环境说明:Windows10、JDK8、ojdbc6-11.2.0.4.jar、mybatis-generator-core-1.3.7.jar

1、在C盘新建autoMybatis文件夹,文件夹中新建generator.xml文件,并将ojdbc6-11.2.0.4.jar 和mybatis-generator-core-1.3.7.jar拷贝至当前文件夹中:

整体截图:

配置文件如下:

	</context> 
</generatorConfiguration>

2、打开CMD命令行,切换到autoMybatis路径下,执行以下命令:

java -jar mybatis-generator-core-1.3.7.jar -configfile generator.xml -overwrite

3、提示错误信息:无法加载Oracle的驱动,

截图待补充:

解决办法:在 generatorConfig.xml 文件中配置<classPathEntry> 元素
