1、首先要安裝好bitcoin core服務 上一篇有怎么安裝

下面代碼支持多錢包多地址動態調用，但讓我沒用使用多地址，根據自己的需要然后封裝方法就好

2、引入jar? JavaBitcoinRpcClient

<!-- https://mvnrepository.com/artifact/wf.bitcoin/JavaBitcoindRpcClient --> <dependency><groupId>wf.bitcoin</groupId><artifactId>JavaBitcoindRpcClient</artifactId><version>1.0.0</version> </dependency>

?

3、 BitcoinRPC 接口

package com.lpz.btc.api;import com.lpz.btc.model.TransferModel;public interface BitcoinRPC {/*** 創建BTC錢包地址(錢包、地址都是新創建)* @param walletName 錢包名稱* @param walletPassword 錢包密碼* @param addressName 地址顯示名稱* @return 地址*/String createBtcAddress(String walletName,String walletPassword,String addressName);/*** 獲取BTC余額* @param walletName 錢包名稱* @param address 地址* @return 余額*/double getBtcBalance(String walletName,String address);/*** BTC轉賬* @param walletName 錢包名稱* @param walletPassword 錢包密碼* @param toAddress 接收地址* @param quantity 轉賬數量* @return 轉賬狀態消息*/TransferModel transfetBtc(String walletName,String walletPassword,String toAddress,double quantity);/*** 獲取地址私鑰* @param walletName 錢包名稱* @param walletPassword 錢包密碼* @param address 地址* @return 私鑰*/String getBtcPrivateKey(String walletName,String walletPassword,String address);/*** 導入BTC私鑰(導入地址到錢包)* @param walletName 錢包名稱* @param walletPassword 錢包密碼* @param privateKey 私鑰* @return 是否成功*/boolean importBtcPrivateKey(String walletName,String walletPassword,String privateKey);}

