我是靠谱客的博主柔弱鸵鸟，最近开发中收集的这篇文章主要介绍springboot+mybaitsplus 代码生成器springboot+mybatisplus 代码生成器，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

测试类

public class textPlus {
public static void main(String[] args) {
CreateAoutGenerator createAoutGenerator=new CreateAoutGenerator();
AutoGenerator mpg=createAoutGenerator.CreateGenerator();
mpg.execute();
}
}
