Spring Boot 接入支付寶，實(shí)戰(zhàn)來了！
作者 | 李秀才
支付寶推出了新的轉(zhuǎn)賬接口alipay.fund.trans.uni.transfer(升級(jí)后安全性更高，功能更加強(qiáng)大) ，老轉(zhuǎn)賬接口alipay.fund.trans.toaccount.transfer將不再維護(hù)，新老接口的一個(gè)區(qū)別就是新接口采用的證書驗(yàn)簽方式。
使用新接口要將sdk版本升級(jí)到最新版本，博主升級(jí)時(shí)最新版本是4.10.97。
接下來看集成步驟。
1.將支付寶開放平臺(tái)里下載的3個(gè)證書放在resources下面
2.寫支付寶支付的配置文件
alipay.properties
alipay.appId=你的應(yīng)用id
alipay.serverUrl=https://openapi.alipay.com/gateway.do
alipay.privateKey=你的應(yīng)用私鑰
alipay.format=json
alipay.charset=UTF-8
alipay.signType=RSA2
alipay.appCertPath=/cert/appCertPublicKey_2021001164652941.crt
alipay.alipayCertPath=/cert/alipayCertPublicKey_RSA2.crt
alipay.alipayRootCertPath=/cert/alipayRootCert.crt
3.引入pom依賴
<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>4.10.97.ALL</version>
</dependency>
4.將配置信息注入AliPayBean
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
@Component
@PropertySource("classpath:/production/alipay.properties")
@ConfigurationProperties(prefix = "alipay")
@Data
public class AliPayBean {
private String appId;
private String privateKey;
private String publicKey;
private String serverUrl;
private String domain;
private String format;
private String charset;
private String signType;
private String appCertPath;
private String alipayCertPath;
private String alipayRootCertPath;
}
5.寫配置類
import com.alipay.api.AlipayClient;
import com.alipay.api.CertAlipayRequest;
import com.alipay.api.DefaultAlipayClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.util.FileCopyUtils;
import java.io.InputStream;
@Configuration
public class AliConfig {
@Value("${custom.http.proxyHost}")
private String proxyHost;
@Value("${custom.http.proxyPort}")
private int proxyPort;
@Value("${spring.profiles.active}")
private String activeEnv;
@Autowired
private AliPayBean aliPayBean;
@Bean(name = {"alipayClient"})
public AlipayClient alipayClientService() throws Exception{
CertAlipayRequest certAlipayRequest = new CertAlipayRequest();
//設(shè)置網(wǎng)關(guān)地址
certAlipayRequest.setServerUrl(aliPayBean.getServerUrl());
//設(shè)置應(yīng)用Id
certAlipayRequest.setAppId(aliPayBean.getAppId());
//設(shè)置應(yīng)用私鑰
certAlipayRequest.setPrivateKey(aliPayBean.getPrivateKey());
//設(shè)置請(qǐng)求格式，固定值json
certAlipayRequest.setFormat(aliPayBean.getFormat());
//設(shè)置字符集
certAlipayRequest.setCharset(aliPayBean.getCharset());
//設(shè)置簽名類型
certAlipayRequest.setSignType(aliPayBean.getSignType());
//如果是生產(chǎn)環(huán)境或者預(yù)演環(huán)境，則使用代理模式
if ("prod".equals(activeEnv) || "stage".equals(activeEnv) || "test".equals(activeEnv)) {
//設(shè)置應(yīng)用公鑰證書路徑
certAlipayRequest.setCertContent(getCertContentByPath(aliPayBean.getAppCertPath()));
//設(shè)置支付寶公鑰證書路徑
certAlipayRequest.setAlipayPublicCertContent(getCertContentByPath(aliPayBean.getAlipayCertPath()));
//設(shè)置支付寶根證書路徑
certAlipayRequest.setRootCertContent(getCertContentByPath(aliPayBean.getAlipayRootCertPath()));
certAlipayRequest.setProxyHost(proxyHost);
certAlipayRequest.setProxyPort(proxyPort);
}else {
//local
String serverPath = this.getClass().getResource("/").getPath();
//設(shè)置應(yīng)用公鑰證書路徑
certAlipayRequest.setCertPath(serverPath+aliPayBean.getAppCertPath());
//設(shè)置支付寶公鑰證書路徑
certAlipayRequest.setAlipayPublicCertPath(serverPath+aliPayBean.getAlipayCertPath());
//設(shè)置支付寶根證書路徑
certAlipayRequest.setRootCertPath(serverPath+aliPayBean.getAlipayRootCertPath());
}
return new DefaultAlipayClient(certAlipayRequest);
}
public String getCertContentByPath(String name){
InputStream inputStream = null;
String content = null;
try{
inputStream = this.getClass().getClassLoader().getResourceAsStream(name);
content = new String(FileCopyUtils.copyToByteArray(inputStream));
}catch (Exception e){
e.printStackTrace();
}
return content;
}
}
6.寫支付工具類
import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.domain.AlipayTradeAppPayModel;
import com.alipay.api.domain.AlipayTradeQueryModel;
import com.alipay.api.request.AlipayTradeAppPayRequest;
import com.alipay.api.request.AlipayTradeQueryRequest;
import com.alipay.api.response.AlipayTradeAppPayResponse;
import com.alipay.api.response.AlipayTradeQueryResponse;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
/**

