mybaits两步生成代码+实例代码
作者：互联网
最近对自动生成代码有些许研究，上一篇是mybaits-plus，该文章是mybaits自动生成代码说明+实例代码，快点关注吧后期更精彩，如有问题可以关注讨论。
概述：
1、
在mybatis-generator-config.xml 配置相关数据库连接数据库名;
配置需要生成表
ps:重要属性配置在 <table> 节点下
实体列用 false:驼峰 true:与数据表列相同-->
<property name="useActualColumnNames" value="false"/>
2、运行生成代码
右侧找到Maven——Plugins-找到对应mybatis-generator-右键 Run Maven Build 就可以生成相应代码了
3、实例代码下载：https://files.cnblogs.com/files/liyanbofly/mybaitsgenratecode.rar
下面进行介绍重点是 pom文件和mybatis-generator-config.xml 就可成功生成; 新建项目 配置pom和mybatis-generator-config.xml 及可Easy生成代码了。
