springboot 集成
引入pom
主要是build部分

/generatorConfiguration生成代码
创建表
CREATE TABLE base_user (user_id bigint(20) NOT NULL AUTO_INCREMENT COMMENT 用户ID,tenant_id int(11) DEFAULT NULL COMMENT 租户id,user_name varchar(30) DEFAULT COMMENT 用户昵称,remark varchar(500) DEFAULT NULL COMMENT 备注,PRIMARY KEY (user_id)
) ENGINEInnoDB DEFAULT CHARSETutf8mb4 COMMENT用户信息表;在项目的maven中双击生成代码插件
生成的类
完成。
