本文是仿12306项目实战第(二)章——项目实现 的第五篇,本篇讲解该项目的核心功能——余票查询、车票预定功能的基础版开发,以及讲解项目与Nacos的集成
本章目录
一、核心功能介绍
二、增加余票信息表,生成代码
-
business.sql
drop table if exists `daily_train_ticket`; create table `daily_train_ticket` ( `id` bigint not null comment 'id', `date` date not null comment '日期', `train_code` varchar(20) not null comment '车次编号', `start` varchar(20) not null comment '出发站', `start_pinyin` varchar(50) not null comment '出发站拼音', `start_time` time not null comment '出发时间', `start_index` tinyint not null comment '出发站序|本站是整个车次的第几站', `end` varchar(20) not null comment '到达站', `end_pinyin` varchar(50) not null comment '到达站拼音', `end_time` time not null comment '到站时间', `end_index` tinyint not null comment '到站站序|本站是整个车次的第几站', `ydz` int not null comment '一等座余票', `ydz_price` decimal(8, 2) not null comment '一等座票价', `edz` int not null comment '二等座余票', `edz_price` decimal(8, 2) not null comment '二等座票价', `rw` int not null comment '软卧余票', `rw_price` decimal(8, 2) not null comment '软卧票价', `yw` int not null comment '硬卧余票', `yw_price` decimal(8, 2) not null comment '硬卧票价', `create_time` datetime(3) comment '新增时间', `update_time` datetime(3) comment '修改时间', primary key (`id`), unique key `date_train_code_start_end_unique` (`date`, `train_code`, `start`, `end`) ) engine=innodb default charset=utf8mb4 comment='余票信息';
实际12306用的是商业缓存软件来做的余票信息缓存,本项目用mysql新建临时表来代替缓存演示业务实现
-
修改generator-config-business.xml,生成持久层、前后端代码
<table tableName="daily_train_ticket" domainObjectName="DailyTrainTicket"/>
操作同之前
-
修改admin/package.json,加规则去除ESLint报错
"rules": { "vue/multi-word-component-names": 0, "no-undef": 0, "vue/no-unused-vars": 0 }
-
修改路由、侧边栏
操作同之前
-
测试
数据后续由定时任务填充
三、生成车次时初始化余票信息
-
给批量方法都加上@Transactional
虽然由于事务的传递性,外层有事务,内层方法也会是事务,但是规范点还是都加上事务注解
-
DailyTrainTicketService.java
逻辑:比如车站1——车站2——车站3,站站组合情况就有 1、2;1、3;2、3 三种,需要分别生成每种组合的余票信息
这里第一版 先解决站站组合逻辑,具体余票信息后面完善

测试
重新生成车次
五、为余票信息页面增加查询条件

测试
-
问题:用户端不需要根据车次查询,另外三个参数则必须输入
-
修改余票查询页面,查询的三个参数必输,去掉车次查询条件

七、增加订票页面并且实现车次信息传递
1.增加预订按钮,点击预订时,跳转到下单页面,并使用sessionStorage传递参数
-
order.vue
下单页面
<template> <div>{{ dailyTrainTicket }}</div> </template> <script> import {defineComponent} from 'vue'; export default defineComponent({ name: "order-view", setup() { const dailyTrainTicket = SessionStorage.get("dailyTrainTicket") || {}; console.log("下单的车次信息", dailyTrainTicket); return { dailyTrainTicket }; }, }); </script>

