该项目用于快速生成vo、model、mapper、mapping
github地址：https://github.com/caojx-git/mybatis-generator-demo
该代码位于test/java目录下，StartUp是生成代码的入口
generatorConfig.xml 用 model、mapper、mapping的生成，代码生成路径可自行配置
generatorConfig-vo.xml 用于vo的生成，代码生成路径可自行配置

}将author改成自己的名称，不配置使用默认，注意使用mybatis-plus中实体标注的主键生成策略注解使用 @TableId(value = "id", type = IdType.AUTO) 需要自行修改见https://mp.baomidou.com/guide/annotation.html#tableid

注意：mybatis-plus中自定义了主键生成策略，见https://mp.baomidou.com/guide/annotation.html#tableid
