java - 许多嵌入式属性引用相同的 Embeddable 类

Question

我想创建一个类 Exporter，它有两个电话号码:座机和手机。知道电话号码由国家代码和号码组成，我创建了一个 Embeddable 类:

@Embeddable
public class EmbeddablePhone implements Serializable {

    private static final long serialVersionUID = -6573789138766984739L;
    @Column(name = "COUNTRY_COD")
    private String countryCode;
    @Column(name = "PHONE_NUMBER")
    private String number;

    public EmbeddablePhone () {
    }

    //getters and setters 
}

如何在Exporter类中使用这个类来引用座机和手机:

public class Exporter implements Serializable{

.....
......

    @Embedded
    private EmbeddablePhone  landLine;
    @Embedded
    private EmbeddablePhone  moblePhone;
    public Exporter () {

    }

    //getters and setters

    }

Answer 1

使用 @AttributeOverride 注释。

@Embedded
@AttributeOverrides({
  @AttributeOverride(name="countryCode", column=@Column(name="MOB_COUNTRY_COD")),
  @AttributeOverride(name="number", column=@Column(name="MOB_NUMBER"))})
private EmbeddablePhone moblePhone;
