Hibernate Cascade:保存父实体而不保存子实体时删除子实体

所以我有一个schedule对象,它包含DateActiveScheduleItems的列表。我希望这样,如果我从schedule对象的列表中删除DateActiveScheduleItems项目,并使用CrudeRepository保存该计划,它会从数据库中删除DateActiveScheduleItem,但目前我的代码似乎没有这样做。我应该如何改变级联?

@Entity
public class Schedule {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@ManyToOne
@JoinColumn(name = "user_id")
private User user;

@ManyToOne
@JoinColumn(name = "usergroup_id")
private UserGroup userGroup;

private String description;


private boolean master;//is this a schedule for all supervalus(true) or one supervalu(false)

@OneToMany(mappedBy = "schedule",cascade = CascadeType.ALL)
private List<DateActiveScheduleItem> dateActiveScheduleItems = new ArrayList<>();

@OneToMany(mappedBy = "schedule",cascade = CascadeType.PERSIST)
private List<MusicScheduleItem> musicScheduleItems = new ArrayList<>();

@OneToMany(mappedBy = "schedule",cascade = CascadeType.PERSIST)
private List<AdvertisementScheduleItem> advertisementScheduleItems = new ArrayList<>();

@Basic
@Temporal(TemporalType.DATE)
private java.util.Date dateAdded;
public Long getId() {
    return id;
 //getters setters
}

DateActiveScheduleItem

@Entity
public class DateActiveScheduleItem {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

@Basic
@Temporal(TemporalType.DATE)
private Date date;



@JsonIgnore
@ManyToOne
@JoinColumn(name = "schedule_id")
private Schedule schedule;
//getters setters}
