使用JDBC连接MySql时出现
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.
将com.mysql.jdbc.Driver改为com.mysql.cj.jdbc.Driver
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.
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*
