Data module - how to create/initialize TypedQuery with CriteriaQuery

["Shultz, Dmitry" <Dm...@kaltire.com>]

Hi Guys,

I'm using Data module and trying to implement the PrimeFaces LazyDataModel using JPA c riteria API, like BaluC advised here:

https://stackoverflow.com/questions/17261124/get-rid-of-if-else-ladder-when-creating-jpa-criteria-query-based-on-sort-filter


My repository extends AbstractFullEntityRepository and I'm implementing method with signature:

public List<Message> findWithCriteria(int start, int pageSize, Map<String, SortMeta> sortBy, Map<String, FilterMeta> filters) {

CriteriaQuery<Message> criteriaQuery = criteriaBuilder.createQuery(Message.class);

... // add predicates and orders to the criteriaQuery

                entityManager().createQuery(criteriaQuery).setFirstResult(start).setMaxResults(pageSize);
}

The problem I'm facing is - I don't know how to get the entityManager from inside repository class. Or maybe I don't need to get it and there is some other way to feed to criteriaQuery into the  TypedQuery?

Thanks,
Dmitry
