## SpringBoot实现支付宝沙箱 ##

接入文档：https://opendocs.alipay.com/common/02khjm

### 1 申请沙箱账号并配置 ###

https://open.alipay.com/develop/manage  
①申请沙箱账号

②配置公钥  
![在这里插入图片描述][de9432569213470281ca9fed9e5aaf49.png]

> 选择启用，启用之后选择查看，可以看到有应用公钥、应用私钥、支付宝公钥，这三个是需要记住的

如果要测试APP支付的，可以下载沙箱版支付宝APP(暂支持Android)

沙箱版的支付宝APP，系统会默认给我们配置好账号，不用我们自己注册  
![在这里插入图片描述][f1349d389fe949549d86418fa0170b03.png]  
沙箱版APP下载，在页面左侧的沙箱工具中，直接使用正式版支付宝扫码下载即可

### 2 创建SpringBoot项目配置环境 ###

> 此处为了演示，我就没有创建数据库、以及实体类等操作了

如果有人想看稍微完整的过程，可以在gitee或者GitHub上搜索Alipay-demo  
例如：https://gitee.com/xqnode/alipay-demo?\_from=gitee\_search

注意：我们如果想要支付宝调用我们，需要暴露在公网，此处我使用内网穿透工具natapp实现

[natapp官网][natapp]  
大家参考网上的教程实现即可，该工具是免费的。

    alipay.notifyUrl="natapp映射的网址"/alipay/notify

pom文件所需依赖：

<dependency>
        <groupId>com.alipay.sdk</groupId>
        <artifactId>alipay-sdk-java</artifactId>
        <version>4.16.2.ALL</version>
    </dependency>

#### 2.2 配置类【封装公私钥】 ####

AlipayConfig

@Data
    @Component
    @ConfigurationProperties(prefix = "alipay")
    public class AlipayConfig {
        
        private String appId;
        //应用私钥
        private String appPrivateKey;
        //阿里公钥
        private String alipayPublicKey;
        //阿里调用我们的地址【内网穿透】
        private String notifyUrl;
    }

#### 2.3 创建实体类【与阿里交互的对象】 ####

//与阿里交互的对象
    @Data
    public class AliPay {
        
        private String traceNo;//我们的订单号
    
        private Double totalAmount;//总金额
    
        private String subject;//主题
    
        private String alipayTraceNo;//阿里的流水号
    
    }

#### 2.4 controller ####

##### ①请求支付宝 #####

@GetMapping("/pay") // ?subject=xxx&traceNo=xxx&totalAmount=xxx
    public void pay(AliPay aliPay, HttpServletResponse response) throws IOException {
        
        //1.创建client，通过阿里SDK提供的client，负责调用支付宝的API
        AlipayClient alipayClient = new DefaultAlipayClient(GATEWAY_URL,
                alipayConfig.getAppId(),
                alipayConfig.getAppPrivateKey(),
                FORMAT,
                CHARSET,
                alipayConfig.getAlipayPublicKey(),
                SIGN_TYPE);
        //2.创建request，并设置request参数
        AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
        request.setNotifyUrl(alipayConfig.getNotifyUrl());
        JSONObject bizContent = new JSONObject();
        bizContent.put("out_trade_no", aliPay.getTraceNo());//我们自己生成的订单编号
        bizContent.put("total_amount", aliPay.getTotalPrice());//订单总金额
        bizContent.put("subject", aliPay.getSubject());//支付名称
        bizContent.put("product_code", "FAST_INSTANT_TRADE_PAY");//固定配置
        request.setBizContent(bizContent.toString());
    
        //执行请求，拿到响应的结果，返回给浏览器
        String form = "";
        try{
        
            form = alipayClient.pageExecute(request).getBody();//调用SDK生成表单
        } catch (AlipayApiException e) {
        
            e.printStackTrace();
        }
        //设置响应结果，将返回的内容写出到浏览器
        response.setContentType("text/html;charset=" + CHARSET);
        response.getWriter().write(form);//直接将完整的表单html输出到页面
        response.getWriter().flush();
        response.getWriter().close();
    
    }

##### ②支付宝回调【post】 #####

/**
     * 支付宝异步回调【必须是POST】
     * @return
     */
    @PostMapping("/notify")
    public String payNotify(HttpServletRequest request) throws AlipayApiException {
        
        if(request.getParameter("trade_status").equals("TRADE_SUCCESS")){
        
            System.out.println("-------------支付宝异步回调----");
            Map<String, String> params = new HashMap<>();
            Map<String, String[]> requestParams = request.getParameterMap();
            System.out.println("-----params-----------");
            for(String name : requestParams.keySet()){
        
                params.put(name, request.getParameter(name));
                System.out.println(name +"     " + request.getParameter(name));
            }
    
            String outTradeNo = params.get("out_trade_no");
            String gmtPayment = params.get("gmt_payment");//支付时间
            String alipayTradeNo = params.get("trade_no");
    
            String sign = params.get("sign");//拿到签名
            String content = AlipaySignature.getSignCheckContentV1(params);
            boolean checkSignature = AlipaySignature.rsa256CheckContent(content,
                    sign,
                    alipayConfig.getAlipayPublicKey(),
                    "UTF-8");//验证签名
            //支付宝验签
            if(checkSignature){
        
                //验签通过
                System.out.println("交易名称: " + params.get("subject"));
                System.out.println("交易状态: " + params.get("trade_status"));
                System.out.println("支付宝交易凭证号: " + params.get("trade_no"));
                System.out.println("商户订单号: " + params.get("out_trade_no"));
                System.out.println("交易金额: " + params.get("total_amount"));
                System.out.println("买家在支付宝唯一id: " + params.get("buyer_id"));
                System.out.println("买家付款时间: " + params.get("gmt_payment"));
                System.out.println("买家付款金额: " + params.get("buyer_pay_amount"));
    
    
                // 查询订单
                //TODO 支付成功，操作数据库，创建对应订单，修改对应商品数据
    
            }
        }
    
        return "success";
    }
