主要对支付宝的开放平台对接的使用，验签收单有了一定的连接。

视频中的nginx配置：

我没有动这块，还是走的阿里云：

代码具体如下：

@ConfigurationProperties(prefix = "alipay")
@Component

}

进行验签：

/*** @author WGR* @create 2020/8/13 -- 0:03*/
@RestController
public class OrderPayedListener {@AutowiredOrderService orderService;@PostMapping("/payed/notify")@SneakyThrowspublic String handleAlipayed(PayAsyncVo vo, HttpServletRequest request){
//        Map<String, String[]> parameterMap = request.getParameterMap();
//        for (String key : parameterMap.keySet()){
//            String value = request.getParameter(key);
//            System.out.println("参数名："+key+"==>参数值："+value);
//        }//获取支付宝GET过来反馈信息Map<String,String> params = new HashMap<String,String>();Map<String,String[]> requestParams = request.getParameterMap();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.alipay_public_key, AlipayTemplate.charset, AlipayTemplate.sign_type); //调用SDK验证签名//——请在这里编写您的程序（以下代码仅作参考）——if(signVerified) {System.out.println("验签成功");String reuslt =  orderService.handlePayResult(vo);return reuslt;}else {System.out.println("验签失败");return "error";}}
}

需要放行：

@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {String uri = request.getRequestURI();AntPathMatcher antPathMatcher = new AntPathMatcher();boolean match = antPathMatcher.match("/order/order/status/**", uri);boolean match1 = antPathMatcher.match("/payed/notify", uri);if(match || match1){return true;}MemberRespVo attribute = (MemberRespVo)request.getSession().getAttribute(AuthServerConstant.LOGIN_USER);if(attribute !=null){loginUser.set(attribute);return true;}else{request.getSession().setAttribute("msg","请先进行登录");response.sendRedirect("http://auth.gulimall.com/login.html");return false;}}

@Overridepublic String handlePayResult(PayAsyncVo vo) {//1.保存交易流水PaymentInfoEntity infoEntity = new PaymentInfoEntity();infoEntity.setAlipayTradeNo(vo.getTrade_no());infoEntity.setOrderSn(vo.getOut_trade_no());infoEntity.setPaymentStatus(vo.getTrade_status());infoEntity.setCallbackTime(vo.getNotify_time());paymentInfoService.save(infoEntity);//2.修改订单的状态信息if(vo.getTrade_status().equals("TRADE_SUCCESS") || vo.getTrade_status().equals("TRADE_FINISHED")){String outTradeNo = vo.getOut_trade_no();this.baseMapper.updateOrderStatus(outTradeNo,OrderStatusEnum.PAYED.getCode());}return "success";}@Overridepublic 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);}
