数据表结构样式
CREATE TABLE `user` ( `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'ID', `login_name` varchar(40) DEFAULT NULL COMMENT '登录名', `password` varchar(100) NOT NULL COMMENT '秘密', `nickname` varchar(50) NOT NULL COMMENT '昵称', `type` int(10) unsigned DEFAULT NULL COMMENT '类型', `state` int(10) unsigned NOT NULL DEFAULT '1' COMMENT '状态：-1失败，0等待,1成功', `note` varchar(255) DEFAULT NULL COMMENT '备注', `create_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间', `update_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间', `update_uid` bigint(20) DEFAULT '0' COMMENT '修改人用户ID', `login_ip` varchar(50) DEFAULT NULL COMMENT '登录IP地址', `login_addr` varchar(100) DEFAULT NULL COMMENT '登录地址', PRIMARY KEY (`id`), UNIQUE KEY `login_name` (`login_name`) ) ENGINE=InnoDB AUTO_INCREMENT=13 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
要求必须有表注释，要求必须有主键为id,所有字段必须有注释（便于生成 java 注释swagger等）。

如果你生成的分页的方法不能分页：根据官方提升，记得在启动类中加入
@Bean
public PaginationInterceptor paginationInterceptor() {
return new PaginationInterceptor();
}

Since development first began on Spring in 2003, there's been a constant buzz about it in Java development publications and corporate IT departments. The reason is clear: Spring is a lightweight Java......一起来看看 《Spring》 这本书的介绍吧!
