第三步：发送检查支付结果的消息队列
@Autowired
private OmsOrderSettingMapper orderSettingMapper;
@Autowired
private AmqpTemplate amqpTemplate;
/**
* 发送检查支付结果的消息队列
* @param orderSn
* @param count
*/
@Override
public void sendDelayPaymentCheck(String orderSn, int count) {
//获取订单超时时间
OmsOrderSetting orderSetting = orderSettingMapper.selectByPrimaryKey(1L);
long delayTimes = orderSetting.getNormalOrderOvertime() * 60 * 1000;
HashMap hashMap = new HashMap<>();
hashMap.put("out_trade_no",orderSn);
hashMap.put("count",count);
//给延迟队列发送消息
amqpTemplate.convertAndSend(QueueEnum.QUEUE_PAY_CANCEL.getExchange(), QueueEnum.QUEUE_PAY_CANCEL.getRouteKey(), hashMap, new MessagePostProcessor() {
@Override
public Message postProcessMessage(Message message) throws AmqpException {
//给消息设置延迟毫秒值
message.getMessageProperties().setExpiration(String.valueOf(delayTimes));
return message;
}
});
} 第四步：处理发送检查支付结果的消息队列
package com.macro.mall.portal.component;
import com.macro.mall.model.PaymentInfo;
import com.macro.mall.portal.service.PaymentService;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.HashMap;
/**
* 支付的处理者
*/
@Component
@RabbitListener(queues = "mall.pay.cancel")
public class PayReceiver {
@Autowired
PaymentService paymentService;
@RabbitHandler
public void handle(HashMap mapMessage){
try {
String outTradeNo = mapMessage.get("out_trade_no").toString();
int count = Integer.parseInt(mapMessage.get("count").toString());
// 如果没有支付成功，再次发送延迟检查队列
if (count > 0) {
// 进行支付状态检查
System.out.println("正在进行第" + (6 - count) + "支付结果次检查");
//调用alipayClient接口，根据out_trade_no查询支付信息
PaymentInfo paymentInfo = paymentService.checkPaymentResult(outTradeNo);
Thread thread = new Thread();
thread.start();
Thread.sleep(10000);
//判断是否已经支付成功
if (paymentInfo.getPaymentStatus()!=null&&(paymentInfo.getPaymentStatus().equals("TRADE_SUCCESS") || paymentInfo.getPaymentStatus().equals("TRADE_FINISHED"))) {
// 交易成功或者失败，记录交易状态
System.out.println("检查交易结果成功，记录交易状态。。。");// 修改支付的状态信息
// 修改支付信息
boolean b = paymentService.checkPaymentStatus(outTradeNo);
if(!b){
//修改为已支付
paymentService.updatePayment(paymentInfo.getCallbackContent(),outTradeNo,paymentInfo.getAlipayTradeNo());
// 发送系统消息，出发并发商品支付业务消息队列
paymentService.sendPaymentSuccess(paymentInfo.getOutTradeNo(),paymentInfo.getPaymentStatus(),paymentInfo.getAlipayTradeNo());
}
} else {//未支付
// 再次进行延迟检查
System.out.println("正在进行第" + (6 - count) + "支付结果次检查，检查用户尚未付款成功，继续巡检");
paymentService.sendDelayPaymentCheck(outTradeNo, count - 1);
}
} else {
System.out.println("支付结果次检查次数耗尽，支付未果。。。");
}
} catch (Exception e) {
}
}
}
第五步：调用alipayClient接口，根据out_trade_no查询支付信息
@Autowired
AlipayClient alipayClient;
/**
* 进行支付状态检查
* @param outTradeNo
* @return
*/
@Override
public PaymentInfo checkPaymentResult(String outTradeNo) {
PaymentInfo paymentInfo = new PaymentInfo();
// 调用alipayClient接口，根据out_trade_no查询支付状态
AlipayTradeQueryRequest request = new AlipayTradeQueryRequest();
Map mapString = new HashMap();
mapString.put("out_trade_no",outTradeNo);
String s = JSON.toJSONString(mapString);
request.setBizContent(s);
AlipayTradeQueryResponse response = null;
try {
response = alipayClient.execute(request);
} catch (AlipayApiException e) {
e.printStackTrace();
}
// 等待付款、付款成功、付款失败、已经结束
paymentInfo.setCallbackTime(new Date());
paymentInfo.setOutTradeNo(outTradeNo);
paymentInfo.setCallbackContent(response.getMsg());
if(response.isSuccess()){
System.out.println("交易已经创建");
paymentInfo.setPaymentStatus(response.getTradeStatus());
paymentInfo.setAlipayTradeNo(response.getTradeNo());
