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** ###

![d4709a3ea8561a69dfb2408fb5207ed6.png][]

### 2、写支付宝支付的配置文件 ###

alipay.properties

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 ###

<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 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、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;
    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();
            //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 ###

                    .getPayeeRealName() : StringUtils.EMPTY));
            bizContent.setPayee_info(participant);
            bizContent.setRemark(title);
