    <groupId>com.alipay.sdk</groupId>
    <artifactId>alipay-sdk-java</artifactId>
    <version>4.9.28.ALL</version>
</dependency>

2).支付的工具类AlipayTemplate

把app_id 、merchant_private_key 、alipay_public_key 、notify_url、return_url、gatewayUrl 写成自己（公司）的

//支付宝的工具类

@ConfigurationProperties(prefix = "alipay")
@Component
@Data
public class AlipayTemplate {

    //在支付宝创建的应用的id
    private String app_id = "2021000117668106";

    // 商户私钥，您的PKCS8格式RSA2私钥

    // 服务器[异步通知]页面路径  需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问
    // 支付宝会悄悄的给我们发送一个请求，告诉我们支付成功的信息

    // 支付宝网关； https://openapi.alipaydev.com/gateway.do
     private String gatewayUrl = "https://openapi.alipaydev.com/gateway.do";

    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);
        //1、根据支付宝的配置生成一个支付客户端
        AlipayClient alipayClient = new DefaultAlipayClient(gatewayUrl,
                app_id, merchant_private_key, "json",
                charset, alipay_public_key, sign_type);

        //2、创建一个支付请求 //设置请求参数
        AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
        alipayRequest.setReturnUrl(return_url);
        alipayRequest.setNotifyUrl(notify_url);

        //商户订单号，商户网站订单系统中唯一订单号，必填
        String out_trade_no = vo.getOut_trade_no();
        //付款金额，必填
        String total_amount = vo.getTotal_amount();
        //订单名称，必填
        String subject = vo.getSubject();
        //商品描述，可空
        String body = vo.getBody();

        alipayRequest.setBizContent("{\"out_trade_no\":\"" + out_trade_no + "\","
                + "\"total_amount\":\"" + total_amount + "\","
                + "\"subject\":\"" + subject + "\","
                + "\"body\":\"" + body + "\","
                + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");

        String result = alipayClient.pageExecute(alipayRequest).getBody();

        //会收到支付宝的响应，响应的是一个页面，只要浏览器显示这个页面，就会自动来到支付宝的收银台页面
        System.out.println("支付宝的响应：" + result);

        return result;

    }
}

3).支付的数据

@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
}

@ToString
@Data
public class PayAsyncVo {
    private String gmt_create;
    private String charset;
    private String gmt_payment;
    private Date 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
}

4).修改支付页面-pay.html

	<li>
       <img src="/static/order/pay/img/zhifubao.png" style="weight:auto;height:30px;" alt="">
       <a th:href="'http://order.gulimall.com/payOrder?orderSn='+${submitOrderResp.order.orderSn}">支付宝</a>
    </li>

5.1).controller1 将支付页让浏览器显示-order

5.1.1)controller

produces = “text/html”

/**
 * 描述：支付宝 支付的控制器
 */
@Controller
public class PayWebController {
    @Autowired
    AlipayTemplate alipayTemplate;
    @Autowired
    OrderService orderService;

    @ResponseBody
    @GetMapping(value = "/payOrder",produces = "text/html")
    public String payOrder(@RequestParam("orderSn") String orderSn) throws AlipayApiException {
        PayVo payVo=  orderService.getPayOrder(orderSn);
        String pay = alipayTemplate.pay(payVo);
        //返回的是一个页面。把此页面直接交给浏览器就行。produces = "text/html"
        System.out.println("pay" + pay);
        return pay;
    }
}

5.1.2).order的实现类

 @Override
    public PayVo getPayOrder(String orderSn) {
        PayVo payVo = new PayVo();

        OrderEntity order = this.getOrderByOrderSn(orderSn);
        BigDecimal bigDecimal = order.getTotalAmount().setScale(2, BigDecimal.ROUND_UP);
        payVo.setTotal_amount(bigDecimal.toString());//付款金额
        payVo.setOut_trade_no(order.getOrderSn());//订单号

        List<OrderItemEntity> orderItem = orderItemService.list(new QueryWrapper<OrderItemEntity>().eq("order_sn", orderSn));
        OrderItemEntity itemEntity = orderItem.get(0);
        payVo.setSubject(itemEntity.getSkuName());//订单名称

        payVo.setBody(itemEntity.getSkuAttrsVals());//商品描述

        return payVo;
    }

5.1.3).测试-ok

下订单，支付，用户沙箱密码
支付宝沙箱账号 https://openhome.alipay.com/platform/appDaily.htm?tab=account

5.2).controller2支付成功后，跳到用户的订单列表页-member

5.2.1).修改 AlipayTemplate

private String return_url = "http://member.gulimall.com/memberOrder.html";

