Question

我正在尝试运行此基本代码。模型1。

public class CustomEntity implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Long id;

@JsonManagedReference
@OneToMany(mappedBy = "customEntity", fetch = FetchType.LAZY, cascade = { CascadeType.ALL }, orphanRemoval = true)
Set<CustomEntitySystem> customEntitySys;

位于CustomEntity下的模型2。

public class CustomEntitySystem implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Long id;

@ManyToOne
@JsonBackReference
@JoinColumn(name = "CUSTOM_ENTITY_ID")
private CustomEntity customEntity;

@JsonManagedReference
@OneToMany(mappedBy = "customEntitySystem", fetch = FetchType.LAZY, cascade = { CascadeType.ALL }, orphanRemoval = true)
private Set<CustomEntityRole> customEntityRole;

}

现在我们在CustomEntitySystem下拥有第三个模型

public class CustomEntityRole implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private Long id;

@ManyToOne
@JoinColumn(name = "CUSTOM_ENTITY_SYS_ID")
@JsonBackReference
private CustomEntitySystem customEntitySystem;

@Column(name = "CUSTOM_ENTITY_ID")
private CustomEntity customEntity;

}

当我尝试使用存储库保存完整的CustomEntity对象时

customEntityRepository.save（customEntity）;

然后我面临以下错误。

由于：org.hibernate.PersistentObjectException：分离的实体传递给坚持：com.rbac.model.CustomEntityRole在 org.hibernate.event.internal.DefaultPersistEventListener.onPersist（DefaultPersistEventListener.java:124）在 org.hibernate.internal.SessionImpl.firePersist（SessionImpl.java:806）在org.hibernate.internal.SessionImpl.persist（SessionImpl.java:773）在 org.hibernate.jpa.event.internal.core.JpaPersistEventListener $ 1.cascade（JpaPersistEventListener.java:80）在 org.hibernate.engine.internal.Cascade.cascadeToOne（Cascade.java:467）在 org.hibernate.engine.internal.Cascade.cascadeAssociation（Cascade.java:392）在 org.hibernate.engine.internal.Cascade.cascadeProperty（Cascade.java:193）在 org.hibernate.engine.internal.Cascade.cascadeCollectionElements（Cascade.java:500）在 org.hibernate.engine.internal.Cascade.cascadeCollection（Cascade.java:432）在 org.hibernate.engine.internal.Cascade.cascadeAssociation（Cascade.java:395）在 org.hibernate.engine.internal.Cascade.cascadeProperty（Cascade.java:193）在org.hibernate.engine.internal.Cascade.cascade（Cascade.java:126）

请解释我错了预先感谢。

传递的分离实体与ManyToOne col保持一致
