完美集成lombok，swagger的代码生成工具，让你不再为繁琐的注释和简单的接口实现而烦恼：entity集成，格式校验，swagger; dao自动加@ mapper，service自动注释和依赖; 控制器实现单表的增副改查，并实现swaggers的api文档。

2.1.0版本是未集成Mybatis-plus版本——源码分支master

<dependency>
    <groupId>com.github.flying-cattle</groupId>
    <artifactId>mybatis-dsc-generator</artifactId>
    <version>2.1.0.RELEASE</version>

3.0.0版本是集成了Mybatis-plus版本——源码分支mybatisPlus

    <version>2.1.0.RELEASE</version>
</dependency>

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）。

生成的实体类

生成方法参考源码中的： https://github.com/flying-cattle/mybatis-dsc-generator/blob/mybatisPlus/src/main/java/com/github/mybatis/fl/test/TestMain.java

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();
}
