Mysql - com.mysql.jdbc.Driver与com.mysql.cj.jdbc.Driver的区别

spring:
  datasource:
    username: root
    password: root
    url: jdbc:mysql://localhost:3306/datamiddle?characterEncoding=utf8&useSSL=true&rewriteBatchedStatements=true
    driver-class-name: com.mysql.jdbc.Driver # 或 `com.mysql.cj.jdbc.Driver

public class Driver extends com.mysql.cj.jdbc.Driver {
    public Driver() throws SQLException {
    }

    static {
        System.err.println("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.");
    }
}
