.networkConfig(networkConfigFile);
try (Gateway gateway = builder.connect()) {
Network network = gateway.getNetwork("mychannel");
Contract contract = network.getContract("mycc");
byte[] createProductResult = contract.submitTransaction("init","ann","100","bob","200");
System.out.println(new String(createProductResult, StandardCharsets.UTF_8));
} catch (ContractException | TimeoutException | InterruptedException e) {
e.printStackTrace();
}
}
我收到以下异常：
log4j:WARN No appenders could be found for logger (org.hyperledger.fabric.sdk.helper.Config).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
