Jpa criteria support in Hibernate ORM Panache

[hantsy]

JPA Criteria is very important for developers. Hope add Spring Data like Specification to build query Criteria and provide variants of existed methods , eg. findAll(Specification, Sort).

In addition to that, can we come up with something like JHipster's entity filtering mechanism?
It allows you to write things like age.lessThan=10 in your query parameters and get it converted to criteria queries.
Not a big feature but I would say it is a nice addition

There are ongoing discussion in this area in the following issue: #2303

If I'm not mistaken, the entity filtering is really how to expose arbitrary query restriction via your REST endpoint, correct @johnbanq? I think it's akin to the simplification of the REST enndpoint

[emmanuelbernard]

I agree with @loicmathieu I think the optional predicate will offer the same flexibility as specification and the same type safety once we plug the HQL resolver. I'd prefer we start with this approach before going on the heavyweight Specification approach Spring went to.

[hantsy]

@emmanuelbernard yes, the flexibility is important. Another concern is the Java type-safe query, which is provided by JPA Criteria API.
