Spring Boot 接入支付宝全攻略

支付宝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idalipay.serverUrl=https://openapi.alipay.com/gateway.doalipay.privateKey=你的应用私钥alipay.format=jsonalipay.charset=UTF-8alipay.signType=RSA2alipay.appCertPath=/cert/appCertPublicKey_2021001164652941.crtalipay.alipayCertPath=/cert/alipayCertPublicKey_RSA2.crtalipay.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

importlombok.Data;importorg.springframework.boot.context.properties.ConfigurationProperties;importorg.springframework.context.annotation.PropertySource;importorg.springframework.stereotype.Component;@Component@PropertySource("classpath:/production/alipay.properties")@ConfigurationProperties(prefix="alipay")@DatapublicclassAliPayBean{privateStringappId;privateStringprivateKey;privateStringpublicKey;privateStringserverUrl;privateStringdomain;privateStringformat;privateStringcharset;privateStringsignType;privateStringappCertPath;privateStringalipayCertPath;privateStringalipayRootCertPath;}

5.写配置类

importcom.alipay.api.AlipayClient;importcom.alipay.api.CertAlipayRequest;importcom.alipay.api.DefaultAlipayClient;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.beans.factory.annotation.Value;importorg.springframework.context.annotation.Bean;importorg.springframework.context.annotation.Configuration;importorg.springframework.util.FileCopyUtils;importjava.io.InputStream;@ConfigurationpublicclassAliConfig{@Value("${custom.http.proxyHost}")privateStringproxyHost;@Value("${custom.http.proxyPort}")privateintproxyPort;@Value("${spring.profiles.active}")privateStringactiveEnv;@AutowiredprivateAliPayBeanaliPayBean;@Bean(name={"alipayClient"})publicAlipayClientalipayClientService()throwsException{CertAlipayRequestcertAlipayRequest=newCertAlipayRequest();//设置网关地址certAlipayRequest.setServerUrl(aliPayBean.getServerUrl());//设置应用IdcertAlipayRequest.setAppId(aliPayBean.getAppId());//设置应用私钥certAlipayRequest.setPrivateKey(aliPayBean.getPrivateKey());//设置请求格式，固定值jsoncertAlipayRequest.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{//localStringserverPath=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());}returnnewDefaultAlipayClient(certAlipayRequest);}publicStringgetCertContentByPath(Stringname){InputStreaminputStream=null;Stringcontent=null;try{inputStream=this.getClass().getClassLoader().getResourceAsStream(name);content=newString(FileCopyUtils.copyToByteArray(inputStream));}catch(Exceptione){e.printStackTrace();}returncontent;}}

6.写支付工具类

importcom.alipay.api.AlipayApiException;importcom.alipay.api.AlipayClient;importcom.alipay.api.domain.AlipayTradeAppPayModel;importcom.alipay.api.domain.AlipayTradeQueryModel;importcom.alipay.api.request.AlipayTradeAppPayRequest;importcom.alipay.api.request.AlipayTradeQueryRequest;importcom.alipay.api.response.AlipayTradeAppPayResponse;importcom.alipay.api.response.AlipayTradeQueryResponse;importlombok.extern.slf4j.Slf4j;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.beans.factory.annotation.Qualifier;importorg.springframework.stereotype.Service;/***@description:支付宝工具类*@Date:2020-08-26*/@Slf4j@ServicepublicclassAliPayUtils{@Autowired@Qualifier("alipayClient")privateAlipayClientalipayClient;/***交易查询接口*@paramrequest*@return*@throwsException*/publicbooleanisTradeQuery(AlipayTradeQueryModelmodel)throwsAlipayApiException{AlipayTradeQueryRequestrequest=newAlipayTradeQueryRequest();request.setBizModel(model);AlipayTradeQueryResponsealipayTradeQueryResponse=alipayClient.certificateExecute(request);if(alipayTradeQueryResponse.isSuccess()){returntrue;}else{returnfalse;}}/***app支付*@parammodel*@paramnotifyUrl*@return*@throwsAlipayApiException*/publicStringstartAppPay(AlipayTradeAppPayModelmodel,StringnotifyUrl)throwsAlipayApiException{AlipayTradeAppPayRequestaliPayRequest=newAlipayTradeAppPayRequest();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sdkExecuteAlipayTradeAppPayResponsealiResponse=alipayClient.sdkExecute(aliPayRequest);returnaliResponse.getBody();}/***转账接口**@paramtransferParams*@returnAlipayFundTransToaccountTransferResponse*/publicAlipayFundTransUniTransferResponsedoTransferNew(TransferParamstransferParams)throwsException{Stringtitle=(StringUtils.isNotBlank(transferParams.getRemark())?transferParams.getRemark():"转账");//转账请求入参AlipayFundTransUniTransferRequestrequest=newAlipayFundTransUniTransferRequest();//转账参数BizContentForUniTransferbizContent=newBizContentForUniTransfer();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);Participantparticipant=newParticipant();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AlipayFundTransUniTransferResponseresponse=null;try{response=alipayClient.certificateExecute(request);}catch(Exceptione){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));returnresponse;}}

Tips：转账用到的类

@DatapublicclassTransferParams{/***应用编号*/privateLongappId;/***创建人id*/privateLongcreatedBy;/***转账业务订单号*/privateStringoutBizNo;/***收款方识别方式*/privateStringpayeeType;/***收款方账号，可以是支付宝userId或者支付宝loginId*/privateStringpayeeAccount;/***转账金额，单位分*/privateStringamount;/***付款方名称*/privateStringpayerShowName;/***收款方名称*/privateStringpayeeRealName;/***备注*/privateStringremark;/***支付宝转账流水号*/privateStringorderId;}importlombok.Data;importjava.math.BigDecimal;/***支付宝转账参数*/@DatapublicclassBizContentForUniTransfer{/***业务订单号*/privateStringout_biz_no;/***订单总金额，单位为元，精确到小数点后两位，*/privateBigDecimaltrans_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；*/privateStringproduct_code;/***描述特定的业务场景，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*/privateStringbiz_scene;/***转账业务的标题，用于在支付宝用户的账单里显示*/privateStringorder_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。*/privateStringoriginal_order_id;/***业务备注*/privateStringremark;/***转账业务请求的扩展参数，支持传入的扩展参数如下：* 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；*/privateStringbusiness_params;/***支付收款对象*/privateParticipantpayee_info;}@DatapublicclassParticipant{/***参与方的唯一标识*/privateStringidentity;/***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*/privateStringidentity_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。*/privateStringname;}
