Java OpenJPA：级联删除问题

我有以下实体：

//Parent
@Entity
@Table(name = "PARENT")
public class Parent  implements Serializable { 
private static final long serialVersionUID = 1L;

@Id
@Column(name = "PRIMARY_ID", updatable = false)
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer primaryID;

@OneToMany(mappedBy = "parent", cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER, targetEntity = Child.class)
private List<Child> child;

//Child

@Entity
@Table(name = "CHILD")
public class Child  implements Serializable {

private static final long serialVersionUID = 1L;

@EmbeddedId
private ChildPK id;

@MapsId("primaryID") //Maps to primaryID in ChildPK
@ManyToOne
@JoinColumn(name = "PRIMARY_ID",nullable=false)
private Parent parent;

public Child() {
}

我遇到以下异常。请查找以下堆栈跟踪：

---

目前，我通过在父对象之前对子对象调用移除操作来解决这个问题。我可以通过调用父记录上的删除操作来删除子记录。

如果设置

foreignkeydeletection=restrict

，我想这并不奇怪，是吗？您可能想尝试将其设置为

cascade

。@mustaccio我尝试设置foreignkeydeletection=cascade，JoinForeignKeyDeleteAction=cascade但仍然得到相同的问题如果我从子表中删除@MapsId注释并将persistence.xml中的属性保留为，则效果很好。但这样做，我的persistent操作失败，因为openjpa无法在子表中设置父主键值，我想如果设置
