This article will explain in detail the example analysis of mybatis plus automatic generator for you. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Parsing of mybatis plus automatic Generator

Use this to generate entity service controller layers very quickly

1. Add dependency

The dependencies of the template engine should also be imported, otherwise the operation will report an error.

Com.baomidou mybatis-plus-generator 3.3.1.tmp org.freemarker freemarker 2.3.30 2. Write a class as an entry to the automatic generator

When you are here, be sure to copy the import package, otherwise it is easy to make mistakes.
