IDEA--Could not create connection to database server

阿新 • • 發佈：2020-10-20

在springboot專案執行時，出現Could not create connection to database server報錯；
原因：mysql版本號和maven中pom檔案中配置的mysql-connector版本號不同。
解決方案：將pom檔案中的版本號改成本地mysql的版本號以後再更新maven
步驟：
1、在win+r中連線MySQL，輸入select version() from dual;查詢出自己的MySQL版本；
2、在pom.xml中加入 8.0.17（我的MySQL版本是8.0.17）並同步在這裡插入圖片描述

3、檢測MySQL驅動名，改為driver-class-name: com.mysql.cj.jdbc.Driver
