SpringBoot沙箱环境支付宝支付

1、创建应用
登录支付宝开放平台
支付宝开放平台网址：支付宝 (alipay.com)

支付宝开放平台

下拉最下边

2、获取appId、支付宝公钥、应用私钥

3、开始创建spring boot项目

#支付宝支付配置
alipay:#你的APPIDappId: 902************#你的应用私钥privateKey: MIIE***********#支付宝公钥publicKey:  MIIB***********#生产环境网关地址#serverUrl: https://openapi.alipay.com/gateway.do#沙箱环境网关地址serverUrl: https://openapi-sandbox.dl.alipaydev.com/gateway.do#生产环境域domain: gw.open.alipay.com#回调urlnoticeUrl: https://ie2204wi1077.vicp.fun

4、导入pom依赖

<dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-sdk-java</artifactId><version>4.39.134.ALL</version></dependency><!-- https://mvnrepository.com/artifact/com.alipay.sdk/alipay-easysdk --><dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-easysdk</artifactId><version>2.2.2</version></dependency><dependency><groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-core</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><scope>provided</scope></dependency>

5、创建Controller

准备好密钥

import com.alipay.api.AlipayApiException;
import com.pig4cloud.pigx.alipay.util.PayVo;
import com.pig4cloud.pigx.alipay.service.AliPayService;
import com.pig4cloud.pigx.common.core.util.R;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;@Slf4j
@RequestMapping("/alipay")
@RestController
public class AliPayController {@Resourceprivate AliPayService aliPayService;@RequestMapping("/pay")public R paymoney(@RequestBody PayVo payVo) throws AlipayApiException {return R.ok(aliPayService.pay(payVo));}@PostMapping("/notify")  // 注意这里必须是POST接口public R notify(HttpServletRequest request) throws Exception {return R.ok(aliPayService.notify(request));}}

6、创建一个实体类来接受前端传递过来的参数
这是我的


import lombok.Data;@Data
public class PayVo {//订单idprivate String orderId;//会诊idprivate String conId;//支付金额private String money;//支付标题private String title;//成功返回页面private String url;}

7、AliPayService.java

import com.alipay.api.AlipayApiException;
import com.baomidou.mybatisplus.extension.service.IService;
import com.pig4cloud.pigx.alipay.util.PayVo;
import com.pig4cloud.pigx.ybiot.entity.MzRecipe;
import com.pig4cloud.pigx.ybiot.entity.RecipeDTO;
import org.springframework.web.bind.annotation.RequestBody;import javax.servlet.http.HttpServletRequest;/*** 支付宝支付接口** @author gwh* @date 2024-11-11 09:08:14*/
public interface AliPayService extends IService<MzRecipe> {/*** 支付接口* @param payVo* @return*/RecipeDTO pay(@RequestBody PayVo payVo) throws AlipayApiException;RecipeDTO notify(HttpServletRequest request) throws Exception;}

8、AliPayServiceImpl.java


import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.AlipayConfig;
import com.alipay.api.DefaultAlipayClient;
import com.alipay.api.domain.AlipayTradeWapPayModel;

import com.pig4cloud.pigx.ybiot.entity.MzRecipe;
import com.pig4cloud.pigx.ybiot.entity.RecipeDTO;
import com.pig4cloud.pigx.ybiot.mapper.MzRecipeMapper;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
