Introduced mysql driver:
SpringBoot integration framework Mybatis, the time of the visit Controller:
ava.sql.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.

Queries to the solution as follows :( guess estimate is because jdbc driver SpringBoot 2.1.x version used is more than 6.0 bar)
The reason is because of the use Mysql Connector / J version 6.x or more, and then they reported the wrong time zone
Problems encountered: servertime = UTC resulting in eight hours time difference
MySQL jdbc 6.0 or later must configure this parameter
Solution:
Can not simply be written when configuring the url: jdbc: mysql: // localhost: 3306 / mysql
We must write: jdbc: mysql: // localhost: 3306 / mysql serverTimezone = UTC?

While the above plus the area of the program is not wrong, but we have a problem in inserting java code into the database when the time.
For example, in java code inserted inside time: 2017-08-21 17:29:56
But in time it is displayed inside the database: 2017-08-21 09:29:56
Because of time zone issues.
On behalf of UTC is a global standard time, but the time we are using the Beijing time zone is east eight districts, leading UTC eight hours.
UTC + (+0800) = local (Beijing) time
