Spring Boot 接入支付宝支付

SpringBoot接入支付宝支付！支付宝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pertiesalipay.appId=你的应用id

alipay.serverUrl=/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.crt3、引入pom依赖

com.alipay.sdk

alipay-sdk-java

4.10.97.ALL

4、将配置信息注入AliPayBeanimport

lombok.Data;

import

perties.ConfigurationProperties;

import

org.springframework.context.annotation.PropertySource;

import

org.springframework.stereotype.Component;

@Component

@PropertySource("classpath:/production/perties")

@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;

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("${xyHost}")

private

String

proxyHost;

@Value("${xyPort}")

private

int

proxyPort;

@Value("${files.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());

//设置应用Id

certAlipayRequest.setAppId(aliPayBean.getAppId());

//设置应用私钥

certAlipayRequest.setPrivateKey(aliPayBean.getPrivateKey());

//设置请求格式，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，则使用代理模式

if

("prod".equals(activeEnv)

||

"stage".equals(activeEnv)

||

"test".equals(activeEnv))

{

//设置应用公钥证书路径

certAlipayRequest.setCertContent(getCertContentByPath(aliPayBean.getAppCertPath()));

//设置支付宝公钥证书路径

certAlipayRequest.setAlipayPublicCertContent(getCertContentByPath(aliPayBean.getAlipayCertPath()));

//设置支付宝根证书路径

certAlipayRequest.setRootCertContent(getCertContentByPath(aliPayBean.getAlipayRootCertPath()));

certAlipayRequest.setProxyHost(proxyHost);

certAlipayRequest.setProxyPort(proxyPort);

}else

{

//local

String

serverPath

=

this.getClass().getResource("/").getPath();

//设置应用公钥证书路径

certAlipayRequest.setCertPath(serverPath+aliPayBean.getAppCertPath());

//设置支付宝公钥证书路径

certAlipayRequest.setAlipayPublicCertPath(serverPath+aliPayBean.getAlipayCertPath());

//设置支付宝根证书路径

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、写支付工具类import
