我得买些模型，例如付款单和运单。一个付费侦察员身上可以有一套运单。但我不想把运单和它紧紧地联系在一起。所以我创建了如下模型：
付款侦察

@SuppressWarnings("serial")
@Entity
public class PaymentReconciliation extends BaseEntity {
@Column
private String parentId;
@Column
private BigDecimal grossAmount;
@Column
private String currency;
@Column
private Integer totalNumberOfPackages;
@Column
@ManyToMany(fetch = FetchType.LAZY)
@JoinTable(name = "PayReconWaybillMap", joinColumns = { 
@JoinColumn(name = "reconId") }, inverseJoinColumns = {
        @JoinColumn(name = "waybillId") })
private Set<WayBill> waybill = new HashSet<WayBill>();
}

瓦比尔

@SuppressWarnings("serial")
 @Entity
 public class PaymentReconciliation extends BaseEntity {
 @Column(nullable = false, unique = true)
 private String barCode;
  @Column
  private String consigneeName;
  @Column
  @JsonIgnore
  private String countryCode;

 }

现在，我有三张table。所以在发展之后事情就结束了。我要拿不附在任何付款通知上的运单。谁能帮我弄到这个吗。
