You must configure either the server or JDBC driver (via the serverTimezone configuration property

使用JDBC连接MySql时出现：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

错误提示:
Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is 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.

解决办法;
在连接字符串后面加上?serverTimezone=UTC

其中UTC是统一标准世界时间。

完整的连接字符串示例：jdbc:mysql://localhost:3306/test?serverTimezone=UTC

或者还有另一种选择：jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8，这个是解决中文乱码输入问题，当然也可以和上面的一起结合：jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
