誰かがビットコインを特定のアドレスに送信するたびに、プログラムで検出したいと考えています。これは、この docker -compose.ymlファイルを使用して開始したローカル テストネットで発生します。
ローカル テストネットが実行されたら、次を使用して新しいアドレスを作成します
docker exec -it minimal-crypto-exchange_node_1 bitcoin-cli getnewaddress
返すとしましょう2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181。
このアドレスを次のJava コードに入れます。
import org.bitcoinj.core.Address;
import org.bitcoinj.core.Coin;
import org.bitcoinj.core.NetworkParameters;
import org.bitcoinj.core.Transaction;
import org.bitcoinj.wallet.Wallet;
import org.bitcoinj.wallet.listeners.WalletCoinsReceivedEventListener;
public class WalletObserver {
public void init() {
final NetworkParameters netParams = NetworkParameters.fromID(NetworkParameters.ID_REGTEST);
try {
final Wallet wallet = Wallet.createBasic(netParams);
wallet.addWatchedAddress(Address.fromString(netParams, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
wallet.addCoinsReceivedEventListener(new WalletCoinsReceivedEventListener() {
@Override
public void onCoinsReceived(final Wallet wallet, final Transaction transaction, final Coin prevBalance, final Coin newBalance) {
System.out.println("Heyo!");
}
});
}
catch (Exception exception) {
exception.printStackTrace();
}
}
}
次に、このクラスを使用して Java アプリケーションを開始します。
次に、テスト ビットコインを問題のアドレスに送信します。
% docker exec -it minimal-crypto-exchange_node_1 bitcoin-cli sendtoaddress 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181 0.5
068c377bab961356ad9a3919229a764aa929711c68aefd5dbd4c7c348eef3406
に行くとhttp://localhost:3002/tx/068c377bab961356ad9a3919229a764aa929711c68aefd5dbd4c7c348eef3406、取引の詳細が表示されます。
ただし、リスナー (onCoinsReceivedメソッド) のブレークポイントはアクティブになりません。
テスト BTC を送信するために使用するコードやコマンドを変更して、そのアカウントがお金を受け取るたびにonCoinsReceivedメソッドが呼び出されるようにするにはどうすればよいですか? Walletローカルホストに接続できる、またはNetworkParameters接続したい場所はありますか?
bitcoinj-core のバージョン 0.15.10 を使用しています。
更新 1:
docker-compose.ymlを変更し、次のポート マッピングを追加しました。
ports:
- "51001:50001"
- "51002:50002"
- "19001:19001"
- "19000:19000"
- "28332:28332"
次に、メソッドを書き直して、initlocalhost に接続してポートを指定できるようにしました。
public class WalletObserver {
public void init() {
final LocalTestNetParams netParams = new LocalTestNetParams();
netParams.setPort(50001);
try {
final WalletAppKit kit = new WalletAppKit(netParams, new File("."), "_minimalCryptoExchangeBtcWallet");
kit.setAutoSave(true);
kit.connectToLocalHost();
kit.startAsync();
kit.awaitRunning(); // I never get past this point
kit.peerGroup().addPeerDiscovery(new DnsDiscovery(netParams));
kit.wallet().addWatchedAddress(Address.fromString(netParams, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
kit.wallet().addCoinsReceivedEventListener(new WalletCoinsReceivedEventListener() {
@Override
public void onCoinsReceived(final Wallet wallet, final Transaction transaction, final Coin prevBalance, final Coin newBalance) {
System.out.println("Heyo!");
}
});
}
catch (Exception exception) {
exception.printStackTrace();
}
}
LocalTestNetParamsを使用すると、ポートを指定できます。
package com.dpisarenko.minimalcryptoexchange.logic.btc;
import org.bitcoinj.params.RegTestParams;
public class LocalTestNetParams extends RegTestParams {
public void setPort(final int newPort) {
this.port = newPort;
}
}
で前述のすべてのポートを試しましたnetParams.setPort(50001);。
いずれの場合も、の後に次のメッセージが表示されますkit.awaitRunning();。

更新 3:nodeエラーの原因は、私の Java コードで、実際の Bitcoin ノードではなく ElectrumX サーバーに接続しようとしたことだと思います ( docker-compose.yml)。
更新 4:
docker-compose.yml次のように変更しました。

更新 5:
誰かが (現在は削除されたコメントで) アプリケーションの出力に次のPeer does not support bloom filteringメッセージがあることを提案しました。
11:32:43.482 [NioClientManager] INFO org.bitcoinj.core.Peer - Peer{[127.0.0.1]:19000, version=70015, subVer=/Satoshi:0.19.1(bitcore)/, services=1033 (NETWORK, WITNESS, NETWORK_LIMITED), time=2021-11-06 11:32:43, height=4}: Peer does not support bloom filtering.
そこで、元のイメージをフォークし、bitcoin.confファイルを変更してブルーム フィルタリングを有効にしようとしました。
peerbloomfilters=1
実行するdocker build -t mentiflectax/bitcoind-custom-regtest:latest .と、次のエラー メッセージが表示されます (残りの出力の一部はここにあります)。
