SpringBoot接入支付宝支付的方法步骤

支付宝今年推出了新的转账接口alipay.fund.trans.uni.transfer(升级后安全性更高，功能更加强大) ，老转账接口alipay.fund.trans.toaccount.transfer将不再维护，新老接口的一个区别就是新接口采用的证书验签方式。使用新接口要将sdk版本升级到最新版本，博主升级时最新版本是4.10.97。接下来看集成步骤

1.将支付宝开放平台里下载的3个证书放在resources下面

2.写支付宝支付的配置文件

alipay.properties

alipay.appId=你的应用id
alipay.serverUrl=https://openapi.alipay.com/gateway.do
alipay.privateKey=你的应用私钥
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依赖

<dependency>
  <groupId>com.alipay.sdk</groupId>
  <artifactId>alipay-sdk-java</artifactId>
  <version>4.10.97.ALL</version>
</dependency>

4.将配置信息注入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.写配置类

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();
  //设置网关地址
  certAlipayRequest.setServerUrl(aliPayBean.getServerUrl());
  //设置应用Id
  certAlipayRequest.setAppId(aliPayBean.getAppId());
  //设置应用私钥
  certAlipayRequest.setPrivateKey(aliPayBean.getPrivateKey());
  //设置请求格式，固定值json
  certAlipayRequest.setFormat(aliPayBean.getFormat());
  //设置字符集
  certAlipayRequest.setCharset(aliPayBean.getCharset());
  //设置签名类型
  certAlipayRequest.setSignType(aliPayBean.getSignType());
  //如果是生产环境或者预演环境，则使用代理模式
  if ("prod".equals(activeEnv) || "stage".equals(activeEnv) || "test".equals(activeEnv)) {
   //设置应用公钥证书路径
   certAlipayRequest.setCertContent(getCertContentByPath(aliPayBean.getAppCertPath()));
   //设置支付宝公钥证书路径
   certAlipayRequest.setAlipayPublicCertContent(getCertContentByPath(aliPayBean.getAlipayCertPath()));
   //设置支付宝根证书路径
   certAlipayRequest.setRootCertContent(getCertContentByPath(aliPayBean.getAlipayRootCertPath()));
   certAlipayRequest.setProxyHost(proxyHost);
   certAlipayRequest.setProxyPort(proxyPort);
 
  }else {
   //local
   String serverPath = this.getClass().getResource("/").getPath();
   //设置应用公钥证书路径
   certAlipayRequest.setCertPath(serverPath+aliPayBean.getAppCertPath());
   //设置支付宝公钥证书路径
   certAlipayRequest.setAlipayPublicCertPath(serverPath+aliPayBean.getAlipayCertPath());
   //设置支付宝根证书路径
   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.写支付工具类

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;
/**
 * @description:支付宝工具类
 * @Date:2020-08-26
 */
@Slf4j
@Service
public class AliPayUtils {
 @Autowired
 @Qualifier("alipayClient")
 private AlipayClient alipayClient;
 
 /**
  * 交易查询接口
  * @param request
  * @return
  * @throws Exception
  */
 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 model
  * @param notifyUrl
  * @return
  * @throws AlipayApiException
  */
 public String startAppPay(AlipayTradeAppPayModel model, String notifyUrl) throws AlipayApiException {
  AlipayTradeAppPayRequest aliPayRequest = new AlipayTradeAppPayRequest();
  model.setProductCode("QUICK_MSECURITY_PAY");
  aliPayRequest.setNotifyUrl(notifyUrl);
  aliPayRequest.setBizModel(model);
  // 这里和普通的接口调用不同，使用的是sdkExecute
  AlipayTradeAppPayResponse aliResponse = alipayClient.sdkExecute(aliPayRequest);
  return aliResponse.getBody();
 }
 /**
  * 转账接口
  *
  * @param transferParams
  * @return AlipayFundTransToaccountTransferResponse
  */
  public AlipayFundTransUniTransferResponse doTransferNew(TransferParams transferParams) throws Exception {
 
  String title = (StringUtils.isNotBlank(transferParams.getRemark()) ? transferParams
    .getRemark() : "转账");
  //转账请求入参
  AlipayFundTransUniTransferRequest request = new AlipayFundTransUniTransferRequest();
  //转账参数
  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));
 
  //转账请求返回
  AlipayFundTransUniTransferResponse response = null;
  try {
   response = alipayClient.certificateExecute(request);
  } catch (Exception e) {
 
   log.info("doTransfer exception，异常信息：{}", e.toString());
 
   log.info("doTransfer exception，支付宝返回信息：{}", JSONObject.toJSONString(response));
 
  }
 
  log.info("doTransfer,AlipayFundTransUniTransferResponse:{}", JSONObject.toJSONString(response));
 
  return response;
 }
}

  */
 private String order_title;
 
 /**
  * 原支付宝业务单号。C2C现金红包-红包领取时，传红包支付时返回的支付宝单号；
  * B2C现金红包、单笔无密转账到支付宝/银行卡不需要该参数。
  */
 private String original_order_id;
 
 /**
  * 业务备注
  */
 private String remark;
 
 /**

  * 1、sub_biz_scene 子业务场景，红包业务必传，取值REDPACKET，C2C现金红包、B2C现金红包均需传入；
  * 2、withdraw_timeliness为转账到银行卡的预期到账时间，可选（不传入则默认为T1），
  * 取值T0表示预期T+0到账，取值T1表示预期T+1到账，因到账时效受银行机构处理影响，支付宝无法保证一定是T0或者T1到账；
  */
 private String business_params;
 
 /**
  * 支付收款对象
  */
 private Participant payee_info;
}

@Data
public class Participant {
 /**
  * 参与方的唯一标识
  */
 private String identity;
 
 /**
  * 参与方的标识类型，目前支持如下类型：
  * 1、ALIPAY_USER_ID 支付宝的会员ID
  * 2、ALIPAY_LOGON_ID：支付宝登录号，支持邮箱和手机号格式
  */
 private String identity_type;
 
 /**
  * 参与方真实姓名，如果非空，将校验收款支付宝账号姓名一致性。
  * 当identity_type=ALIPAY_LOGON_ID时，本字段必填。
  */
 private String name;
