1、使用MySQL8.0.11版本，要使用5.1.45或其他高版本驱动jar包，我本地使用的是最新的8.0.11
2、更换了MySQL驱动后，报Cannot find class [com.alibaba.druid.pool.DruidDataSource] for bean ················类似错误
然后就更新druid包到1.1.10版本，此处要查看maven上druid包1.1.10版对应的MySQL驱动包版本、MyBatis版本、及Spring版本

3、此时可以正常操作数据库了，但是后台会有提示信息：
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
那么就把MySQL驱动类换成com.mysql.cj.jdbc.Driver即可
