一、问题

Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: 
Failed to obtain JDBC Connection; nested exception is java.sql.SQLException:

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.
