Error setting driver on UnpooledDataSource. Cause: java.lang.ClassNotFoundException: Cannot find cla

Maven中使用MyBatis框架报如下错误：

MySQL 8.0.19

JDK 1.8

Maven 3.6.3

在这里插入代码片org.apache.ibatis.exceptions.PersistenceException: 
### Error querying database.  Cause: java.sql.SQLException: Error setting driver on UnpooledDataSource. Cause: java.lang.ClassNotFoundException: Cannot find class: com.mysql.cj.jdbc.Driver
### The error may exist in com/itcode/dao/Mapper.xml
### The error may involve com.itcode.dao.UserMapper.selectById
### The error occurred while executing a query
### Cause: java.sql.SQLException: Error setting driver on UnpooledDataSource. Cause: java.lang.ClassNotFoundException: Cannot find class: com.mysql.cj.jdbc.Driver

**上述问题是因为无法读取到数据库驱动 **

解决方案

1. 要确保Maven工程成功导入数据库连接的依赖
   

2. 确保主配置文件数据库的连接配置无误
   

3. 如果1、2都确保无误再看第三条吧！

   我是这样粗暴导入的~
   哪个小可爱有别的更优方案，踢我以下！！！
