最近很多次遇到 The server time zone value 'Öйú±ê׼ʱ¼ä' is unrecognized or represents more than one time zone这个问题，

root cause

java.sql.SQLException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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.

网上的说

法也很多，经过测试，有效的一个办法如下：

mysql> show variables like '%time_zone%';
+------------------+--------+
| Variable_name    | Value  |
+------------------+--------+
| system_time_zone |        |
| time_zone        | SYSTEM |
+------------------+--------+
2 rows in set, 1 warning (0.00 sec)

mysql> set global time_zone = '+8:00';
Query OK, 0 rows affected (0.00 sec)

即可解决这个错误！

或者在数据库连接字符串是将时区设置好

JdbcUrl: jdbc:mysql://192.168.100.92:3306/bd?useSSL=false&serverTimezone=UTC #开发
