【背景】
之前就接触过mybatis相关的逆向工程生成对应单表的mapping和pojo，最近在做项目的时候也有相关的需求用到了，所以就结合之前学的Spring Cloud将其封装成了一个jar，以后再用的时候简单配置一下，就可以用了很是方便。
【简介】
为了方便使用我将它提交到了github上去，可是我打的jar文件比较大，然后，有想看源码的朋友可以访问我的github：https://github.com/mark6688/mybatis_reverse_engineering.git
又想到为人民服务的理念，所以将自己生成的可执行jar文件上传到了云盘，拿走不谢，地址：https://pan.baidu.com/s/1elue0lzFnumumj06A-_GlA

又考虑到，要是针对于大牛们只想看看代码，我也就将自己的几个关键文件中的内容贴到下面了：

【总结】
对于这些公共东西的抽象，以及通过思想的抽象将它们封装成相关的小工具，这样的体验，总是带给自己愉快的感觉，让自己未来的路有了更加充实的力量。
