I am using Hibernate for loading data from db. I have entity which looks like this:

@Data
@Entity
@NoArgsConstructor
public class Role 
 @Id@GeneratedValue@Column(name = "ID_ROLA")
 private int idRole;
 @Basic@Column(name = "NAZWA")
 private String name;
 @Basic@Column(name = "UPRAWNIENIA")
 private Integer permits;

And class RoleDAOImpl which have method like add(),search() or getListofRoles().

Now i want to bind that Entity class to TableView to show all of my Roles (I have all roles in my List< Role > roles).

How can I add this to TableView?
I know that TableView should be bind to XProperties for example StringProperty.
But i don't want to do StringProperty in my Entity class, because I think it can ruin my database structure or something.

I would like to have separate class for properties.
I thought about creating RoleTableModel class which will contain Properties for Role class and then bind RoleTableModel class to TableView.

Is it possible? How to do this thing?

  Use PropertyValueFactory. Do note that your TableView would not respond to any changes to existing Role objects (you need to remove and re-add them).

  what exactly is the problem? all your entity needs are getters and setters - then propertyValueFactory will do both reading and writing to the entity.

  so when I want to create a column which will show field from entity for example idRole, I have to write only this? idCol.setCellValueFactory(new PropertyValueFactory<>("idRole"));

  what happened when you tried it :) yeah, that should work. If not, please provide a minimal reproducible example that demonstrates the problem.
