mysql的连接配置时区问题

mysql 5之前的配置：

driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&useSSL=false
username=****
password=****

------------------------------------

mysql 6之后的配置：
设置时区serverTimezone为UTC比北京时间早8个小时。

driverClassName=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/test?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&useSSL=false
username=****
password=****
-------------------------------------
设置时区为Asia/Shanghai为北京时间

driverClassName=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/test?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false 
username=****
password=****
