Hibernate 两次映射同一列并插入

Question

我想插入一个包含两个文件名 organization_id 和 account_id 的行，它们是从同一个 table（组织 table）引用的。

EntityModel.java

@ManyToOne
@JoinColumn(name = "organization_id")
private OrganizationModel organization;

@ManyToOne
@JoinColumn(name = "account_id")
private OrganizationModel account;

OrganizationModel.java

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "organization_id", unique = true, nullable = false)
private int organizationId;

@OneToMany(mappedBy = "organization")
private Set<EntityModel> organization;

但是我收到以下错误。

Repeated column in mapping for entity: com.party.OrganizationModel column: organization_id (should be mapped with insert="false" update="false")

当我为帐户添加 insert="false" update="false" 时，错误 gone.But 我需要同时插入帐户和组织。

Answer 1

为 EntityModel 添加主键。

这是对我有用的代码：

@Entity
@Table(name = "EntityModel")
public class EntityModel {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "entity_model_id", unique = true, nullable = false)
    private int entityModelId;

    @ManyToOne
    @JoinColumn(name = "organization_id")
    private OrganizationModel organization;

    @ManyToOne
    @JoinColumn(name = "account_id")
    private OrganizationModel account;

}

@Entity
@Table(name = "OrganizationModel")
public class OrganizationModel {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "organization_id", unique = true, nullable = false)
    private int organizationId;

    @OneToMany(mappedBy = "organization")
    private Set<EntityModel> organization;

}
