数据库准备

  `user_id` int(11) NOT NULL AUTO_INCREMENT COMMENT ‘自增主键‘,
  `user_name` varchar(20) DEFAULT NULL COMMENT ‘姓名‘,

  `password` varchar(11) DEFAULT NULL COMMENT ‘密码‘,
  `last_visit` datetime DEFAULT NULL COMMENT ‘最后一次登陆时间‘,
  `last_ip` varchar(11) DEFAULT NULL COMMENT ‘最后一次登陆ip‘,
  PRIMARY KEY (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT=‘t01模块的用户表‘

CREATE TABLE `t01_login_log` (
