背景

今天專案切換到了mysql8.0.12，結果還多了一個報錯，看來8和5.7的差別還真大。。。煩煩煩。。。

com.mysql.cj.exceptions.InvalidConnectionAttributeException: 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.

就是說mysql的伺服器時區無法識別或存在/代表多個時區。您必須在JDBC的URL指定serverTimezone=UTC來解決這個問題=。=

Solution

於是我的jdbc url就變得無比的長。。。解決以上問題需要加多一個&serverTimezone=UTC

url: jdbc:mysql://localhost:3306/mcms?autoReconnect=true&useUnicode=true&characterEncoding=utf8&useSSL=false&allowMultiQueries=true&serverTimezone=UTC
