java - DuplicateMappingException 由不同的逻辑列名表示

Question

我正在对两个类 MasavNew 和 MasavRow 使用 OneToMany 映射:

@Entity
@Table(name = "ArgoCHFileHdr")
public class MasavNew  {


@OneToMany(fetch = FetchType.LAZY, mappedBy = "msv",cascade = CascadeType.ALL)
@ElementCollection(targetClass=MasavRow.class)
private List<MasavRow> rows;

@Id
@Column(name = "[Arg.CH.F.Key]", nullable = false)
@GeneratedValue(strategy=GenerationType.IDENTITY)
protected Integer argCHFKey;

}


@Entity
@Table(name = "ArgoCHFileRow")
@DynamicUpdate
public class MasavRow extends IModel {


@ManyToOne(fetch = FetchType.LAZY,optional=true)
@JoinColumn(name="[Arg.CH.F.Key]")
private MasavNew msv;


@Id
@Column(name = "[Arg.CH.F.Key]", nullable = false)
private int argCHFKey;


@Id
@Column(name = "[Arg.CH.L.MNB]", nullable = false)
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer argCHLMNB;


@Column(name = "[Erp.Clnt]", nullable = true)
private String erpClnt;


}

然后在运行时我收到下一个异常:

我怎么能解决这个问题？

Answer 1

消除

@Id
@Column(name = "[Arg.CH.F.Key]", nullable = false)
private int argCHFKey;

因为您可以从 msv 对象中获取 key 。
