Spring Boot access to Alipay complete process practice

Alipay launched a new transfer interface alipay.fund.trans.uni.transfer this year (higher security after upgrading, more powerful functions), the old transfer interface alipay.fund.trans.toaccount.transfer will no longer be maintained, a difference between the new and old interfaces is the new interface to use the certificate verification method. The sdk version is upgraded to the latest version using the new interface, which is 4.10.97 when the blogger upgrades.

Next, look at the integration steps

1. Place the 3 certificates downloaded from the Alipay open platform under sources

2. Write the profile of Alipay payment

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. Introduce pom dependencies

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

4. Inject configuration information into 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. Write the configuration class

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. Write a class of payment instruments

import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.domain.AlipayTradeAppPayModel;
import com.alipay.api.domain.AlipayTradeQueryModel;

        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();
    }
    /**
     * 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;
    }
}
