java – 如何在hibernate中重复嵌入式

2023年5月5日 172次阅读

我有这个类,我试图在Hibernate 3.6.x中映射

@Entity @Table(name = "address") @Inheritance()
public abstract class Address {
    @Column(name = "address_type") @Enumerated(EnumType.STRING)
    private final AddressType addressType;

    @Embedded @AttributeOverrides({@AttributeOverride(name = "addressLine", column = @Column(name = "address_line1"))})
    private final AddressLine addressLine1;

    @Embedded @AttributeOverrides({@AttributeOverride(name = "addressLine", column = @Column(name = "address_line2"))})
    private final AddressLine addressLine2;

    @Embedded @AttributeOverrides({@AttributeOverride(name = "addressLine", column = @Column(name = "address_line3"))})
    private final AddressLine addressLine3;

    @Embedded @AttributeOverrides({@AttributeOverride(name = "addressLine", column = @Column(name = "address_line4"))})
    private final AddressLine addressLine4;

    @Embedded @AttributeOverrides({@AttributeOverride(name = "addressLine", column = @Column(name = "address_line5"))})
    private final AddressLine addressLine5;

    @Embedded @AttributeOverrides({@AttributeOverride(name = "postcode", column = @Column(name = "postcode"))})
    private final Postcode postcode;
}

我收到了这个错误. (我不完全理解 – 有人可以解释一下吗？)

Repeated column in mapping for entity:
Address column: addressLine (should
be mapped with insert=”false” update=”false”)

尽管@Embeddable AddressLine只是一个包装字符串的对象,但我希望保留该类型,以便稍后我可以添加行为/规则.

任何建议允许这种类型的配置？

最佳答案 我没有使用@AttributeOverride但我知道这个错误信息.它是由具有相同名称的列的多个映射引起的,在这种情况下,Hibernate忽略了您的列覆盖定义.

但是,就我而言,我使用的是@ManyToOne类,因此解决方案是@JoinColumns定义覆盖了原始列名.
