Spring Data Rest - sort by nested property

Question

I have a database service using Spring Boot 1.5.1 and Spring Data Rest. I am storing my entities in a MySQL database, and accessing them over REST using Spring\'s PagingAndS

Answer 1

I debugged through that and it looks like the issue that Alan mentioned.

I found workaround that could help:

Create own controller, inject your repo and optionally projection factory (if you need projections). Implement get method to delegate call to your repository

 @RestController
 @RequestMapping("/people")
 public class PeopleController {

    @Autowired
    PersonRepository repository;

    //@Autowired
    //PagedResourcesAssembler resourceAssembler;

    @GetMapping("/by-address/{addressId}")
    public Page getByAddress(@PathVariable("addressId") Long addressId, Pageable page)  {

        // spring doesn't spoil your sort here ... 
        Page page = repository.findByAddress_Id(addressId, page)

        // optionally, apply projection
        //  to return DTO/specifically loaded Entity objects ...
        //  return type would be then PagedResources>
        // return resourceAssembler.toResource(page.map(...))

        return page;
    }

}

This works for me with 2.6.8.RELEASE; the issue seems to be in all versions.
