我需要一个帮助者来了解是否已加载属性，以避免这种情况LazyInitializationException。可能吗？

@Entity
public class Parent {
    @OneToMany
    private List<Child> childList;
}

@Entity
public class Child {

}

"select distinct p from Parent p left join fetch p.childList";

// Answer goes here
// I want to avoid LazyInitializationException
SomeHelper.isLoaded(p.getChildList());
