还在为不会写代码生成工具而发愁？可以利用此项目进行学习，直接用，直接二次开发，足以满足小项目了，又快又狠。
目的：极大的增强代码生成工具的可移植性，快速完成小型外包项目，走到哪儿用到哪儿🍻
灵感源于 xxl-code-generator.
可根据项目的需要，量身定制一套代码生成工具，虽然不能生成list.html、add.html、edit.html，可以根据自己的模板引擎和UI库在结合此示例，自行安排一套属于自己的代码生成工具。
如果你的项目是多模块的，你可以直接将 fun-generator 模块附加进去。
为什么不一次自动生成全部表的代码？
原因待我细细道来：
② 开箱即用！不用连接数据库!不用连接数据库!不用连接数据库!
① 我们在开发的过程中，大家都知道数据库都是难免会更改字段的，一般小公司是没有dba的，
所以这个情况免不了🙃。一次生成一张表的代码，可以极大的降低耦合性与修改的不便性。就算
修改单张表的字段后，即可针对这个马上重新生成代码来覆盖之前的代码。
③ 使用sql生成的原因是为了方便结合Flyway，使之更为便捷。
