例外描述：[class Entidades.Pais]和[class Entidades.Provincia]之间遇到不兼容的映射

Question

这是具有属性的Provincia类，我想与Pais类（一个Pais有很多Provincia）建立关系ManyToOne

public class Provincia implements Serializable {
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "idProvincia")
    private Collection<Localidad> localidadCollection;
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @Column(name = "Id")
    private Long id;
    @Basic(optional = false)
    @Column(name = "Nombre")
    private String nombre;
    @NotNull
    @Basic(optional = false)
    @ManyToOne
    @JoinColumn(name="Pais_ID", referencedColumnName = "Pais_ID")
    private Pais idPais;
}

现在是班级Pais及其属性

public class Pais implements Serializable {
    private static final long serialVersionUID = 1L;
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "idPais")
    private Collection<Provincia> provinciaCollection;
    @Id
    @Basic(optional = false)
    @Column(name = "Id")
    private Long id;
    @Basic(optional = false)
    @Column(name = "Nombre")
    private String nombre;
}

private Pais idPais;
