#4.mybatis.cfg.xml配置

附件db.properties

sqlserverDriver=com.microsoft.sqlserver.jdbc.SQLServerDriver

sqlserverUrl=jdbc\:sqlserver\://127.0.0.1\:1433;DatabaseName=ShareZone

sqlserverUsername=sa

sqlserverPassword=123456

 

mysqlDriver=com.mysql.jdbc.Driver

mysqlUrl=jdbc:mysql://localhost:3306/ShareZone

mysqlUsername=root

mysqlPassword=root

这样基本整合就结束了！
