Do you have annotations in your Course entity? Because it is complaining about that as well in your exception

@Entity
public class Course {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private int id;

Also, don't forget a no-arg constructor.

I have made the changes but still that access denied error is coming.
Can you please update your stacktrace and share an image of your database as well? It is possible you either made a typo in your database name, or your mysql service is not working. Please update your question
I have updated the stacktrace and also added an image of database workbench
