关于java：Hibernate：为什么FetchType.LAZY-annotated集合属性急切加载？

Hibernate : Why FetchType.LAZY-annotated collection property eagerly loading?

我试图实现简单的一对多的关联。在使用调试模式检查项目对象之后，我发现已经加载了listbids。但是listbids属性用fetchtype.lazy注释。一些书籍和网页声称fetchtype.lazy是JPA提供者接受或拒绝的提示。但我想知道JPA提供者忽略fetchtype.lazy的条件是什么。提前谢谢。

private static void itemSeller(EntityManager em) {

Item item = em.find(Item.class, 1L);
System.out.println("hello");

}

编辑：我在语句System.out.println("hello")处加了断点。我检查了物品。如图： enter image description here 。
