里面指定了配置文件路径：
<configurationFile>src/main/java/club/kittybunny/mybatistool/generatorConfig.xml</configurationFile>
三、创建配置文件
在指定路径下创建配置文件generatorConfig.xml

以下内容自行修改：
里面2个表的配置：一个默认、一个指定个别字段的转换类型和主键自动生成（插入数据后内存中对象获得主键）。
指明了驱动路径是：
"/home/bunny/文档/mysql-connector-java-5.1.25-bin.jar"
连接信息：
jdbcConnection
生成文件的包路径和文件位置：
javaModelGenerator
sqlMapGenerator
javaClientGenerator
四、运行程序生成代码
找到相应的jar运行，在配置好的路径下就会出现生成的文件，不可以重复生成。如果要再次生成，需要把原有路径下生成内容删除。
