@ManyToMany 未加载

有三张桌子。第一个带有日期的日历。

@Entity
@NamedEntityGraph(
        name = "eventCalendar.events",
        attributeNodes = @NamedAttributeNode("events"),
        subgraphs = {
                @NamedSubgraph(
                name = "event-with-contacts-and-eventContents",
                type = Event.class,
                attributeNodes = { @NamedAttributeNode("contacts"),
                                    @NamedAttributeNode("eventContents") })})
public class EventCalendar extends BaseEntity {
    private Long day;
    @Column(columnDefinition = "boolean default false")
    private Boolean isActive;
    @OneToMany(mappedBy = "eventCalendar",cascade = CascadeType.ALL)
    private List<Event> events = new ArrayList<>();
}

每个日期可以有多个事件。

@Entity
@NamedEntityGraph(name = "event-with-contacts-and-eventContents",
        attributeNodes = { @NamedAttributeNode("contacts"), @NamedAttributeNode("eventContents") })
public class Event extends BaseEntity {
    @OneToMany(mappedBy = "event",cascade = CascadeType.ALL)
    private List<EventContent> eventContents = new ArrayList<>();
    @ManyToOne
    @JoinColumn(name = "event_calendar_id")
    private EventCalendar eventCalendar;
    @ManyToMany
    private Set<Contact> contacts = new LinkedHashSet<>();
}

每个事件可以有很多参与者，就像一个参与者可以在许多事件的列表中一样

@Entity
public class Contact extends BaseEntity {
    private String surname;
    private String name;
    private String patronymic;
    @ManyToMany
    private Set<Event> events = new LinkedHashSet<>();
}

日历存储库

@Repository
public interface EventCalendarRepository extends BaseRepository<EventCalendar> {
    @EntityGraph(value = "eventCalendar.events", type = EntityGraph.EntityGraphType.LOAD)
    List<EventCalendar> findByDayIn(Long[] days);
}

eventContents 字段已加载，但未加载联系人。怎么修？
