Pass groupBy parameter when using querydsl and spring-data exposed via a RestController

Question

I am exploring QueryDsl, and in particular @QuerydslPredicate used on RestControllers for binding rest params to Querydsl Predicates. An example endpoint is given below:

@GetMapping
public Page<UserViewDTO> findAll(@QuerydslPredicate(root = User.class) Predicate predicate, Pageable pageable) {

My request contains the following query params: ?username=user&page=0&size=10&sort=id,asc . Is it possible to somehow pass a groupBy parameter? I have looked at the documentation but could not find a way to do so. Adding it to the query params is simply being ignored.

Answer 1

Is it possible to somehow pass a groupBy parameter?

No, it is not possible to pass groupBy parameter by QuerydslPredicate
