java - 异常描述:[Entidades.Pais类]和[Entidades.Provincia类]之间遇到了不兼容的映射

这是具有其属性的Provincia类，我想与Pais类建立一个ManyToOne关系（一个Pais有很多Provincia）

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，类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;
}

可以帮助我的人。我正在使用NetBeans 7.3和EclipseLink..thanks

最佳答案

尝试如下更改

@JoinColumn(name="Pais_ID", referencedColumnName = "Id")
private Pais idPais;