5.2.1).添加feign配置类，防止cookie丢失

/**
 * @Description: feign拦截器功能 
 **/

@Configuration
public class GuliFeignConfig {

    @Bean("requestInterceptor")
    public RequestInterceptor requestInterceptor() {

        RequestInterceptor requestInterceptor = new RequestInterceptor() {
            @Override
            public void apply(RequestTemplate template) {
                //1、使用RequestContextHolder拿到刚进来的请求数据
                ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();

                if (requestAttributes != null) {
                    //老请求
                    HttpServletRequest request = requestAttributes.getRequest();

                    if (request != null) {
                        //2、同步请求头的数据（主要是cookie）
                        //把老请求的cookie值放到新请求上来，进行一个同步
                        String cookie = request.getHeader("Cookie");
                        template.header("Cookie", cookie);
                    }
                }
            }
        };
        return requestInterceptor;
    }

}

5.2.2).导入资源

a.导入订单列表页到member项目

把index.html修改为orderList.html
在这里插入图片描述

b.member导入thymeleaf依赖

   <!--thymeleaf-->
   <dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-thymeleaf</artifactId>
  </dependency>

c.member 关闭thymeleaf缓存

#thymeleaf 关闭缓存
spring.thymeleaf.cache=false

d.nginx上传静态资源

在这里插入图片描述

e.修改orderList.html静态资源的路径

在这里插入图片描述

f.修改域名

在这里插入图片描述

g.修改网关

        - id: gulimall_member_route
          uri: lb://gulimall-member
          predicates:
            - Host=member.gulimall.com

5.2.3).添加拦截器

a.拦截器

/**
 * @Description: 用户登录拦截器
 **/

@Component
public class LoginUserInterceptor implements HandlerInterceptor {

    public static ThreadLocal<MemberRespVo> loginUser = new ThreadLocal<>();

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        String uri = request.getRequestURI();
        AntPathMatcher antPathMatcher = new AntPathMatcher();
        boolean match = antPathMatcher.match("/member/**", uri);
 
        System.out.println("match: "+match);
        if (match) {
            return true;
        }
        HttpSession session = request.getSession();
        //获取登录的用户信息
        MemberRespVo attribute = (MemberRespVo) session.getAttribute(AuthServerConstant.LOGIN_USER);
        if (attribute != null) {
            //把登录后用户的信息放在ThreadLocal里面进行保存
            loginUser.set(attribute);
            return true;
        } else {
            //未登录，返回登录页面
            request.getSession().setAttribute("msg", "请先进行登录");
             response.sendRedirect("http://auth.gulimall.com/login.html");
            return false;
        }
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception{}
}

b.配置类使用拦截器

/**
 * @Description: MemberWebConfig
 **/

@Configuration
public class MemberWebConfig implements WebMvcConfigurer {

    @Autowired
    private LoginUserInterceptor loginUserInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(loginUserInterceptor).addPathPatterns("/**");
    }
}

5.2.4).添加Sesion、redis依赖及配置

        <!--整合spring-session完成Session共享问题-->
        <dependency>
            <groupId>org.springframework.session</groupId>
            <artifactId>spring-session-data-redis</artifactId>
        </dependency>
        <!--spring整合redis依赖,lettuce容易内存溢出,使用jedis不会-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>io.lettuce</groupId>
                    <artifactId>lettuce-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <!--导入jedis依赖-->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
        </dependency>

#session配置
spring.session.store-type=redis
#配置redis
spring.redis.host=192.168.56.10

启动开启session功能

@EnableRedisHttpSession //开启Sesion功能

5.2.5).添加springSession配置类

/**
 * @Description: springSession配置类
 **/

@Configuration
public class GulimallSessionConfig {

    @Bean
    public CookieSerializer cookieSerializer() {

        DefaultCookieSerializer cookieSerializer = new DefaultCookieSerializer();

        //放大作用域
        cookieSerializer.setDomainName("gulimall.com");
        cookieSerializer.setCookieName("GULISESSION");

        return cookieSerializer;
    }


    @Bean
    public RedisSerializer<Object> springSessionDefaultRedisSerializer() {
        return new GenericJackson2JsonRedisSerializer();
    }

