Yes, hibernate have prebuilt String generators. Just substitute your @GenericGenerator definition to another strategy.

@Entity
@Table(name = "contact")
public class Contact implements Serializable, Identifiable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(generator = "uuid")
    @GenericGenerator(name = "uuid", strategy = "uuid2")
    private String id;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }
}

For more information about different hibernate generators you can look at documentation.
