How to find all entities whose linked collection of entities contains at least one element from my list?

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。
