java.sql.SQLException: Unable to open a test connection to the given database. JDBC url = jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf8&useSSL=true&lazyInit=true, username = root.

Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------

java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

1.连接是用mysql没问题，2.mapper.xml 和mapper接口都是对应，3.jdbc配置也没问题，mapper.xml和mapper接口也配置对的