}

5.2.6).测试成功

支付成功，跳转到支付列表页orderList.html

5.2.7).渲染支付列表页-member项目

a.controller-分页

@Controller
public class MemberWebController {
    @Autowired
    OrderFeignService orderFeignService;
    @GetMapping("/memberOrder.html")
    public String memberOrderPage(@RequestParam(value = "pageNum",defaultValue = "1") Integer pageNum,
                                  Model model) {
        //查出当前登录的用户的所有订单列表数据
        HashMap<String, Object> page = new HashMap<>();
        page.put("page",pageNum.toString());
        //防止cookie丢失，使用feign配置。添加GuliFeignConfig
        R r = orderFeignService.listWithItem(page);
        System.out.println("r: "+ JSON.toJSONString(r));
        model.addAttribute("orders",r);
         return "orderList";
    }
}

b.feign接口

@FeignClient("gulimall-order")
public interface OrderFeignService {
    //查询当前用户的订单信息
    @PostMapping("/order/order/listWithItem")
    public R listWithItem(@RequestBody Map<String, Object> params);
}

c.远程order的控制器

    //查询当前用户的订单信息
    @PostMapping("/listWithItem")
    public R listWithItem(@RequestBody Map<String, Object> params) {
        PageUtils page = orderService.queryPageWithItem(params);
        return R.ok().put("page", page);
    }

d.order实现类

    //订单列表
    @Override
    public PageUtils queryPageWithItem(Map<String, Object> params) {
        MemberRespVo memberRespVo = LoginUserInterceptor.loginUser.get();

        IPage<OrderEntity> page = this.page(
                new Query<OrderEntity>().getPage(params),
                new QueryWrapper<OrderEntity>().eq("member_id", memberRespVo.getId()).orderByDesc("id")
        );

        List<OrderEntity> order_sn = page.getRecords().stream().map(order -> {
            List<OrderItemEntity> itemEntities = orderItemService.list(new QueryWrapper<OrderItemEntity>().eq("order_sn", order.getOrderSn()));
            order.setItemEntities(itemEntities);
            return order;
        }).collect(Collectors.toList());
        page.setRecords(order_sn);

        return new PageUtils(page);
    }

e.页面渲染

<table class="table" th:each="order:${orders.page.list}">
                <tr>
                    <td colspan="7" style="background:#F7F7F7">
                        <span style="color:#AAAAAA">2017-12-09 20:50:10</span>
                        <span><ruby style="color:#AAAAAA">订单号:</ruby> [[${order.orderSn}]]</span>
                        <span>谷粒商城<i class="table_i"></i></span>
                        <i class="table_i5 isShow"></i>
                    </td>
                </tr>
                <tr class="tr" th:each="item,itemStat:${order.itemEntities}">
                    <td colspan="3" style="border-right: 1px solid #ccc">

3.支付宝支付成功后，页面跳转

3.1 介绍

支付宝支付成功后，页面跳转。
支付宝提供2种方式，同步回调（return）、异步回调(notify)
2中的controller使用同步回调（return）
http://member.gulimall.com/memberOrder.html?charset=utf-8&out_trade_no=202106061355374811401417473772761089&method=alipay.trade.page.pay.return&total_amount=35994.00&sign=CmjQsEWr95qkJJZfTGvNpltGQq1%2BJlRprtIN50shPthVZ7UMUwmamz0XJDN6PQEiaL1C4ztcLH3dMtKnpBnUjQUhIeAM5LxmfT9Xpvg6mxMNHuqImlDJAwHd1JciQJwutgdwphIP%2B%2BZ9LmUihjK5%2F1LBja3s9%2BEMX5KfHIwIWSlZGfEJOFN1FHHyuPZUuLLW07%2BtIWwSn9qc6uijXOzFjqEy1AB5eflHk5L9RRUAdOMEOgMhNn2o6Dq%2FY7TxcGSLZ9FM%2Beilo%2BZNQupsWVewehv2xpBP%2FLWEtmjqTI85eNSBnuxXJLZ1LCoKkRjUM5CFaOvgFun8EeeGWsQvljDtIw%3D%3D&trade_no=2021060622001419170503479161&auth_app_id=2021000117668106&version=1.0&app_id=2021000117668106&sign_type=RSA2&seller_id=2088621955877431&timestamp=2021-06-06+13%3A56%3A34
地址栏数据太多，同步回调（return）不安全。

3.2 异步回调(notify)

在这里插入图片描述
怎么操作呢？使用异步通知内网穿透

4.异步通知内网穿透环境搭建

异步通知说明 https://opendocs.alipay.com/open/270/105902

4.1 修改order的AlipayTemplate

private String notify_url = “http://vqdvprum3r.52http.tech/payed/notify”;

4.2 order创建订单支付成功的监听器

1).修改内外穿透地址

实现内网穿透的十几种方法
一：浙西云
浙西云开发普通 https://cloud.zhexi.tech/xd/remote/mapping
微信扫描登录，需要购买
在这里插入图片描述

