Query annotations for EntityViews in EntityViewRepository does not work about blaze-persistence

[beikov]

Hey, it is not possible to use the @Query annotation along with entity views. You will have to write that query with JPA Criteria e.g.

@Transactional(readOnly = true)
public interface NodeViewRepository extends EntityViewRepository<NodeView, Long> {

    default NodeView findRoot() {
        return findOne( ( root, query, cb ) -> cb.equal( root.get("name"), cb.literal("root") ) );
    }

    NodeView findOne(Specification<Node> spec);
}

After digging a bit more through the issue it makes sense this wont work.
Maybe the idea for our own Query annotation seems a bit overkill but should be doable I think?
I'd like to hear your thoughts on what we would need and if that's even something interesting to have.

It would be interesting, but that depends on #252 which is not so easy to implement. If jakartaee/persistence#29 were already available, I could just reuse the parser of the JPA provider instead, but having to implement a custom parser requires a lot of work and integration with the parsers of the JPA providers is probably even more work.
