大佬可以回忆一下这个项目jdbc的版本吗，检查了好几遍数据库还是连接不上，怀疑是驱动问题。

你的数据库版本过高了吧，需要修改mysql-connector-java 的版本

我的mysql是5.7但是也是出错了，后来我这样改好像就没问题了
改pom

mysql
mysql-connector-java
8.0.26

改驱动和jdbc的url

jdbc.driverClassName=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/bookstore?serverTimezone=UTC&characterEncoding=utf-8&useSSL=false&allowPublicKeyRetrieval=true
