New version of database driver connection exception

java.sql.SQLException: The server time zone value 'EDT' 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.

The database used is MySQL and the driver is 8.0.16. This is due to the new version of the database driver connector needs to specify UTC time zone caused by the jdbc connection url after the serverTimezone=GMT can solve the problem, if you need to use gmt+8 time zone, need to write GMT%2B8, otherwise it will be resolved to null. Another solution is to use a lower version of MySQL jdbc driver, 5.1.28 does not have time zone problems.
