Alipay alipay has launched a new transfer interface. The fund. Trans. Uni. Transfer (upgraded security is higher, more powerful), the old transfer interface alipay. The fund. Trans. Toaccount. The transfer will no longer maintain, One difference between the old and new interfaces is the certificate verification method adopted by the new interface.
To use the new interface, upgrade the SDK version to the latest version, which is 4.10.97 when the blogger upgrades.
Next, look at the integration steps.
1. Place the three certificates downloaded from alipay open platform under Resources 
Alipay. AppId = your application id alipay.serverUrl=https://openapi.alipay.com/gateway.do alipay. The privateKey = you private key of the application of alipay. The 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.crtCopy the code3. Introduce POM dependencies
< the dependency > < groupId > com. Alipay. The SDK < / groupId > < artifactId > alipay - SDK - Java < / artifactId > < version > 4.10.97. ALL < / version > </dependency>Copy the code4. Inject the configuration information into 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 serverUrl;
private String domain;
private String format;

}
Copy the code5. Write configuration classes
