5.检查数据库是否正在运行，并确保可以从应用程序服务器访问它。

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

This error message indicates that the user "root" is being denied access to the database server at "localhost" because the provided password is incorrect.

There are a few possible reasons why this might be happening:

1. The password for the "root" user has been changed or forgotten.
2. The "root" user has not been granted proper privileges to access the database server.
3. There is a typo or error in the connection string that is being used to connect to the database server.

To resolve this issue, you should verify the following:

1. Make sure that the password being used to connect to the database server is correct. If you have forgotten the password, you may need to reset it.
2. Check that the "root" user has the necessary privileges to access the database server. You can do this by logging into the database server with another user account that has administrative privileges and granting the necessary permissions to the "root" user.
3. Verify that the connection string being used to connect to the database server is correct, and that there are no typos or errors.
