使用springboot最新版本mysql-Connector連接數據庫時報錯解決


在連接數據庫時,使用了最新版本的mysql-Connector,即6.0以上版本

1、報錯如下:

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

解決方法:

將 jdbc.driverClassName=com.mysql.jdbc.Driver 修改為

jdbc.driverClassName=com.mysql.cj.jdbc.Driver

 

2、報錯如下:

com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value 'Öйú±ê׼ʱ¼ä' 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.

解決方式:

在jdbc連接url中加入屬性serverTimezone,即需要指定時區。例如:

jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=gbk&useSSL=true

&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=Hongkong

serverTimezone只是擴展:

  1、選擇東8區的Hongkong、Asia/Shanghai或者Asia/Hongkong作為參數

  2、serverTimezone=GMT%2B8表示北京時間
