springboot+maven+mybatis 多模块项目中使用maven的generator生成器

其实很简单

想看目录结构

blog-dao就是我的数据库连接层.

1 引入mybatis-generator-maven-plugin

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.2</version>
    <configuration>                                
        <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
        <verbose>true</verbose>
        <overwrite>true</overwrite>
    </configuration>
</plugin>

2  generator.xml

<?xml version="1.0" encoding="UTF-8"?>

        <commentGenerator>

</generatorConfiguration>

只需要这两个步骤就搞定了,当然你的实体 mapper xml这几个包最好都在数据库连接层这个module里面,generator.xml里面的配置都有备注,里面没有备注的一些属性请自行百度.

 然后再点一下这个就好了,
