需要查看pom.xml db.properties
尝试做如下修改：
1、版本问题，尝试修改版本 8.0.15
mysql
mysql-connector-java
8.0.15
2、更改db.properties
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mydb?rewriteBatchedStatements=true&useUnicode=true&characterEncoding=utf8&serverTimezone=UTC&useSSL=false
jdbc.username=root
jdbc.password=123456
备注：记得路径问题
