IntelliJ IDEA

创建工程并配置了各种环境后启动项目出现错误：

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.

 

解决方法：

将 application.properties文件下的

spring.datasource.driver-class-name: com.mysql.jdbc.Driver

修改成

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