准备使用mybatis-plus + Hikari + SpringBoot 搭建一个项目，结果一直报错Could not create connection to database server
报错信息如下：

从错误信息的提示看到：
You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
可能存在两个问题，一是数据库驱动的问题，而是数据库时区错误；
解决方法：
1、我在yml文件配置驱动包的时候引入了错误的包，如下：错误示例：
spring:
# DataSource Config 使用 HikariCP 数据源
datasource:
driver-class-name: com.mysql.jdbc.Driver
正解：
spring:
# DataSource Config 使用 HikariCP 数据源
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
2、时区识别乱码问题
这里贴出我修改成功的url
jdbc:mysql://localhost:3306/test?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&autoReconnect=true
