Example Analysis of mybatis-plus Code Generator configuration
This article mainly introduces the mybatis-plus code generator configuration example analysis, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.
Recently, when I was playing with a project, I found that I wasted a lot of time writing ~ so I thought of the code generator, mybatis-plus, which I used once before, and then reimplemented it.
Just make sure to modify the corresponding configuration.
Dependence:
Com.baomidou mybatis-plus-boot-starter 2.2.0 mysql mysql-connector-java 5.1.47 freemarker freemarker 2.3.8
Code:

Build a project and drop it, modify the relevant configuration, and run is done.
Thank you for reading this article carefully. I hope the article "sample Analysis of mybatis-plus Code Generator configuration" shared by the editor will be helpful to you. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