4、BitcoinRPCImpl 實現類

package com.lpz.btc.api.impl;import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONArray; import com.alibaba.fastjson.JSONObject; import com.lpz.btc.api.BitcoinRPC; import com.lpz.btc.wf.bitcoin.javabitcoindrpcclient.BitcoinJSONRPCClient; import com.lpz.btc.model.exchange.TransferModel; import com.lpz.setting.DefaultBtc; import org.apache.log4j.Logger;import java.math.BigDecimal; import java.net.MalformedURLException; import java.net.URL; import java.util.ArrayList; import java.util.List;public class BitcoinRPCImpl implements BitcoinRPC {private Logger logger=Logger.getLogger(BitcoinRPCImpl.class);private DefaultBtc defaultBtc=new DefaultBtc();private String user=defaultBtc.BTCRPCUSER;//lpzprivate String password=defaultBtc.BTCRPPASSWORD;//lpzprivate String port=defaultBtc.BTCRPCPORT;//18332 因為測試網是18332 主網是8332private String host=defaultBtc.BTCRPCALLOWIP;//127.0.0.1private final int WALLET_PASS_PHRASE_TIME_OUT=60;@Overridepublic String createBtcAddress(String walletName, String walletPassword, String addressName) {try{//獲取BTC客戶端默認錢包BitcoinJSONRPCClient bitcoinClient=getBitcoinClient("");//創建錢包String walletResult=bitcoinClient.query("createwallet",walletName).toString();logger.info("錢包("+walletName+")創建成功返回==>"+walletResult+"");//獲取當前BTC客戶端錢包bitcoinClient=getBitcoinClient(walletName);//設置錢包密碼 bitcoinClient.encryptWallet(walletPassword);//創建地址return bitcoinClient.getNewAddress(addressName);}catch (Exception e){logger.error("創建錢包地址異常==>"+e.getMessage());}return null;}@Overridepublic double getBtcBalance(String walletName, String address) {try {List<JSONArray> jsonArrayList=getListAddressInfo(walletName);for(JSONArray jsonArray:jsonArrayList){if(jsonArray.getString(0).equals(address)){return jsonArray.getDoubleValue(1);}}}catch (Exception e){logger.error("錢包("+walletName+")地址("+address+")獲取余額異常==>"+e.getMessage());}return 0;}@Overridepublic TransferModel transfetBtc(String walletName, String walletPassword, String toAddress, double quantity) {TransferModel transferModel=new TransferModel();transferModel.status=transferModel.status_101;try {BitcoinJSONRPCClient bitcoinClient=getBitcoinClient(walletName);//獲取錢包余額double balance = bitcoinClient.getBalance().doubleValue();if(balance<quantity){transferModel.message="余額不足";transferModel.status=transferModel.status_103;}else{//輸入錢包密碼 bitcoinClient.walletPassPhrase(walletPassword,WALLET_PASS_PHRASE_TIME_OUT);//開始轉賬String result=bitcoinClient.sendToAddress(toAddress, BigDecimal.valueOf(quantity));logger.info("錢包("+walletName+")成功轉賬"+quantity+"個btc到"+toAddress+"交易hash==>"+result);transferModel.message="轉賬成功";transferModel.status=transferModel.status_100;}}catch (Exception e){transferModel.message="BTC轉賬異常";logger.error("錢包("+walletName+")轉賬"+quantity+"個btc到"+toAddress+"異常==>"+e.getMessage());}return transferModel;}@Overridepublic String getBtcPrivateKey(String walletName, String walletPassword, String address) {try {BitcoinJSONRPCClient bitcoinClient=getBitcoinClient(walletName);bitcoinClient.walletPassPhrase(walletPassword,WALLET_PASS_PHRASE_TIME_OUT);Object addressPrivate=bitcoinClient.query("dumpprivkey",address);return addressPrivate.toString();}catch (Exception e){logger.error("獲取地址("+address+")私鑰異常==>"+e.getMessage());}return null;}@Overridepublic boolean importBtcPrivateKey(String walletName, String walletPassword, String privateKey) {try {BitcoinJSONRPCClient bitcoinClient=getBitcoinClient(walletName);bitcoinClient.walletPassPhrase(walletPassword,WALLET_PASS_PHRASE_TIME_OUT);bitcoinClient.importPrivKey(privateKey);return true;}catch (Exception e){logger.error("導入地址私鑰("+privateKey.substring(10)+"******)到錢包("+walletName+")異常==>"+e.getMessage());}return false;}/*** 獲取BTC客戶端* @param walletName 錢包名稱* @return BTC客戶端*/private BitcoinJSONRPCClient getBitcoinClient(String walletName){BitcoinJSONRPCClient bitcoinClient=null;try {URL url = new URL("http://" + user + ':' + password + "@" + host + ":" + port + "/wallet/"+walletName+"");bitcoinClient = new BitcoinJSONRPCClient(url);} catch (MalformedURLException e) {logger.error("獲取BTC RPC錯誤==>"+e.getMessage());}return bitcoinClient;}/*** 獲取所有錢包地址信息* @param walletName 錢包名稱* @return 所有地址信息*/private List<JSONArray> getListAddressInfo(String walletName){BitcoinJSONRPCClient bitcoinClient=getBitcoinClient(walletName);List<JSONArray> resultList=new ArrayList<JSONArray>();try {Object walletAddressAll=bitcoinClient.query("listaddressgroupings");JSONArray jsonArrayAll= JSON.parseArray(JSON.toJSONString(walletAddressAll));for(int i=0;i<jsonArrayAll.size();i++){JSONArray walletArray=JSON.parseArray(jsonArrayAll.get(i).toString());for(int j=0;j<walletArray.size();j++){JSONArray jsonArray= JSON.parseArray(walletArray.getString(j));resultList.add(jsonArray);}}}catch (Exception e){logger.error("錢包("+walletName+")獲取所有地址信息異常==>"+e.getMessage());}return resultList;} }

5、測試調用 BitcoinRPCTest

package com.lpz;

import com.lpz.btc.api.BitcoinRPC;
import com.lpz.btc.api.impl.BitcoinRPCImpl;
import org.apache.log4j.Logger;
import org.junit.Test;

public class BitcoinRPCTest {
private Logger logger=Logger.getLogger(BitcoinRPCTest.class);
BitcoinRPC bitcoinRPC=new BitcoinRPCImpl();

@Test
public void getBalance(){
String walletName="lpz";
String address="2N1UMYA6poo3JFFnV3kGC5T5yrw81nRBQP4";
double balance=bitcoinRPC.getBtcBalance(walletName,address);
logger.info("錢包("+walletName+")的余額是==>"+balance);
}
@Test
public void createBtcAddress(){
String walletName="lpz_tld";
String walletPassword="lpz_tld";
String addressName="lpz_tld";
String newAddress=bitcoinRPC.createBtcAddress(walletName,walletPassword,addressName);
logger.info("錢包("+walletName+")地址==>"+newAddress);
}
} ?