} else {
System.out.println("交易未创建");
}
return paymentInfo;
} 第六步：发送系统消息，出发并发商品支付业务消息队列
@Autowired
private OmsOrderSettingMapper orderSettingMapper;
@Autowired
private AmqpTemplate amqpTemplate;
/**
* 发送系统消息，出发并发商品支付业务消息队列
* @param outTradeNo
* @param paymentStatus
* @param tradeNo
*/
@Override
public void sendPaymentSuccess(String outTradeNo, String paymentStatus, String tradeNo) {
HashMap hashMap = new HashMap<>();
hashMap.put("outTradeNo",outTradeNo);
hashMap.put("paymentStatus",paymentStatus);
hashMap.put("tradeNo",tradeNo);
OmsOrderSetting orderSetting = orderSettingMapper.selectByPrimaryKey(1L);
long delayTimes = orderSetting.getNormalOrderOvertime() * 60 * 1000;
//给延迟队列发送消息
amqpTemplate.convertAndSend(QueueEnum.QUEUE_PAYMENT_SUCCESS_CANCEL.getExchange(), QueueEnum.QUEUE_PAYMENT_SUCCESS_CANCEL.getRouteKey(), hashMap, new MessagePostProcessor() {
@Override
public Message postProcessMessage(Message message) throws AmqpException {
//给消息设置延迟毫秒值
message.getMessageProperties().setExpiration(String.valueOf(delayTimes));
return message;
}
});
} 第七步：处理发送系统消息，出发并发商品支付业务消息队列
package com.macro.mall.portal.component;
import com.macro.mall.portal.service.OmsOrderService;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.HashMap;
/**
* 支付成功的处理者
*/
@Component
@RabbitListener(queues = "mall.paysuccess.cancel")
public class PaySuccessReceiver {
@Autowired
private OmsOrderService orderService;
@RabbitHandler
public void handle(HashMap mapMessage){
String outTradeNo = mapMessage.get("outTradeNo").toString();
String trackingNo = mapMessage.get("tradeNo").toString();
String paymentStatus = mapMessage.get("paymentStatus").toString();
// 消费代码
orderService.updateOrder(outTradeNo,paymentStatus,trackingNo);
// 发送一个订单成功的消息队列，由库存系统消费(或者调用库存接口)
orderService.sendOrderResult(outTradeNo);
}
}
第八步：发送一个订单成功的消息队列，由库存系统消费(或者调用库存接口)
@Autowired
private OmsOrderItemMapper omsOrderItemMapper;
@Autowired
private AmqpTemplate amqpTemplate;
/**
* 发送一个订单成功的消息队列，由库存系统消费(或者调用库存接口)
* @param outTradeNo
*/
@Override
public void sendOrderResult(String outTradeNo) {
OmsOrderItemExample omsOrderItemExample = new OmsOrderItemExample();
OmsOrderItemExample.Criteria criteria = omsOrderItemExample.createCriteria();
criteria.andOrderSnEqualTo(outTradeNo);
List omsOrderItems = omsOrderItemMapper.selectByExample(omsOrderItemExample);
OmsOrderItem omsOrder = omsOrderItems.get(0);
Long productId = omsOrder.getProductId();
HashMap objectObjectHashMap = new HashMap<>();
objectObjectHashMap.put("productId",productId);
//给延迟队列发送消息
amqpTemplate.convertAndSend(QueueEnum.QUEUE_STOCK_QUEUE.getExchange(), QueueEnum.QUEUE_STOCK_QUEUE.getRouteKey(),objectObjectHashMap, new MessagePostProcessor() {
@Override
public Message postProcessMessage(Message message) throws AmqpException {
//给消息设置延迟毫秒值
message.getMessageProperties().setExpiration(String.valueOf(0));
return message;
}
});
} 第九步：处理发送一个订单成功的消息队列，由库存系统消费(或者调用库存接口)
package com.macro.mall.portal.component;
import com.macro.mall.portal.service.PmsSkuStockService;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.HashMap;
@Component
@RabbitListener(queues = "mall.stock.cancel")
public class StockReserve {
@Autowired
private PmsSkuStockService pmsSkuStockService;
@RabbitHandler
public void handle(HashMap productId){
//根据订单编号查询该订单的商品数量
Integer productQuantity = pmsSkuStockService.getProductQuantity(productId);
//根据商品id减卖家库存表的库存
pmsSkuStockService.updateOrderStock(productQuantity,productId.get("productId"));
}
}
