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; } }
tips:转账用到的类
@data public class transferparams { /** * 应用编号 */ private long appid; /** * 创建人id */ private long createdby; /** * 转账业务订单号 */ private string outbizno; /** * 收款方识别方式 */ private string payeetype; /** * 收款方账号,可以是支付宝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,精确到小数点后两位, */ 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; /** * 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 */ private string biz_scene; /** * 转账业务的标题,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; /** * 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; */ 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; }
