如何从列表中查找所有链接的实体集合包含至少一个元素的所有实体？

Question

I want to find all entities Foo , whose Bar linked entities (via many-to-many relation) contains at least one element from my input Set .

@Override
public Set<Foo> findFoosHavingAtLeastOneBar(Set<Bar> bars) {
    QFoo foo = QFoo.foo;

    Predicate predicate = foo.bars. //I'm stuck here

}

When doing Ctrl + Space I can't find anything that could help me achieve this.

Is it possible to do that in a single Hibernate request?

您可以从输入栏中提取foo集，然后将所有foo集添加到另一个集中以删除重复项。
