关于springboot:Spring-Boot-接入支付宝实战来了

jiezi

支付宝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
在这里插入图片形容
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/ga…
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;
/**

  • @description: 支付宝工具类
  • @Date:2020-08-26
    */

@Slf4j
@Service
public class AliPayUtils {

@Autowired
@Qualifier("alipayClient")
private AlipayClient alipayClient;

/**
 * 交易查问接口
 * @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 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;
}

}

    private String order_title;

    /**

    private String business_params;

    /**

    * 领取收款对象

    private Participant payee_info;
    }
    @Data
    public class Participant {

    /**
 * 参与方的惟一标识
 */
private String identity;

/**
 * 参与方的标识类型，目前反对如下类型：* 1、ALIPAY_USER_ID 支付宝的会员 ID
 * 2、ALIPAY_LOGON_ID：支付宝登录号，反对邮箱和手机号格局
 */
private String identity_type;

/**
