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 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
商家信息
商家账号ntuxoj8103@sandbox.com

证件类型身份证(IDENTITY_CARD)
证件号码824246193201221687
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
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
e.修改orderList.html静态资源的路径
f.修改域名
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

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×tamp=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)
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
2).内外穿透流程
a).修改niginx配置文件
解决： host头不匹配问题
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
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？
API 列表 https://opendocs.alipay.com/open/270/105900
alipay.trade.page.pay(统一收单下单并支付页面接口)
设置超时时间
1).AlipayTemplate添加超时设置
可以设为30m
private String timeout=“30m”;
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：
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
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();
