1、目的：我在开发环境中想引用相对路径的数据库驱动jar包，以便在部署环境不必修改数据库驱动的位置。(用maven管理jar包，而不用在开发环境一个配置，部署环境也有另一个配置)
2、问题：不知道怎么引用相对路径的jar包？
3、这是pom.xml中mybatis-generator-maven-plugin插件的配置
<plugin>
<!--
用maven mybatis插件
如果不在plugin里面添加依赖包得引用的话，会找不到相关得jar包，
在plugin外部得jar包，他不会去找到并执行，
所以要把plugin运行依赖得jar配置都放在里面

4、这是generatorConfig.xml

<!-- 类型转换 -->

</context>
</generatorConfiguration>
