java.sql.SQLException: The server time zone value '�й���׼ʱ��' is unrecognized..

mysql5.6.16使用jdbc连接时报错：

具体报错信息：
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.

即，url里设置一下时区就行了

原：

spring.datasource.url=jdbc:mysql://localhost:3306/demo

改：

spring.datasource.url=jdbc:mysql://localhost:3306/demo?
useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
