我的域类如下：
1-音频文件参考：
@SuppressWarnings("serial")
@Entity
@Table(name = "audiofileref", catalog = "advertisedb")
public class Audiofileref implements java.io.Serializable {
@OneToMany(fetch = FetchType.LAZY, mappedBy = "audiofileref", cascade = CascadeType.ALL)
private Set<Adpage> adpages = new HashSet<Adpage>(0);
}
2- 广告页：
@SuppressWarnings("serial")
@Entity
@Table(name = "adpage", catalog = "advertisedb")
public class Adpage implements java.io.Serializable {
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "audio_file_id", unique = true, nullable = true)
private Audiofileref audiofileref;
@OneToMany(fetch = FetchType.LAZY, mappedBy = "adpage", cascade = CascadeType.ALL)
private Set<ImageFileRef> imageFileRefs = new HashSet<ImageFileRef>(0);
@OneToMany(fetch = FetchType.LAZY, mappedBy = "adpage", cascade = CascadeType.ALL)
private Set<PageActionPlanMap> pageActionPlanMaps = new HashSet<PageActionPlanMap>(
0);
}
3- ImageFileRef：
@SuppressWarnings("serial")
@Entity
@Table(name = "imagefileref", catalog = "advertisedb")
public class ImageFileRef implements java.io.Serializable {
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "fk_adpage", nullable = false)
private Adpage adpage;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "PhTypeID")
private Phonescreentype phonescreentype;
}
4- PageActionPlanMap：
@SuppressWarnings("serial")
@Entity
@Table(name = "pageactionplan_map", catalog = "advertisedb")
public class PageActionPlanMap implements java.io.Serializable {
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "fk_adpage", nullable = false)
private Adpage adpage;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "APID", nullable = false)
private Actionsplan actionsplan;
}
5- 行动计划：
@SuppressWarnings("serial")
@Entity
@Table(name = "actionsplan", catalog = "advertisedb")
public class Actionsplan implements java.io.Serializable {
@OneToMany(fetch = FetchType.LAZY, mappedBy = "actionsplan")
private Set<PageActionPlanMap> pageActionPlanMaps = new HashSet<PageActionPlanMap>(
0);
}
要求：
- 删除Audiofileref时， Adpage中的外键设置为 null；
- 删除Adpage时，将删除以下内容：Audiofileref、ImageFileRef、PageActionPlanMap
删除 Audiofileref 时我得到了什么：
Hibernate: select adpages0_.audio_file_id as audio7_3_1_, adpages0_.pkid as pkid1_, adpages0_.pkid as pkid1_0_, adpages0_.fk_advertisement as fk6_1_0_, adpages0_.audio_file_id as audio7_1_0_, adpages0_.Description as Descript2_1_0_, adpages0_.HomePage as HomePage1_0_, adpages0_.Name as Name1_0_, adpages0_.Text as Text1_0_ from advertisedb.adpage adpages0_ where adpages0_.audio_file_id=?

Hibernate: delete from advertisedb.pageactionplan_map where pkid=?
Hibernate: delete from advertisedb.pageactionplan_map where pkid=?
Hibernate: delete from advertisedb.adpage where pkid=?
Hibernate: delete from advertisedb.audiofileref where pkid=?
然后我得到以下异常，并且 Audiofileref 没有被删除：
