解決：Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone valu

//報(bào)錯(cuò)信息

Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value ‘?D1ú±ê×?ê±??‘ 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.

此問題為時(shí)區(qū)問題,在 JDBC 的連接 url 部分加上 serverTimezone=UTC 即可。

如圖：

解決：Loading class `com.mysql.jdbc.Driver‘. This is deprecated. The new driver class is `com.mysql.cj.jdb

措施：現(xiàn)在按照最新官方提示支持將com.mysql.jdbc.Driver ?改為? com.mysql.cj.jdbc.Driver

提示：并不是修改maven中對于數(shù)據(jù)庫加載驅(qū)動(dòng)的以來名稱

driver = "com.mysql.jdbc.Driver";//更改為

driver = "com.mysql.cj.jdbc.Driver";//報(bào)錯(cuò)即可消失
