Question

hibernate中注解manytoone使用复合主键怎样实现

Answer 1

你的KeyValuePK里面的内容，直接添加就可以！

public class BillTbodyPK implements Serializable {

private static final long serialVersionUID = -1190986010439330142L;

private SingleInfo mid;
private BillHeadModel billId;

public BillTbodyPK() {
}

// setter getter
@ManyToOne(fetch = FetchType.LAZY,cascade = { CascadeType.ALL })
@JoinColumn(name = "mid", referencedColumnName = "mid", unique = false, nullable = false, insertable = false, updatable = false)
@NotFound(action = NotFoundAction.IGNORE)
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
public SingleInfo getMid() {
return mid;
}

public void setMid(SingleInfo mid) {
this.mid = mid;
}

@ManyToOne
@JoinColumn(name = "dj_id", nullable = false)
@NotFound(action = NotFoundAction.IGNORE)
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
public BillHeadModel getBillId() {
return billId;
}
