解决：Loading class `com.mysql.jdbc.Driver‘. This is deprecated

问题：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.

解决方式：

报错意思就是说com.mysql.jdbc.Driver这个驱动已经被弃用了，新的驱动为com.mysql.cj.jdbc.Driver，通常是自动注入的。

所以，我们只需要按照提示，将“com.mysql.jdbc.Driver”驱动改为“com.mysql.cj.jdbc.Driver”。

配置如下：

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: xxx
    password: xxx
    url: jdbc:mysql://localhost:3306/xxx?useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&useSSL=false&serverTimezone=Asia/Shanghai
