spring-data-jpa transient 示例必须在当前操作之前保存，但该示例根本不是 transient 示例

标题中的错误声称示例是短暂的，但它绝对不是：它只是从数据库中提取并用作引用。我不明白该错误。
在一个Sping Boot with JPA应用程序中，我有一个聚合的RosterPeriod，它包含一个RosterDates列表，每个RosterDates包含一个Shifts列表，所有的都进行级联。
名册期：

@OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "rosterPeriod", fetch = FetchType.EAGER)
private final Set<RosterDate> rosterDates = new HashSet<>();

名册日期：

@OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "rosterDate", fetch = FetchType.EAGER)
private final Set<Shift> shifts = new HashSet<>();

@ManyToOne
@NotNull
RosterDate rosterDate;

Shift有一个ShiftType，它不是聚合的一部分，而只是一个引用。
班次：

@ManyToOne
@NotNull
private ShiftType shiftType;

@ManyToOne
@NotNull
RosterDate rosterDate;

当创建新的RosterPeriod时，也会创建嵌入的RosterDates和Shifts：

@Transactional
private RosterPeriod addRosterPeriod(RosterPeriod rosterPeriod) {
    LocalDate firstDate = rosterPeriod.getFirstDate();

    var shiftTypes = shiftTypeRepo.findAll();

    for (int weeknr = 0; weeknr < RosterPeriod.NUMBER_OF_WEEKS; weeknr++) {
        for (int weekdaynr = 0; weekdaynr < 7; weekdaynr++) {
            LocalDate rosterLocalDate = firstDate.plusDays((weeknr * 7) + weekdaynr);

            RosterDate rosterDate = new RosterDate();
            rosterDate.setDate(rosterLocalDate);
            rosterPeriod.addRosterDate(rosterDate);

            for (ShiftType shiftType : shiftTypes) {
                Shift shift = new Shift();
                shift.setShiftType(shiftType);
                rosterDate.addShift(shift);
            }
        }
    }
    return rosterPeriodRepo.save(rosterPeriod);
}

现在，错误如下：

Not-null property references a transient value - transient instance must be saved before current operation : domain.Shift.shiftType -> domain.ShiftType

这意味着它认为Shift.shiftType引用了ShiftType的一个 transient（也称为非持久化）示例。但是我刚刚用findAll（）从数据库中获取了这些示例！它不需要保存，应该由EntityManager管理。
我不明白你在说什么
我发现的建议是将Cascade.ALL添加到Shift.shiftType中，但这在概念上是错误的。例如，删除绝对不应该级联，但实际上什么都不应该级联。或者是并行流的问题，这在这种情况下不适用。
添加了完整的堆栈跟踪：

我认为@Johnnyutts在他们的评论中指出了这个问题：
您已将@Transactional添加到私有方法
这是不起作用的，因此您的代码运行时没有包含事务。所有事务只跨越单个仓库调用。因此，一旦您的ShiftType实体从其仓库返回，事务就会关闭，实体变为非托管。
将您的代码放入一个适当的事务中来解决这个问题。可以将其公开，并确保您使用的是正确的代理类型：Spring @Transaction method call by the method within the same class, does not work?
或者，您可以使用TransactionTemplate，我非常喜欢这种情况。