public boolean isTradeQuery(AlipayTradeQueryModel model) throws AlipayApiException {
AlipayTradeQueryRequest request = new AlipayTradeQueryRequest();
request.setBizModel(model);
AlipayTradeQueryResponse alipayTradeQueryResponse = alipayClient.certificateExecute(request);
if(alipayTradeQueryResponse.isSuccess()){
return true;
} else {
return false;
}
}
/**
* app支付

* @param notifyUrl
* @return

*/
public String startAppPay(AlipayTradeAppPayModel model, String notifyUrl) throws AlipayApiException {
AlipayTradeAppPayRequest aliPayRequest = new AlipayTradeAppPayRequest();
model.setProductCode("QUICK_MSECURITY_PAY");
aliPayRequest.setNotifyUrl(notifyUrl);
aliPayRequest.setBizModel(model);
// 這里和普通的接口調(diào)用不同，使用的是sdkExecute
AlipayTradeAppPayResponse aliResponse = alipayClient.sdkExecute(aliPayRequest);
return aliResponse.getBody();
}
/**
* 轉(zhuǎn)賬接口
*
* @param transferParams
* @return AlipayFundTransToaccountTransferResponse
*/
public AlipayFundTransUniTransferResponse doTransferNew(TransferParams transferParams) throws Exception {
String title = (StringUtils.isNotBlank(transferParams.getRemark()) ? transferParams
.getRemark() : "轉(zhuǎn)賬");
//轉(zhuǎn)賬請(qǐng)求入?yún)?br> AlipayFundTransUniTransferRequest request = new AlipayFundTransUniTransferRequest();
//轉(zhuǎn)賬參數(shù)
BizContentForUniTransfer bizContent = new BizContentForUniTransfer();
bizContent.setOut_biz_no(transferParams.getOutBizNo());
bizContent.setTrans_amount(MathUtil.changeF2Y(Math.abs(Integer.parseInt(transferParams.getAmount()))));
bizContent.setProduct_code("TRANS_ACCOUNT_NO_PWD");
bizContent.setBiz_scene("DIRECT_TRANSFER");
bizContent.setOrder_title(title);
Participant participant = new Participant();
participant.setIdentity(transferParams.getPayeeAccount());
participant.setIdentity_type(transferParams.getPayeeType());
participant.setName((StringUtils.isNotBlank(transferParams.getPayeeRealName()) ? transferParams
.getPayeeRealName() : StringUtils.EMPTY));
bizContent.setPayee_info(participant);
bizContent.setRemark(title);
request.setBizContent(JSON.toJSONString(bizContent));
//轉(zhuǎn)賬請(qǐng)求返回
AlipayFundTransUniTransferResponse response = null;
try {
response = alipayClient.certificateExecute(request);
} catch (Exception e) {
log.info("doTransfer exception，異常信息：{}", e.toString());
log.info("doTransfer exception，支付寶返回信息：{}", JSONObject.toJSONString(response));
}
log.info("doTransfer,AlipayFundTransUniTransferResponse:{}", JSONObject.toJSONString(response));
return response;
}

往 期 推 薦 1、Intellij IDEA這樣 配置注釋模板，讓你瞬間高出一個(gè)逼格！ 2、吊炸天的 Docker 圖形化工具 Portainer，必須推薦給你！ 3、最牛逼的 Java 日志框架，性能無敵，橫掃所有對(duì)手！ 4、把Redis當(dāng)作隊(duì)列來用，真的合適嗎？ 5、驚呆了，Spring Boot居然這么耗內(nèi)存！你知道嗎？ 6、全網(wǎng)最全 Java 日志框架適配方案！還有誰(shuí)不會(huì)？ 7、Spring中毒太深，離開Spring我居然連最基本的接口都不會(huì)寫了
