SpringBoot实现支付宝沙箱支付及退款

小咪咪 2023-02-11 15:30 232阅读 0赞

一、在[支付宝开放平台][Link 1]申请开通研发服务（需要实名认证），并根据官方文档生成公钥私钥，可参考[这篇博客][Link 2]  
二、springboot中集成支付宝沙箱支付

1.  引入alipay的sdk依赖

<dependency>
         <groupId>com.alipay.sdk</groupId>
         <artifactId>alipay-sdk-java</artifactId>
         <version>3.1.0</version>
     </dependency>

1.  编写配置文件。

package com.alipay.config;
    
    public class AlipayConfig { 
    
        // AppId
        public static String app_id = "2016102100733014";
    
        // 商户私钥
        public static  String merchant_private_key = "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";
    
        // 支付宝公钥
        public static  String alipay_public_key = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA72i7PdKclEwKdsXgtDvK3EIh6yf1IlNJB2plo0/Wu5xh+MET6630CdLwACWO/OmwYBZ5bFH1Hb/sh4puUd/G39dfR+IJcL9/NjUaUcRmS+Iwpn7FLMHyDegPW/K3gZLDsdq8ZJKu6ce5iZCcNiOGLbSYksffCzwa457FpA9Y5xhDiarLY+SFDuUlcVd6KZd06yg1ZAUjieQiRZCjiVsN1RQZgQz0pqug22dsRrJyH53vVFsbrtdGkd7OMQJMR3NvPn20T70dybSGXmpd1S38od4ImRjTDIjl6AhxMClfxXtbYwMssAz+stV86XFCp/fTS+UmzQ/NkNx5+tmimhIYdwIDAQAB";
    
        // 服务器异步通知页面路径
        public static  String notify_url = "http://www.baidu.com";
    
        // 页面跳转同步通知页面路径，回调地址
        public static  String return_url = "http://www.baidu.com";
    
        // 字符编码格式
        public static  String charset = "UTF-8";
    
        // 数据格式
        public static  String format = "json";
    
        // 签名方式
        public static  String sign_type = "RSA2";
    
        // 支付宝网关
        public static String gateway = "https://openapi.alipaydev.com/gateway.do";
    }

1.  支付实现：  
    支付请求接口

@RequestMapping("pay")
        public void toPay(HttpServletResponse response, HttpServletRequest request) throws IOException, AlipayApiException { 
            orderService.pay(response,request);
        }

实现类：

@Override
        public void pay(HttpServletResponse response, HttpServletRequest request) throws AlipayApiException, IOException{ 
            // 设置编码格式
            response.setContentType("text/html;charset=utf-8");
            PrintWriter out = response.getWriter();
            // 初始化AlipayClient
            AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.gateway, AlipayConfig.app_id, AlipayConfig.merchant_private_key,
                    AlipayConfig.format, AlipayConfig.charset, AlipayConfig.alipay_public_key, AlipayConfig.sign_type);
            //设置请求参数
            AlipayTradePagePayRequest aliPayRequest = new AlipayTradePagePayRequest();
            aliPayRequest.setReturnUrl(AlipayConfig.return_url);
            aliPayRequest.setNotifyUrl(AlipayConfig.notify_url);
    
            //商户订单号，后台可以写一个工具类生成一个订单号，必填
            String order_number = new String("20200524");
            //付款金额，从前台获取，必填
            String total_amount = new String("198");
            //订单名称/标题，可自定义
            String subject = new String("支付宝沙箱测试");
            aliPayRequest.setBizContent("{\"out_trade_no\":\"" + order_number + "\","
                    + "\"total_amount\":\"" + total_amount + "\","
                    + "\"subject\":\"" + subject + "\","
                    + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
            //请求
            String result = alipayClient.pageExecute(aliPayRequest).getBody();
            //输出
            out.println(result);//以下写自己的订单代码
            logger.info("返回结果={}",result);
        }

测试：浏览器输入：localhost:8888/pay  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3VzZXJuYW1lNjY2_size_16_color_FFFFFF_t_70]  
使用沙箱app扫码支付，支付成功，5秒后跳转到回调地址（这里回调地址设置的是百度的地址）  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3VzZXJuYW1lNjY2_size_16_color_FFFFFF_t_70 1]  
4. 退款  
退款请求接口：

@RequestMapping("refund")
        public void toRefund(HttpServletResponse response, HttpSession session) throws IOException, AlipayApiException { 
            orderService.refund(response,session);
        }

实现类：

/** * 退款 * @param response * @param session * @throws IOException * @throws AlipayApiException */
        @Override
        public void refund(HttpServletResponse response, HttpSession session) throws IOException, AlipayApiException { 
            // 设置编码格式
            response.setContentType("text/html;charset=utf-8");
            PrintWriter out = response.getWriter();
            //获得初始化的AlipayClient
            AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.gateway, AlipayConfig.app_id, AlipayConfig.merchant_private_key,
                    AlipayConfig.format, AlipayConfig.charset, AlipayConfig.alipay_public_key, AlipayConfig.sign_type);
            //设置请求参数
            AlipayTradeRefundRequest alipayRequest = new AlipayTradeRefundRequest();
            //商户订单号，必填
            String out_trade_no = new String("20200524");
            //需要退款的金额，该金额不能大于订单金额，必填
            String refund_amount = new String("198");
            //标识一次退款请求，同一笔交易多次退款需要保证唯一。如需部分退款，则此参数必传；不传该参数则代表全额退款
            String out_request_no = new String(UUID.randomUUID().toString());
            // 字符转义很重要
            alipayRequest.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\","
                    + "\"refund_amount\":\""+ refund_amount +"\","
                    + "\"out_request_no\":\""+ out_request_no +"\"}");
            //请求
            String result = alipayClient.execute(alipayRequest).getBody();
            //输出
            out.println(result);//以下写自己的订单退款代码
            logger.info("返回结果={}",result);
        }

测试：  
浏览器输入：http:localhost:8888/refund  
![在这里插入图片描述][20200524145632328.png]  
返回结果中，返回的消息为success说明退款成功。

以上就是参照网上的文章实现的支付宝沙箱支付及测试的例子。目前只接触了这么一种模拟支付的方式，还有许多支付方式，如微信支付等，有待学习~
