Answer 1

IOException:java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)
表明你数据库连接的用户名密码不对啊

Answer 2

这个好像是root用户没有权限在 'localhost' 上吧，把数据库中的root用户删除后重建再赋权限应该就行了。
楼主试试吧！

Answer 3

try
GRANT ALL PRIVILEGES ON *.* TO 'root@localhost'

Answer 4

IOException:java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)
你数据库服务没打开吧。
