springboot整合支付宝沙箱：

整合：

导入依赖：

<!--        导入支付宝的SDK 开发工具包-->
        <dependency>
            <groupId>com.alipay.sdk</groupId>
            <artifactId>alipay-sdk-java</artifactId>
            <version>4.9.79.ALL</version>
        </dependency>

之后导入两个vo类：

PayVo

package com.atguigu.gulimall.order.vo;

import lombok.Data;

@Data
public class PayVo {
    
    
    private String out_trade_no; // 商户订单号 必填
    private String subject; // 订单名称 必填
    private String total_amount;  // 付款金额 必填
    private String body; // 商品描述 可空
}

PayAsyncVo

package com.atguigu.gulimall.order.vo;

import lombok.Data;
import lombok.ToString;

@ToString
@Data
public class PayAsyncVo {
    
    

    private String gmt_create;
    private String charset;
    private String gmt_payment;
    private String notify_time;
    private String subject;
    private String sign;
    private String buyer_id;//支付者的id
    private String body;//订单的信息
    private String invoice_amount;//支付金额
    private String version;
    private String notify_id;//通知id
    private String fund_bill_list;
    private String notify_type;//通知类型； trade_status_sync
    private String out_trade_no;//订单号
    private String total_amount;//支付的总额
    private String trade_status;//交易状态  TRADE_SUCCESS
    private String trade_no;//流水号
    private String auth_app_id;//
    private String receipt_amount;//商家收到的款
    private String point_amount;//
    private String app_id;//应用id
    private String buyer_pay_amount;//最终支付的金额
    private String sign_type;//签名类型
    private String seller_id;//商家的id

}

之后在order服务中的config包下导入模版类：

package com.atguigu.gulimall.order.config;

import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.DefaultAlipayClient;

        System.out.println("支付宝的响应："+result);

        return result;

    }
}

其中要修改app_id、公钥、私钥都可以在支付宝开放平台找到

还有需要设置其中的一些信息我们是直接查询订单的详细信息进行返回：

controller：在order服务中当有人请求这个页面的时候也就是点击支付宝支付的时候就会请求这个接口之后接口获取数据返回出去一个form表单页面提交支付给支付宝支付宝就会显示一个页面

package com.atguigu.gulimall.order.web;

import com.alipay.api.AlipayApiException;
import com.atguigu.gulimall.order.config.AlipayTemplate;
import com.atguigu.gulimall.order.service.OrderService;
import com.atguigu.gulimall.order.vo.PayVo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class PayWebController {
      
      


    @Autowired
    AlipayTemplate alipayTemplate;

    @Autowired
    OrderService orderService;

    /**
     * 获取当期订单的支付信息
     * @param orderSn
     * @return
     * @throws AlipayApiException
     */
    @ResponseBody
    @GetMapping(value = "/payOrder",produces = "text/html")  //表示我们会产生一个HTMl页面的内容
    public String payOrder(@RequestParam("orderSn") String orderSn) throws AlipayApiException {
      
      

        PayVo payVo = orderService.getOrderPay(orderSn);

        //返回的是一个页面 ，我们直接将次页面交给浏览器
        String pay = alipayTemplate.pay(payVo);
        System.out.println(pay);
        //直接返回
        return pay;
    }
}

接口：

//    获取当期订单的支付信息
    PayVo getOrderPay(String orderSn);

实现类：

    /**
     * 获取当期订单的支付信息
     * @param orderSn
     * @return
     */
    @Override
    public PayVo getOrderPay(String orderSn) {
      
      
        PayVo payVo = new PayVo();
        OrderEntity order = this.getOrderByOrderSn(orderSn);
        // 表示 精确到两位数 向上取值
        BigDecimal bigDecimal = order.getPayAmount().setScale(2, BigDecimal.ROUND_UP);
        payVo.setTotal_amount(bigDecimal.toString());
        payVo.setOut_trade_no(order.getOrderSn());

        List<OrderItemEntity> order_sn = orderItemService.list(new LambdaQueryWrapper<OrderItemEntity>()
                .eq(OrderItemEntity::getOrderSn, orderSn));
        OrderItemEntity orderItemEntity = order_sn.get(0);
        payVo.setSubject(orderItemEntity.getSkuName());
        payVo.setBody(orderItemEntity.getSkuAttrsVals());

        return payVo;
    }

支付宝开放平台

直接去到支付宝开放平台

登录
去到控制台
点击最下面的沙箱操作：
选择 $(C:\Users\ACER\AppData\Roaming\Typora\typora-user-images\image-20230412105036725.png)]$

    public  String pay(PayVo vo) throws AlipayApiException {
    
    

        //AlipayClient alipayClient = new DefaultAlipayClient(AlipayTemplate.gatewayUrl, AlipayTemplate.app_id, AlipayTemplate.merchant_private_key, "json", AlipayTemplate.charset, AlipayTemplate.alipay_public_key, AlipayTemplate.sign_type);

        alipayRequest.setReturnUrl(return_url);

        System.out.println("支付宝的响应："+result);

        return result;

    }
}

之后请求member服务中的接口 return html页面:

到时候还要设置session 和拦截那些都是引依赖和复制代码和yml那些自己操作了。

订单页面的渲染：

controller：

在member服务中的MemberWebController 中创建接口：

package com.atguigu.gulimall.member.web;

import com.alibaba.fastjson.JSON;
import com.atguigu.common.utils.R;
import com.atguigu.gulimall.member.feign.OrderFeignService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;

import java.util.HashMap;
import java.util.Map;

@Controller
public class MemberWebController {
    
    

    @Autowired
    OrderFeignService orderFeignService;

    /**
     * 支付成功之后就跳转到此页面
     * @return
     */
    @GetMapping("/memberOrder.html")
    public String memberOrderPage(@RequestParam(value = "pageNum",defaultValue = "1")  Integer pageNum,
                                  Model model){
    
      //只用传递想要去第几页就行了
        //查询出当前登录用户的所有订单列表数据
        HashMap<String, Object> page = new HashMap<>();
        page.put("page",pageNum);

        R r = orderFeignService.listWithItem(page);
        System.out.println(JSON.toJSONString(r));
        model.addAttribute("orders",r);
        return "orderList";
    }
}

orderList 就是我们返回的页面使用的themleaf
