Spring Data JPA - Get All Unique Values in Column

Question

Answer 1

Manish's comment should probably be bumped up to an answer (which i'll try to capture here since it ultimately solved my problem...although projections didn't seem to work with select distinct). The selected answer works in spring-data-jpa, but fails in spring-data-rest. One possible workaround for the spring-data-rest scenario is to create a separate @RestController for the select distinct results

@RestController
public class AddressRepoAdditionals {
     @Autowired
     private AddressRepository repo;

     @RequestMapping("/additional/address/distictCities")
     public List findDistinctCity() {
          return repo.findDistinctCity();
     }
 }

perhaps there's a similar but more elegant variation based on @RepositoryRestController
