我在实体图中为root元素调用函数merge（）。实体是级联的。在图中，有持久和瞬态元素。我插入了一个空的额外实体。实体：

@OneToMany(mappedBy="cnTermsGroup", cascade=CascadeType.ALL, orphanRemoval=true)
private List<CnTermsBudget> cnTermsBudgets = new ArrayList<>();
.....
}
在Hibernate日志中，我看到插入了两个实体：
Hibernate：插入CnTermsAmortization（cnTermsBudget_id，cnTermsCounted_id，id）值（？，？，？） Hibernate：插入CnTermsAmortization（cnTermsBudget_id，cnTermsCounted_id，id）值（？，？，？）
在控制器输出中，我看到其中一个在所有字段中都为空：
[CnTermsAmortization [id = 1，cnTermsCounted=entities.CnTermsCounted@47747fb9，cnTermsBudget = entity.CnTermsBudget @ 51684e4a]，CnTermsAmortization [id = 2，cnTermsCounted = null，cnTermsBudget = null]] < / p>
当我在图的根上调用merge（），其中所有实体都是Transient时，所有实体都正常工作 - 在输出中我有一个具有填充值的实体。我使用Hibernate版本5.1.1，JPA接口。 我错过了什么吗？
