第一版sql腳本

src/main/resources/db/migration/V1__sys_dept.sql

SET FOREIGN_KEY_CHECKS=0;-- ------------------------------ Table structure for sys_dept-- ----------------------------DROP TABLE IF EXISTS `sys_dept`;CREATE TABLE `sys_dept` ( `dept_id` int(20) NOT NULL AUTO_INCREMENT, `name` varchar(50) DEFAULT NULL COMMENT ’部門(mén)名稱(chēng)’, `sort` int(11) DEFAULT ’0’ COMMENT ’排序’, `create_time` datetime DEFAULT NULL COMMENT ’創(chuàng)建時(shí)間’, `update_time` datetime DEFAULT NULL COMMENT ’修改時(shí)間’, `del_flag` char(1) DEFAULT ’0’ COMMENT ’是否刪除 -1：已刪除 0：正常’, `parent_id` int(11) DEFAULT NULL, PRIMARY KEY (`dept_id`)) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT=’部門(mén)管理’;

第二版sql腳本

src/main/resources/db/migration/V1.1__sys_dept.sql

INSERT INTO `sys_dept` VALUES (1, ’總經(jīng)辦’, 0, ’2020-03-13 13:13:16’, ’2020-03-13 13:14:31’, ’0’, 0);INSERT INTO `sys_dept` VALUES (2, ’行政中心’, 1, ’2020-03-13 13:13:30’, NULL, ’0’, 1);INSERT INTO `sys_dept` VALUES (3, ’技術(shù)中心’, 2, ’2020-03-13 13:14:55’, NULL, ’0’, 1);INSERT INTO `sys_dept` VALUES (4, ’運(yùn)營(yíng)中心’, 3, ’2020-03-13 13:15:15’, NULL, ’0’, 1);INSERT INTO `sys_dept` VALUES (5, ’研發(fā)中心’, 5, ’2020-03-13 13:15:34’, NULL, ’0’, 3);INSERT INTO `sys_dept` VALUES (6, ’產(chǎn)品中心’, 6, ’2020-03-13 13:15:49’, NULL, ’0’, 3);INSERT INTO `sys_dept` VALUES (7, ’測(cè)試中心’, 7, ’2020-03-13 13:16:02’, NULL, ’0’, 3);

項(xiàng)目配置文件，主要是dataSource，flyway的采用約定值

src/main/resources/application.properties

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/fly_way?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8&allowPublicKeyRetrieval=truespring.datasource.username=rootspring.datasource.password=rootspring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
