使用springboot配置本地数据库造成时差错误

java.sql.SQLException: The server time zone value '�й���׼ʱ��' is unrecognized or represents more than one time zone. 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. 

数据库配置spring.datasource.druid.url=jdbc:mysql://localhost:3306/ad


改为spring.datasource.druid.url=jdbc:mysql://localhost:3306/ad?serverTimezone=CTT&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true后问题解决
