休眠两次映射同一列并插入

阿伦MR Nair

我想插入包含从同一表（组织表）引用的两个文件名organization_id和account_id的行。

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;

但我得到以下错误。

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

当我添加insert="false" update="false"帐户时，错误消失了。但是我需要同时插入帐户和组织。

为EntityModel添加一个主键。

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;

}
