刚刚开始学习本项目，单表的查询通过mbg生成，多表的查询怎么自动生成？

我注意到，mbg项目中将所有表的基本单表查询和更新通过mybatis generator工具实现了自动生成

除此之外，我还发现在admin项目中，src/main/resources/dao目录下还有一些手写的SQL，这些SQL对应的Java Dao和Dto类也是通过自动化工具自动生成的吗？

如果是，自动化生成的相关配置是否在项目中有所体现？

谢谢！

FK constraint

在阅读这里的时候http://www.macrozheng.com/#/database/mall_database_overview，结构图里是有画Foreign Key的，但是使用这里的script： https://github.com/macrozheng/mall/blob/master/document/sql/mall.sql 所创建的数据库里并没有任何的FK，这个是什么原因呢？

项目采用mybatis-plus是个败笔

项目中的分页采用mybatis-plus分页，针对复杂查询条件，且查询条件和数据列大部分都不一致时，这个框架会输出很多非必要数据，如果项目再引入mybatisHelper分页插件，两个分页插件会冲突，而且作者项目中使用的是plus，而在文档中写的是helper来做引导，很明显根本自己没有尝试同时引入两个分页插件
