关于springboot:Spring-Boot-接入支付宝实战来了

支付宝推出了新的转账接口alipay.fund.trans.uni.transfer(降级后安全性更高，性能更加弱小) ，老转账接口alipay.fund.trans.toaccount.transfer将不再保护，新老接口的一个区别就是新接口采纳的证书验签形式。

应用新接口要将sdk版本升级到最新版本，博主降级时最新版本是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上面
在这里插入图片形容
2.写支付宝领取的配置文件
alipay.properties

alipay.appId=你的利用id
alipay.serverUrl=https://openapi.alipay.com/ga...
alipay.privateKey=你的利用私钥
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;@Autowiredprivate AliPayBean aliPayBean;@Bean(name = {"alipayClient"})public AlipayClient alipayClientService() throws Exception{    CertAlipayRequest certAlipayRequest = new CertAlipayRequest();    //设置网关地址    certAlipayRequest.setServerUrl(aliPayBean.getServerUrl());    //设置利用Id    certAlipayRequest.setAppId(aliPayBean.getAppId());    //设置利用私钥    certAlipayRequest.setPrivateKey(aliPayBean.getPrivateKey());    //设置申请格局，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，则应用代理模式    if ("prod".equals(activeEnv) || "stage".equals(activeEnv) || "test".equals(activeEnv)) {        //设置利用公钥证书门路        certAlipayRequest.setCertContent(getCertContentByPath(aliPayBean.getAppCertPath()));        //设置支付宝公钥证书门路        certAlipayRequest.setAlipayPublicCertContent(getCertContentByPath(aliPayBean.getAlipayCertPath()));        //设置支付宝根证书门路        certAlipayRequest.setRootCertContent(getCertContentByPath(aliPayBean.getAlipayRootCertPath()));        certAlipayRequest.setProxyHost(proxyHost);        certAlipayRequest.setProxyPort(proxyPort);    }else {        //local        String serverPath = this.getClass().getResource("/").getPath();        //设置利用公钥证书门路        certAlipayRequest.setCertPath(serverPath+aliPayBean.getAppCertPath());        //设置支付宝公钥证书门路        certAlipayRequest.setAlipayPublicCertPath(serverPath+aliPayBean.getAlipayCertPath());        //设置支付宝根证书门路        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.写领取工具类

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;/** * 交易查问接口 * @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领取 * @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);    // 这里和一般的接口调用不同，应用的是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");    //转账申请入参    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));    //转账申请返回    AlipayFundTransUniTransferResponse response = null;    try {        response = alipayClient.certificateExecute(request);    } catch (Exception e) {        log.info("doTransfer exception，异样信息：{}", 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;}

}
Tips：转账用到的类

@Data
public class TransferParams {

/** * 利用编号 */private Long appId;/** * 创建人id */private Long createdBy;/** * 转账业务订单号 */private String outBizNo;/** * 收款方辨认形式 */private String payeeType;/** * 收款方账号，能够是支付宝userId或者支付宝loginId */private String payeeAccount;/** * 转账金额，单位分 */private String amount;/** * 付款方名称 */private String payerShowName;/** * 收款方名称 */private String payeeRealName;/** * 备注 */private String remark;/** * 支付宝转账流水号 */private String orderId;

}
import lombok.Data;
import java.math.BigDecimal;

/**

• 支付宝转账参数
  */
  @Data
  public class BizContentForUniTransfer {
  /**

  * 业务订单号*/

  private String out_biz_no;

  /**

  * 订单总金额，单位为元，准确到小数点后两位，*/

  private BigDecimal trans_amount;

  /**

  * 业务产品码，* 单笔无密转账到支付宝账户固定为:TRANS_ACCOUNT_NO_PWD；* 单笔无密转账到银行卡固定为:TRANS_BANKCARD_NO_PWD;* 收发现金红包固定为:STD_RED_PACKET；*/

  private String product_code;

  /**

  * 形容特定的业务场景，可传的参数如下：* DIRECT_TRANSFER：单笔无密转账到支付宝/银行卡, B2C现金红包;* PERSONAL_COLLECTION：C2C现金红包-领红包*/

  private String biz_scene;

  /**

  * 转账业务的题目，用于在支付宝用户的账单里显示*/

  private String order_title;

  /**

  * 原支付宝业务单号。C2C现金红包-红包支付时，传红包领取时返回的支付宝单号；* B2C现金红包、单笔无密转账到支付宝/银行卡不须要该参数。*/

  private String original_order_id;

  /**

  * 业务备注*/

  private String remark;

  /**

  * 转账业务申请的扩大参数，反对传入的扩大参数如下：* 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工夫，可选（不传入则默认为T1），* 取值T0示意预期T+0到账，取值T1示意预期T+1到账，因到账时效受银行机构解决影响，支付宝无奈保障肯定是T0或者T1到账；*/

  private String business_params;

  /**

  * 领取收款对象*/

  private Participant payee_info;
  }
  @Data
  public class Participant {

  /** * 参与方的惟一标识 */private String identity;/** * 参与方的标识类型，目前反对如下类型： * 1、ALIPAY_USER_ID 支付宝的会员ID * 2、ALIPAY_LOGON_ID：支付宝登录号，反对邮箱和手机号格局 */private String identity_type;/** * 参与方实在姓名，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;