九、分解选座购票功能的前后端逻辑
12306规则:
- 只有全部是一等座或全部是二等座才支持选座
- 余票小于一定数量时,不允许选座(本项目以20为例)
构造两个重要的响应式变量:
// 0:不支持选座;1:选一等座;2:选二等座 const chooseSeatType = ref(0); // 选择的座位 // { // A1: false, C1: true,D1: false, F1: false, // A2: false, C2: false,D2: true, F2: false // } const chooseSeatObj = ref({});
最终购票tickets:
// seat可选,当无选座时,seat为空 [{ passengerId: 123, passengerType: "1", seatTypeCode: "1", passengerName: "张三", passengerIdCard: "12323132132", seat: "C1" }, { passengerId: 123, passengerType: "1", seatTypeCode: "1", passengerName: "李四", passengerIdCard: "12323132132", seat: "D2" }]
座位售卖详情,比如有ABCDE五个站,sell=0110,则AB未被购买,AC已被购买
后端购票逻辑,分成选座和不选座
不选座,以购买一等座为例:遍历一等座车厢,每个车厢从1号座位开始找,未被购买的,就选中它
选座,以购买两张一等座AB为例:遍历一等座车厢,每个车厢从1号座位开始找A列座位,未被购买的,就预选中它;再挑它旁边的B,如果也未被购买,则最终选中这两个座位,如果B已被购买,则回到第一步,继续找未被购买的A座。从第二个座位开始,需要计算和第一个座位的偏移值,可以减少循环,提高选座效率
举例:当选择A1和C2座位,遍历找到A1座位,索引为0,则C2不需要再遍历,直接计算出偏移值是5,即索引是5,看可以不可选就行了
十、订票页面增加选座效果
这节是前端的选座逻辑的实现
1.勾选乘客后,提交时,校验余票是否足够(前端校验不一定准,但前端校验可以减轻后端很多压力)
-
order.vue
const finishCheckPassenger = () => { console.log("购票列表:", tickets.value); if (tickets.value.length > 5) { notification.error({description: '最多只能购买5张车票'}); return; } // 校验余票是否充足,购票列表中的每个座位类型,都去车次座位余票信息中,看余票是否充足 // 前端校验不一定准,但前端校验可以减轻后端很多压力 // 注意:这段只是校验,必须copy出seatTypesTemp变量来扣减,用原始的seatTypes去扣减,会影响真实的库存 let seatTypesTemp = Tool.copy(seatTypes); for (let i = 0; i < tickets.value.length; i++) { let ticket = tickets.value[i]; for (let j = 0; j < seatTypesTemp.length; j++) { let seatType = seatTypesTemp[j]; // 同类型座位余票-1,这里扣减的是临时copy出来的库存,不是真正的库存,只是为了校验 if (ticket.seatTypeCode === seatType.code) { seatType.count--; if (seatType.count < 0) { notification.error({description: seatType.desc + '余票不足'}); return; } } } } console.log("前端余票校验通过"); // 弹出确认界面 visible.value = true; };
2.根据购票列表,计算出是否支持选座
只有都选择一等座或都选二等座,才可以支持选座
获取到选座类型后,如果是一等座得到一等座的选座对象,二等座得到二等座的选座对象,如果是不可选,选座对象为空

效果
十、增加确认订单表并生成前后端代码
-
新增表
sql/business.sql
这里的车票使用json类型,实际上也可以使用子表来做
drop table if exists `confirm_order`; create table `confirm_order` ( `id` bigint not null comment 'id', `member_id` bigint not null comment '会员id', `date` date not null comment '日期', `train_code` varchar(20) not null comment '车次编号', `start` varchar(20) not null comment '出发站', `end` varchar(20) not null comment '到达站', `daily_train_ticket_id` bigint not null comment '余票ID', `tickets` json not null comment '车票', `status` char(1) not null comment '订单状态|枚举[ConfirmOrderStatusEnum]', `create_time` datetime(3) comment '新增时间', `update_time` datetime(3) comment '修改时间', primary key (`id`), index `date_train_code_index` (`date`, `train_code`) ) engine=innodb default charset=utf8mb4 comment='确认订单';
-
ConfirmOrderStatusEnum
enum也是可以用lombok注解的
package com.neilxu.train.business.enums; public enum ConfirmOrderStatusEnum { INIT("I", "初始"), PENDING("P", "处理中"), SUCCESS("S", "成功"), FAILURE("F", "失败"), EMPTY("E", "无票"), CANCEL("C", "取消"); private String code; private String desc; ConfirmOrderStatusEnum(String code, String desc) { this.code = code; this.desc = desc; } @Override public String toString() { return "ConfirmOrderStatusEnum{" + "code='" + code + '\'' + ", desc='" + desc + '\'' + "} " + super.toString(); } public String getCode() { return code; } public void setCode(String code) { this.code = code; } public void setDesc(String desc) { this.desc = desc; } public String getDesc() { return desc; } }
-
修改generator-config-business.xml、ServerGenerator.java、EnumGenerator.java生成代码
操作同之前,注意是admin
-
修改路由、侧边栏
操作同之前,注意是admin
-
效果
十一、后端增加确认下单购票接口
这节整理下后端确认下单购票接口的逻辑
-
com.neilxu.train.business.req.ConfirmOrderTicketReq
package com.neilxu.train.business.req; import jakarta.validation.constraints.NotBlank; import jakarta.validation.constraints.NotNull; import lombok.Data; @Data public class ConfirmOrderTicketReq { /** * 乘客ID */ @NotNull(message = "【乘客ID】不能为空") private Long passengerId; /** * 乘客票种 */ @NotBlank(message = "【乘客票种】不能为空") private String passengerType; /** * 乘客名称 */ @NotBlank(message = "【乘客名称】不能为空") private String passengerName; /** * 乘客身份证 */ @NotBlank(message = "【乘客身份证】不能为空") private String passengerIdCard; /** * 座位类型code */ @NotBlank(message = "【座位类型code】不能为空") private String seatTypeCode; /** * 选座,可空,值示例:A1 */ private String seat; }
-
ConfirmOrderSaveReq.java ——> ConfirmOrderDoReq.java
