4.说明

此时Maven刷新后父工程的pom文件中依旧爆红 ,这是正常的等后续子工程加入后爆红消失。
maven的dependencyManagement位于最顶级的父pom中,主要用于版本管理，而不是直接添加依赖关系

5.数据库

创建db2024的数据库

sql 复制代码

DROP TABLE IF EXISTS `t_pay`;

CREATE TABLE `t_pay` (
  `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `pay_no` VARCHAR(50) NOT NULL COMMENT '支付流水号',
  `order_no` VARCHAR(50) NOT NULL COMMENT '订单流水号',
  `user_id` INT(10) DEFAULT '1' COMMENT '用户账号ID',
  `amount` DECIMAL(8,2) NOT NULL DEFAULT '9.9' COMMENT '交易金额',
  `deleted` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT '删除标志，默认0不删除，1删除',
  `create_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='支付交易表';

 
-- 插入数据
INSERT INTO t_pay(pay_no,order_no) VALUES('pay17203699','6544bafb424a');


SELECT * FROM t_pay;
