刚学jdbc遇到的问题
Exception in thread "main" 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.
错误为系统时间错误
只需要在访问数据库的Url后面加上以下的语句即可:
?serverTimezone=GMT%2B8
或者
&serverTimezone=UTC
例如URL为:
jdbc:mysql://localhost:host/data01
改为
jdbc:mysql://localhost:host/data01?serverTimezone=GMT%2B8
加过之后运行成功输出结果但出现了这个问题
** BEGIN NESTED EXCEPTION **

解决办法就是在URL的后面加上&useSSL=false
jdbc:mysql://localhost:host/data01?serverTimezone=GMT%2B8&useSSL=false
