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.

2、时区问题

启动springboot项目,然后访问数据库,报You must configure either the server or JDBC driver (via the serverTimezone conf)的错误,原因

因为安装mysql的时候时区设置的不正确 mysql默认的是美国的时区,而我们中国大陆要比他们迟8小时,采用+8:00格式

 

使用的数据库是MySQL,从上面图看出SpringBoot2.3在你没有指定MySQL驱动版本的情况下它自动依赖的驱动是8.0.12很高的版本,这是由于数据库和系统时区差异所造成的,在jdbc连接的url后面加上serverTimezone=GMT即可解决问题,如果需要使用gmt+8时区,需要写成GMT%2B8,否则会被解析为空。再一个解决办法就是使用低版本的MySQL jdbc驱动,5.1.28不会存在时区的问题。

加上这个  ?serverTimezone=UTC 

spring.datasource.url=jdbc:mysql://localhost:3306/online_ssm?serverTimezone=UTC

spring.datasource.driver-class-name =com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/online_ssm?serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=qw123456
