我有以下类Interval,带有3个外键的复合主键,一个用于实体Event,另外两个用于Entity EventPackage。我一直试图解决错误没有成功。
@Entity
@IdClass(IntervalPK.class)
@Table(name = "intervals")
public class Interval implements Serializable {
// VARIABLES
private static final long serialVersionUID = 1L;
@Id
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "event_id", nullable = false)
public Event event;
@Id
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "start", referencedColumnName= "eventpackage_id", nullable = false)
public EventPackage start;
@Id
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "end", referencedColumnName= "eventpackage_id", nullable = false)
public EventPackage end;
@Column(name = "state", nullable = false)
public int state;
...
}
这是与EventPackage相关的类事件,并且可以正常工作。
public class Event {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name = "event_id")
private int eventid;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "eventpackageid", nullable = true)
private EventPackage eventpackage;
@OneToMany(fetch = FetchType.LAZY, mappedBy = "event")
private Set<Interval> intervals;
...
}
这是de class EventPackage
@Entity
@Table(name = "eventpackage")
public class EventPackage {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name = "eventpackage_id")
private int eventpackageid;
@OneToMany(fetch = FetchType.LAZY, mappedBy = "eventpackage", cascade = CascadeType.ALL, orphanRemoval = true)
private Set<Event> events;
@OneToMany(fetch = FetchType.LAZY, mappedBy = "start", cascade = CascadeType.ALL, orphanRemoval = true)
private Set<Interval> start;
@OneToMany(fetch = FetchType.LAZY, mappedBy = "end", cascade = CascadeType.ALL, orphanRemoval = true)
private Set<Interval> end;
...
}
这是主键Interval类:
@Entity
@IdClass(IntervalPK.class)
@Table(name = "intervals")
public class Interval implements Serializable {
// VARIABLES
private static final long serialVersionUID = 1L;
@Id
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "event_id", nullable = false)
public Event event;
@Id
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "start", referencedColumnName= "eventpackage_id", nullable = false)
public EventPackage start;
@Id
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "end", referencedColumnName= "eventpackage_id", nullable = false)
public EventPackage end;
我也在使用JPA存储库:
/** Interval Repository */
public interface IntervalRepo extends CrudRepository<Interval,IntervalPK>, IntervalRepoCustom {
}
最后是错误,我认为JPA Data存储库存在一些问题:
org.springframework.orm.jpa.JpaObjectRetrievalFailureException: Unable to find es.citic.cms.model.acq.Interval with id es.citic.cms.model.acq.IntervalPK@3; nested exception is javax.persistence.EntityNotFoundException: Unable to find es.citic.cms.model.acq.Interval with id es.citic.cms.model.acq.IntervalPK@3
