Connection failed. Verify all connection parameters and confirm that the appropriate driver is installed.
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.

解决办法
在连接属性,加上个参数即可:
serverTimezone = Hongkong
如下图所配置
