My App in SpringBoot can not run properly. Tried to change dependencies, classpath, deleting and reinstall whole folder with hibernate in local .m2. I'm making Spring boot security login system in my app, before that, everything was alright.

The problem is with how you have defined your entities. Both the superclass and the subclass have @Id attributes.
Inheritance should be governed by an IS-A HAS-A relationship.
Hence, the @Id in your subclass should be ruled out, because an instance of the subclass should be identifiable by the corresponding @Id of the superclass, which means the subclass must have the attribute that is supposed to be the @Id of the superclass (inheritance tree).
Furthermore, it is necessary that your superclass has an @Id, so quick solution is to get rid of the @Id in the subclass and add the same attribute in the subclass (without the @Id annotation).
/* Class level annotations */
public class Role { //Superclass
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "role_id")
private Integer roleId;
}
/* Class level annotations */
public class UserApp extends Role { //Subclass
private Integer roleId; // Same as the @Id in superclass
}
For further read-up on Inheritance in Hibernate, I suggest this article
