JPA secodaryTables with composite key

Question

I'm working on a legacy database schema. On this schema there are 2 tables: clienti 1->many clienti_soc

clienti has the primary key id_cliente, clienti_soc has composite key (id_cliente, id_societa). In my JPA application I need to pick the record of clienti_soc with a specific value of id_societa I'd like to put in my application.properties.

Here how I mapped my entity

@Entity
@Table(name="va_clienti")
@SecondaryTable(name = "va_clienti_soc", pkJoinColumns = @PrimaryKeyJoinColumn(name = "id_cliente"))
@Data
public class Cliente {
    @Id
    public String idCliente;
    public String ragioneSociale;   
    ....
    
    @Column(table = "va_clienti_soc" , name="id_societa")
    public String idSocieta = "1";    // <-- ????????
    @Column(table = "va_clienti_soc" , name="id_gr_prezzi_partner")
    public String idGrPrezziPartner;    

}

is there a better way or any best practice to crerate the JPA enity? Is there a cleverer use of @PrimaryKeyJoinColumn annotation?
