Spring Data JPA：删除父实体，不会删除子实体

Question

我的实体。ValidationStep与documentDetail有一对一的关系，documentDetail与documentValidations有一个完全的关系

@Entity
public class ValidationStep {

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

@ManyToOne
@JoinColumn(name= "automation_information_aId", referencedColumnName= "aId")
private AutomationInformation automationInformation;

@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
@OneToOne(cascade = { CascadeType.ALL }, orphanRemoval = true,fetch=FetchType.LAZY)
private DocumentDetail documentDetail;
 }

@Entity
public class DocumentDetail {

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

@OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
@JoinColumn(name = "documentDetail_id")
private List<DocumentValidation> documentValidationList

@Entity
public class DocumentValidation implements Comparable {

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


}

我的删除查询

        @Modifying
    @Query(value = "DELETE FROM ValidationStep validationStep WHERE validationStep.automationInformation.id = :aId AND isDraft is true")
    void  deleteAllDraftsByAutomationInformationaID(@Param("aId") Long aId);

父ValidationStep被删除，但是docDetail和documentValidations仍然在数据库中。

来自JPA规范（第4.10段：批量更新和删除操作）：

删除操作仅适用于指定类及其子类的实体。它不级联到相关实体。

只有在执行useentitymanager.remove()删除实体时，删除级联才起作用。如果执行删除查询，则不会。
