具有子关联条件的CriteriaBuilder。冬眠

我有订单(ID,名称)和OneTomany to items(ID,名称):

我如何才能只获取这些订单,这些订单的名称为“香蕉”与标准构建者:

   @Override
    public Order orderQuery() {

        CriteriaBuilder cb = entityManager.getCriteriaBuilder();
        CriteriaQuery criteriaQuery = cb.createQuery(Order.class);
        Root root = criteriaQuery.from(Order.class);
        root.fetch("items", JoinType.INNER);
        CriteriaQuery d = criteriaQuery.select(root);

        criteriaQuery.where(cb.equal(root.get("item.name"), "banana"));
        return (Order)this.entityManager.createQuery(criteriaQuery).getSingleResult());

    }

我得到错误:

Unable to locate Attribute  with the the given name [item.name] on
