12306系统会员基础功能的实现-526互联

乘车人表的设计

新增/修改时间保存到毫秒

drop table if exists `passenger`;
create table `passenger` (
  `id` bigint not null comment 'id',
  `member_id` bigint not null comment '会员id',
  `name` varchar(20) not null comment '姓名',
  `id_card` varchar(18) not null comment '身份证',
  `type` char(1) not null comment '旅客类型|枚举[PassengerTypeEnum]',
  `create_time` datetime(3) comment '新增时间',
  `update_time` datetime(3) comment '修改时间',
   primary key (`id`),
   index `member_id_index` (`member_id`)
) engine=innodb default charset=utf8mb4 comment='乘车人';

用generator-config-member.xml生成持久层代码

<table tableName="passenger" domainObjectName="Passenger"/>

打开方式Maven--generator--Plugins--mybatis-generator--双击

增加乘车人类型枚举

10     ADULT("1", "成人"),

12     STUDENT("3", "学生");
13 
14     private String code;
15 
16     private String desc;
17 
18     PassengerTypeEnum(String code, String desc) {
19         this.code = code;
20         this.desc = desc;
21     }
