How to properly call PostgreSQL functions (stored procedures) within Spring/Hibernate/JPA?

Question

I\'m using Spring MVC 4, Hibernate and PostgreSQL 9.3 and have defined function (stored procedure) inside Postgres like this:

CREATE OR REPLACE FUNCTION your_procedure() RETURNS text AS $$
BEGIN
    RETURN 'Some text';
END;
$$ LANGUAGE plpgsql;

val query = session.createNativeQuery("SELECT your_procedure()")
query.list().map {
    println("NativeQuery: $it")
}
