关于java:Spring-Boot-接入支付宝实战来了

jiezi

支付宝往年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

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/gateway.do
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;
 
    @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;
/**

@Slf4j
@Service
public class AliPayUtils {
    @Autowired
    @Qualifier("alipayClient")
    private AlipayClient alipayClient;
 
    /**

     * @return

     */
    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;
    }
}
