連接mysql數(shù)據(jù)庫時發(fā)生的錯誤：

Connection to oto@localhost failed.
[08001] Could not create connection to database server. Attempted reconnect 3 times. Giving up.

或許是因為數(shù)據(jù)庫版本的原因，最后加上如下語句即可。

?serverTimezone=UTC

注：jdbc.url=jdbc:mysql://localhost:3306/oto?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
