jdbc中的Driver报错

老师我的都导入了运行报错啊

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

java.sql.SQLException: The server time zone value '???ú±ê×??±??' 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.

同学你好，建议同学在url连接后加上如下代码再试试。如：

?characterEncoding=UTF8&serverTimezone=HongKong

修改后的url为：

jdbc:mysql://localhost:3306/hello?characterEncoding=UTF8&serverTimezone=HongKong

如果我的回答解决了你的疑惑，请采纳。祝：学习愉快~

老师还是报错Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary. java.sql.SQLException: No timezone mapping entry for 'HongKong'
