关于 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.

根据警告说明数据库驱动采用的是新的驱动器SPI机制加载的, 解决办法

1.驱动的全限定类名: 包名 + 类名, 改为com.mysql.cj.jdbc.Driver

spring.datasource.druid.driver-class-name=com.mysql.cj.jdbc.Driver

2.链接url的时区必须加上, 需要用到的地方都要加上

spring.datasource.druid.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true&serverTimezone=Asia/Shanghai
