引入开发包

<dependency>
        <groupId>com.github.javen205</groupId>
        <artifactId>IJPay-AliPay</artifactId>
        <version>2.4.0</version>
    </dependency>

1.  实例化支付宝支付配置

package com.jyl.shop.config.alipay;
    
    import com.ijpay.alipay.AliPayApiConfig;
    import com.ijpay.alipay.AliPayApiConfigKit;
    import lombok.Data;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import java.security.NoSuchAlgorithmException;
    import java.security.spec.InvalidKeySpecException;
    
    /** * 开发公司：个人 * 版权：个人 * <p> * PayConfig * * @author 刘志强 * @created Create Time: 2020/2/14 */
    @Data
    @Configuration
    public class PayConfig { 
    
    
        @Value("${ali.pay.appId}")
        public String appId;
    
        /** * 支付宝公钥 */
        @Value("${ali.pay.publicKey}")
        public String publicKey;
    
        /** * RSA2秘钥（私钥） */
        @Value("${ali.pay.privateKey}")
        public String privateKey;
    
        /** * 使用沙箱环境时将 serverUrl 设置为 https://openapi.alipaydev.com/gateway.do 使用正式环境时设置为 https://openapi.alipay.com/gateway.do */
        @Value("${ali.pay.serverUrl}")
        public String serverUrl;
    
    
        @Bean
        public AliPayApiConfig aliPayApiConfig() throws NoSuchAlgorithmException, InvalidKeySpecException { 
            AliPayApiConfig aliPayApiConfig = AliPayApiConfig.builder()
                    .setAppId(appId)
                    .setAliPayPublicKey(publicKey)
                    .setCharset("UTF-8")
                    .setPrivateKey(privateKey)
                    .setServiceUrl(serverUrl)
                    .setSignType("RSA2")
                    .build(); // 普通公钥方式
            AliPayApiConfigKit.setThreadLocalAliPayApiConfig(aliPayApiConfig);
            return aliPayApiConfig;
        }
    }

### 要点（如果生成的私钥是rsa的） ###

1.  生成的私钥先要去除换行
2.  然后 privateKey rsa 在转成 PKCS8 的
3.  [在线过滤文本行所有换行][Link 1]
4.  [在线RSA PKCS\#1 转 PKCS8格式私钥、convert pkcs8 to pkcs\#1 private key][RSA PKCS_1 _ PKCS8_convert pkcs8 to pkcs_1 private key]

### 支付实例 ###

public void zfbH5Pay(ShopOrders shopOrders) { 
            AlipayTradeWapPayModel alipayTradeWapPayModel = new AlipayTradeWapPayModel();
            alipayTradeWapPayModel.setSubject("电信权益商品");
            alipayTradeWapPayModel.setOutTradeNo(shopOrders.getOrderNo());
            alipayTradeWapPayModel.setTotalAmount(String.valueOf(shopOrders.getRealTotalMoney()));
            // 用户付款中途退出返回商户网站的地址
            alipayTradeWapPayModel.setQuitUrl("http://member.360tp.cn:8000/index?tab=list");
            // 销售产品码，商家和支付宝签约的产品码 固定值QUICK_WAP_WAY
            alipayTradeWapPayModel.setProductCode("QUICK_WAP_WAY");
            try { 
                AliPayApi.wapPay(httpServletResponse, alipayTradeWapPayModel, "同步回调地址", "异步回调地址");
            } catch (AlipayApiException e) { 
                e.printStackTrace();
            } catch (IOException e) { 
                e.printStackTrace();
            }
        }
