解决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 specific time zone value if you want to utilize time zone support.问题
报错信息：
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 specific time zone value if you want to utilize time zone support.
服务器时区值'�й���ʱ��' 无法识别或表示多个时区。如果要利用时区支持，必须将服务器或JDBC驱动程序(通过“serverTimezone”配置属性)配置为使用更具体的时区值。
解决方式：
在URL上添加serverTimezone=UTC
String url = "jdbc:mysql://localhost:3306/school?serverTimezone=UTC"；
或
//在Mybatis中
jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT
