Spring Boot 接入支付寶，實戰來了！-有解無憂

支付寶今年推出了新的轉賬介面alipay.fund.trans.uni.transfer(升級后安全性更高，功能更加強大) ，老轉賬介面alipay.fund.trans.toaccount.transfer將不再維護，新老介面的一個區別就是新介面采用的證書驗簽方式，

使用新介面要將sdk版本升級到最新版本，博主升級時最新版本是4.10.97，

接下來看集成步驟，

1.將支付寶開放平臺里下載的3個證書放在resources下面

2.寫支付寶支付的組態檔

alipay.properties

alipay.appId=你的應用id
alipay.serverUrl=https://openapi.alipay.com/gateway.do
alipay.privateKey=你的應用私鑰
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依賴

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

4.將配置資訊注入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.寫配置類

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();
        //設定網關地址
        certAlipayRequest.setServerUrl(aliPayBean.getServerUrl());
        //設定應用Id
        certAlipayRequest.setAppId(aliPayBean.getAppId());
        //設定應用私鑰
        certAlipayRequest.setPrivateKey(aliPayBean.getPrivateKey());
        //設定請求格式，固定值json
        certAlipayRequest.setFormat(aliPayBean.getFormat());
        //設定字符集
        certAlipayRequest.setCharset(aliPayBean.getCharset());
        //設定簽名型別
        certAlipayRequest.setSignType(aliPayBean.getSignType());
        //如果是生產環境或者預演環境，則使用代理模式
        if ("prod".equals(activeEnv) || "stage".equals(activeEnv) || "test".equals(activeEnv)) {
            //設定應用公鑰證書路徑
            certAlipayRequest.setCertContent(getCertContentByPath(aliPayBean.getAppCertPath()));
            //設定支付寶公鑰證書路徑
            certAlipayRequest.setAlipayPublicCertContent(getCertContentByPath(aliPayBean.getAlipayCertPath()));
            //設定支付寶根證書路徑
            certAlipayRequest.setRootCertContent(getCertContentByPath(aliPayBean.getAlipayRootCertPath()));
            certAlipayRequest.setProxyHost(proxyHost);
            certAlipayRequest.setProxyPort(proxyPort);
 
        }else {
            //local
            String serverPath = this.getClass().getResource("/").getPath();
            //設定應用公鑰證書路徑
            certAlipayRequest.setCertPath(serverPath+aliPayBean.getAppCertPath());
            //設定支付寶公鑰證書路徑
            certAlipayRequest.setAlipayPublicCertPath(serverPath+aliPayBean.getAlipayCertPath());
            //設定支付寶根證書路徑
            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.寫支付工具類

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

    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;
        }
    }
 
    /**

        AlipayTradeAppPayRequest aliPayRequest = new AlipayTradeAppPayRequest();
        model.setProductCode("QUICK_MSECURITY_PAY");
        aliPayRequest.setNotifyUrl(notifyUrl);
        aliPayRequest.setBizModel(model);
        // 這里和普通的介面呼叫不同，使用的是sdkExecute
        AlipayTradeAppPayResponse aliResponse = alipayClient.sdkExecute(aliPayRequest);
        return aliResponse.getBody();
    }
    /**
     * 轉賬介面
     *

     */
     public AlipayFundTransUniTransferResponse doTransferNew(TransferParams transferParams) throws Exception {
 
        String title = (StringUtils.isNotBlank(transferParams.getRemark()) ? transferParams
                .getRemark() : "轉賬");
        //轉賬請求入參
        AlipayFundTransUniTransferRequest request = new AlipayFundTransUniTransferRequest();
        //轉賬引數
        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());

        bizContent.setPayee_info(participant);

        request.setBizContent(JSON.toJSONString(bizContent));
 
        //轉賬請求回傳
        AlipayFundTransUniTransferResponse response = null;
        try {
            response = alipayClient.certificateExecute(request);
        } catch (Exception e) {
 
            log.info("doTransfer exception，例外資訊：{}", e.toString());
 
            log.info("doTransfer exception，支付寶回傳資訊：{}", JSONObject.toJSONString(response));
 
        }
 
        log.info("doTransfer,AlipayFundTransUniTransferResponse:{}", JSONObject.toJSONString(response));
 
        return response;
    }
}
