SpringBoot接入支付宝支付的方法步骤

时间：2020-12-13来源：www.pcxitongcheng.com作者：电脑系统城

支付宝今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

2.写支付宝支付的配置文件

alipay.properties

8
9 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.引入pom依赖

5 <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 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;

}

InputStream inputStream = null;
String content = null;
try{

content = new String(FileCopyUtils.copyToByteArray(inputStream));
}catch (Exception e){
e.printStackTrace();
}
return content;
}

}
