Java SpringBoot
支付宝去年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

Spring Boot 接入支付宝支付的 SDK 方法 - 图1

2、写支付宝支付的配置文件

alipay.properties：

  1. alipay.appId=你的应用id
  2. alipay.serverUrl=https://openapi.alipay.com/gateway.do
  3. alipay.privateKey=你的应用私钥
  4. alipay.format=json
  5. alipay.charset=UTF-8
  6. alipay.signType=RSA2
  7. alipay.appCertPath=/cert/appCertPublicKey_2021001164652941.crt
  8. alipay.alipayCertPath=/cert/alipayCertPublicKey_RSA2.crt
  9. alipay.alipayRootCertPath=/cert/alipayRootCert.crt

3、引入pom依赖

  1. <dependency>
  2.   <groupId>com.alipay.sdk</groupId>
  3.   <artifactId>alipay-sdk-java</artifactId>
  4.   <version>4.10.97.ALL</version>
  5. </dependency>

4、将配置信息注入AliPayBean

  1. import lombok.Data;
  2. import org.springframework.boot.context.properties.ConfigurationProperties;
  3. import org.springframework.context.annotation.PropertySource;
  4. import org.springframework.stereotype.Component;
  6. @Component
  7. @PropertySource("classpath:/production/alipay.properties")
  8. @ConfigurationProperties(prefix = "alipay")
  9. @Data
  10. public class AliPayBean {
  11.     private String appId;
  12.     private String privateKey;
  13.     private String publicKey;
  14.     private String serverUrl;
  15.     private String domain;
  16.     private String format;
  17.     private String charset;
  18.     private String signType;
  19.     private String appCertPath;
  20.     private String alipayCertPath;
  21.     private String alipayRootCertPath;
  23. }

5、写配置类

  1. import com.alipay.api.AlipayClient;
  2. import com.alipay.api.CertAlipayRequest;
  3. import com.alipay.api.DefaultAlipayClient;
  4. import org.springframework.beans.factory.annotation.Autowired;
  5. import org.springframework.beans.factory.annotation.Value;
  6. import org.springframework.context.annotation.Bean;
  7. import org.springframework.context.annotation.Configuration;
  8. import org.springframework.util.FileCopyUtils;
  10. import java.io.InputStream;
  13. @Configuration
  14. public class AliConfig {
  16.     @Value("${custom.http.proxyHost}")
  17.     private String proxyHost;
  18.     @Value("${custom.http.proxyPort}")
  19.     private int proxyPort;
  20.     @Value("${spring.profiles.active}")
  21.     private String activeEnv;
  23.     @Autowired
  24.     private AliPayBean aliPayBean;
  26.     @Bean(name = {"alipayClient"})
  27.     public AlipayClient alipayClientService() throws Exception{
  28.         CertAlipayRequest certAlipayRequest = new CertAlipayRequest();
  29.         //设置网关地址
  30.         certAlipayRequest.setServerUrl(aliPayBean.getServerUrl());
  31.         //设置应用Id
  32.         certAlipayRequest.setAppId(aliPayBean.getAppId());
  33.         //设置应用私钥
  34.         certAlipayRequest.setPrivateKey(aliPayBean.getPrivateKey());
  35.         //设置请求格式，固定值json
  36.         certAlipayRequest.setFormat(aliPayBean.getFormat());
  37.         //设置字符集
  38.         certAlipayRequest.setCharset(aliPayBean.getCharset());
  39.         //设置签名类型
  40.         certAlipayRequest.setSignType(aliPayBean.getSignType());
  41.         //如果是生产环境或者预演环境，则使用代理模式
  42.         if ("prod".equals(activeEnv) || "stage".equals(activeEnv) || "test".equals(activeEnv)) {
  43.             //设置应用公钥证书路径
  44.             certAlipayRequest.setCertContent(getCertContentByPath(aliPayBean.getAppCertPath()));
  45.             //设置支付宝公钥证书路径
  46.             certAlipayRequest.setAlipayPublicCertContent(getCertContentByPath(aliPayBean.getAlipayCertPath()));
  47.             //设置支付宝根证书路径
  48.             certAlipayRequest.setRootCertContent(getCertContentByPath(aliPayBean.getAlipayRootCertPath()));
  49.             certAlipayRequest.setProxyHost(proxyHost);
  50.             certAlipayRequest.setProxyPort(proxyPort);
  52.         }else {
  53.             //local
  54.             String serverPath = this.getClass().getResource("/").getPath();
  55.             //设置应用公钥证书路径
  56.             certAlipayRequest.setCertPath(serverPath+aliPayBean.getAppCertPath());
  57.             //设置支付宝公钥证书路径
  58.             certAlipayRequest.setAlipayPublicCertPath(serverPath+aliPayBean.getAlipayCertPath());
  59.             //设置支付宝根证书路径
  60.             certAlipayRequest.setRootCertPath(serverPath+aliPayBean.getAlipayRootCertPath());
  61.         }
  62.         return new DefaultAlipayClient(certAlipayRequest);
  63.     }
  64.     public String getCertContentByPath(String name){
  65.         InputStream inputStream = null;
  66.         String content = null;
  67.         try{
  68.             inputStream = this.getClass().getClassLoader().getResourceAsStream(name);
  69.             content = new String(FileCopyUtils.copyToByteArray(inputStream));
  70.         }catch (Exception e){
  71.             e.printStackTrace();
  72.         }
  73.         return content;
  74.     }
  76. }

6、写支付工具类

  1. import com.alipay.api.AlipayApiException;
  2. import com.alipay.api.AlipayClient;
  3. import com.alipay.api.domain.AlipayTradeAppPayModel;
  4. import com.alipay.api.domain.AlipayTradeQueryModel;
  5. import com.alipay.api.request.AlipayTradeAppPayRequest;

  8. import com.alipay.api.response.AlipayTradeQueryResponse;
  9. import lombok.extern.slf4j.Slf4j;

  35.             return true;
  36.         } else {

  38.         }
  39.     }

  52.         aliPayRequest.setBizModel(model);
  53.         // 这里和普通的接口调用不同，使用的是sdkExecute
  54.         AlipayTradeAppPayResponse aliResponse = alipayClient.sdkExecute(aliPayRequest);

  71.         bizContent.setOut_biz_no(transferParams.getOutBizNo());
  72.         bizContent.setTrans_amount(MathUtil.changeF2Y(Math.abs(Integer.parseInt(transferParams.getAmount()))));
