mybaits 学习3-多个数据源

数据源添加mysql和oracle
代码见具体github：https://github.com/JNUpython/springboot2/tree/develop

ojdbc依赖无法下载

github上面下载该jar 并通过maven命令本地安装

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc7 -Dversion=12.1.0.2 -Dpackaging=jar -Dfile=./libs/ojdbc7-12.1.0.2.jar 

mybatis 全局配置xml文件，以及数据库配置文件
