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(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

     com.alipay.sdk
     alipay-sdk-java
     4.10.97.ALL


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;

@Slf4j
@Service
public class AliPayUtils {
    @Autowired
    @Qualifier("alipayClient")
    private AlipayClient alipayClient;
 
    
    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;
 }
    }
 
    
    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();
    }
    
     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 {
 
    
    private Long appId;
 
    
    private Long createdBy;
 
    
    private String outBizNo;
 
    
    private String payeeType;
 
    
    private String payeeAccount;
 
    
    private String amount;
 
    
    private String payerShowName;
 
    
    private String payeeRealName;
 
    
    private String remark;
 
    
    private String orderId;
}
import lombok.Data;

import java.math.BigDecimal;


@Data
public class BizContentForUniTransfer {
   
   private String out_biz_no;

   
   private BigDecimal trans_amount;

   
   private String product_code;

   
   private String biz_scene;

   
   private String order_title;

   
   private String original_order_id;

   
   private String remark;

   
   private String business_params;

   
   private Participant payee_info;
}

@Data
public class Participant {
    
    private String identity;
 
    
    private String identity_type;
 
    
    private String name;
}
