Hibernate HQL Query : How to set a Collection as a named parameter of a Query?

Given the following HQL Query:

FROM
    Foo
WHERE
    Id = :id AND
    Bar IN (:barList)

I set :id using the Query object's setInteger() method.

I would like to set :barList using a List of objects, but looking at the Hibernate documentation and list of methods I cannot see an obvious choice of which to use. Any ideas?

hql hibernate java

Use Query.setParameterList(), Javadoc here.

There are four variants to pick from.

I'm not sure about HQL, but in JPA you just call the query's setParameter with the parameter and collection.

Query q = entityManager.createQuery("SELECT p FROM Peron p WHERE name IN (:names)");
q.setParameter("names", names);

where names is the collection of names you're searching for

Collection<String> names = new ArrayList<String();
names.add("Joe");
names.add("Jane");
names.add("Bob");
