SpringBoot 2.1.4启动时报错

java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time......

application.properties中数据库配置为:

spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=youotech
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
解决方案1
在mysql中执行命令: 
set global time_zone='+8:00' 
解决方案2
修改application.properties数据库配置,添加serverTimezone=UTC:
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