2).内外穿透流程

在这里插入图片描述

a).修改niginx配置文件

解决： host头不匹配问题
在这里插入图片描述

重启redis，docker restart nginx

3).异步通知说明

异步通知说明 https://opendocs.alipay.com/open/270/105902

a.添加支付异步数据的vo

/支付的异步数据

@ToString
@Data
public class PayAsyncVo {
    private String gmt_create;
    private String charset;
    private String gmt_payment;
    private Date 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
}

b.修改 OrderPayedListener

/**
 * @Description: 订单支付成功监听器
 **/

@RestController
public class OrderPayedListener {

    @Autowired
    private OrderService orderService;

    @Autowired
    private AlipayTemplate alipayTemplate;

    @PostMapping(value = "/payed/notify")

    public String handleAlipayed(PayAsyncVo vo, HttpServletRequest request) throws AlipayApiException, UnsupportedEncodingException {
        // 只要收到支付宝的异步通知，说明支付成功。返回 success， 支付宝便不再通知
        // 获取支付宝POST过来反馈信息

        //TODO 需要验签。(验证是不是支付宝发送的数据)
        Map<String,String> params = new HashMap<String,String>();
        Map<String,String[]> requestParams = request.getParameterMap();
        System.out.println("支付宝通知到位了");
        for (Iterator<String> iter = requestParams.keySet().iterator(); iter.hasNext();) {
            String name = (String) iter.next();
            String[] values = (String[]) requestParams.get(name);
            String valueStr = "";
            for (int i = 0; i < values.length; i++) {
                valueStr = (i == values.length - 1) ? valueStr + values[i]
                        : valueStr + values[i] + ",";
            }
            //乱码解决，这段代码在出现乱码时使用
//            valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
            params.put(name, valueStr);
        }

        boolean signVerified = AlipaySignature.rsaCheckV1(params, alipayTemplate.getAlipay_public_key(), alipayTemplate.getCharset(), alipayTemplate.getSign_type()); //调用SDK验证签名

        if (signVerified) {
            System.out.println("签名验证成功...");
            //去修改订单状态
            String result = orderService.handlePayResult(vo);
            return result;
        } else {
            System.out.println("签名验证失败...");
            return "error";
        }
    }
}

c.orderService的 handlePayResult

//处理支付宝的支付结果
    @Override
    public String handlePayResult(PayAsyncVo vo) {
        //1.保存交易流水
        PaymentInfoEntity payment = new PaymentInfoEntity();
        payment.setAlipayTradeNo(vo.getTrade_no());
        payment.setOrderSn(vo.getOut_trade_no());
        payment.setPaymentStatus(vo.getTrade_status());
        payment.setCallbackTime(vo.getNotify_time());
        paymentInfoService.save(payment);

        //2.修改订单的状态信息
        if (vo.getTrade_status().equals("TRADE_SUCCESS") || vo.getTrade_status().equals("TRADE_FINISHED")) {
            //支付成功状态
            String outTradeNo = vo.getOut_trade_no();
            this.baseMapper.updateOrderStatus(outTradeNo, OrderStatusEnum.PAYED.getCode());
        }
        return "success";
    }

至此支付完成

5.收单

在这里插入图片描述
使用收单，怎么收单？

5.1. 如何收单一

订单在支付页面，不支付。当订单超时，订单自动关闭后。再支付，会发生啥？
在这里插入图片描述
API 列表 https://opendocs.alipay.com/open/270/105900

在这里插入图片描述
alipay.trade.page.pay(统一收单下单并支付页面接口)

设置超时时间
在这里插入图片描述

1).AlipayTemplate添加超时设置

可以设为30m
private String timeout=“30m”;
在这里插入图片描述

2).测试与结果

订单在支付页面，不支付。当订单超时，订单自动关闭后。再支付，结果：
在这里插入图片描述

5.2. 如何收单二

订单完成解锁。正在解锁库存时，异步通知才到。怎么办？手动调用收单
在这里插入图片描述
alipay.trade.close(统一收单交易关闭接口)

此处不做了，自动适应5.1的自动收单功能

	//获得初始化的AlipayClient
	AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.gatewayUrl, AlipayConfig.app_id, AlipayConfig.merchant_private_key, "json", AlipayConfig.charset, AlipayConfig.alipay_public_key, AlipayConfig.sign_type);
	
	//设置请求参数
	AlipayTradeCloseRequest alipayRequest = new AlipayTradeCloseRequest();
	//商户订单号，商户网站订单系统中唯一订单号
	String out_trade_no = new String(request.getParameter("WIDTCout_trade_no").getBytes("ISO-8859-1"),"UTF-8");
	//支付宝交易号
	String trade_no = new String(request.getParameter("WIDTCtrade_no").getBytes("ISO-8859-1"),"UTF-8");
	//请二选一设置
	
	alipayRequest.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\"," +"\"trade_no\":\""+ trade_no +"\"}");
	
	//请求
	String result = alipayClient.execute(alipayRequest).getBody();