效果如下：

還有一點就是我代碼里面沒有使用BitcoinJSONRPCClient 這個jar 用的是源碼

copy代碼使用的時候，引包哪里改成使用jar就好了，

然后就是jar里面包含了老版本的方法，有些方法在bitcoin core控制臺不能使用的話，在java里面也會拋異常 "找不到此方法"的

eq：上一篇里面move(轉賬)方法 java里面使用此方法就會拋異常

###最后一點是我自己測試使用的

package com.lpz.exchange.biz;import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONObject; import org.apache.log4j.Logger; import wf.bitcoin.javabitcoindrpcclient.BitcoinJSONRPCClient; import wf.bitcoin.javabitcoindrpcclient.BitcoindRpcClient;import java.math.BigDecimal; import java.net.MalformedURLException; import java.net.URL; import java.util.List;public class TestBitcoinCore {private static Logger logger= Logger.getLogger(TestBitcoinCore.class);private static void javaBitcoin(){String user = "lpz";String password = "lpz";String host = "127.0.0.1"; // String host = "192.168.86.1";String port = "18332";try {URL url = new URL("http://" + user + ':' + password + "@" + host + ":" + port + "/wallet/");BitcoinJSONRPCClient bitcoinClient = new BitcoinJSONRPCClient(url); // //創建錢包 // String walletName="longpizi5"; // String returnWallet=bitcoinClient.query("createwallet",walletName).toString(); // System.out.println(returnWallet);//設置錢包密碼 // bitcoinClient.encryptWallet("TLD6_1zns");//修改錢包密碼 walletpassphrasechange // bitcoinClient.query("TLD6_1zns","原密碼","新密碼");//未測試//獲取錢包信息System.out.println("錢包信息："+JSON.toJSONString(bitcoinClient.getWalletInfo()));//導入錢包 // bitcoinClient.dumpWallet("C:\\Users\\THIS_ODK\\Desktop\\lpz.dat"); // System.out.println(JSON.toJSONString()); // System.out.println(bitcoinClient.backupWallet(););//創建賬號 // String addressName="longlin1"; // String account=bitcoinClient.getNewAddress(addressName); // System.out.println("賬號地址："+account);BigDecimal balance = bitcoinClient.getBalance();System.out.println(balance);//獲取賬號信息 listaddressgroupingsList<BitcoindRpcClient.ReceivedAddress> receivedAddressList=bitcoinClient.listReceivedByAddress();System.out.println("錢包地址信息1："+JSON.toJSONString(receivedAddressList));Object o_listAddress=bitcoinClient.query("listaddressgroupings");System.out.println("錢包地址信息2："+ JSON.toJSONString(o_listAddress));//獲取地址私鑰 dumpprivkey//輸入錢包密碼 // bitcoinClient.walletPassPhrase("TLD6_1zns",60); // Object o_getAddressPrivate=bitcoinClient.query("dumpprivkey","2N1y1DGtXUbajM5SWyo9yRgiWAqQcPUyVEA"); // System.out.println("獲取地址私鑰："+ JSON.toJSONString(o_getAddressPrivate));/*//轉賬 sendtoaddress 錯誤: Please enter the wallet passphrase with walletpassphrase first."//輸入錢包密碼bitcoinClient.walletPassPhrase("TLD6_1zns",5000);//開始轉賬String result=bitcoinClient.sendToAddress("2N1y1DGtXUbajM5SWyo9yRgiWAqQcPUyVEA", BigDecimal.valueOf(0.01));System.out.println("交易ID："+result);*///鎖定錢包：walletlock 錢包解鎖：walletpassphrase//*} catch (MalformedURLException e) {e.printStackTrace();}}public static void main(String[] args){javaBitcoin();} }
