I have a spring boot application in which I want to have the following SQL native query ordered by the chosen field:
Its a part of AbonamentRepo.kt file:
interface AbonamentRepo : JpaRepository<Abonament, Long> {
...
@Query("""
select abonament.id, abonament.data_rozpoczecia, abonament.data_zakonczenia, abonament.sektor, abonament.czy_zarchiwizowany, abonament.uwagi,
pojazd.nr_rejstracyjny_pojazdu, marka.nazwa as marka,model.nazwa as model, obywatel.imie, obywatel.nazwisko,
obywatel.pesel, abonament.pojazd_id, pojazd.obywatel_id, model.marka_id, pojazd.model_id, abonament.kiedy_utworzono, abonament.kiedy_zmodyfikowano from abonament
join pojazd
on abonament.pojazd_id = pojazd.id
join obywatel
on pojazd.obywatel_id = obywatel.id
join model
on pojazd.model_id = model.id
join marka
on model.marka_id = marka.id
""", nativeQuery = true)
@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator::class, property = "id")
@JsonIdentityReference(alwaysAsId = true)
fun findAllAbonamentInfo(): Iterable<AbonamentInfo>
AbonamentInfo.kt is the interface for the native query above:
interface AbonamentInfo {
val id: Long
var data_rozpoczecia: LocalDate
var data_zakonczenia: LocalDate
var sektor: String
var uwagi: String
var nr_rejstracyjny_pojazdu: String
var marka: String
var model:String
var imie: String
var nazwisko: String
var pesel: String
var obywatel_id : Long
var model_id : Long
var marka_id : Long
var pojazd_id : Long
var kiedy_utworzono : Date
var kiedy_zmodyfikowano : Date
var czy_zarchiwizowany: Boolean
}
In a file AbonamentService.kt I use java reflection to order AbonamentInfo.kt by a chosen field:
@Service("Abonament Service")
class AbonamentService {
@Autowired
lateinit var repo: AbonamentRepo
...
fun findAllAbonamentInfoOrderBy(pole:String ) {
val cls = AbonamentInfo::class.java
val field = cls.getField(pole)
val d = field.get(this) as Comparable<AbonamentInfo>
repo.findAllAbonamentInfo().sortedWith(compareBy { d })
}
This is AbonamentContrller.kt:
@RestController
@RequestMapping("abonament")
class AbonamentController {
@Autowired
private lateinit var service : AbonamentService
...
@GetMapping(
value = ["order/{pole}"],
produces = arrayOf(MediaType.APPLICATION_JSON_VALUE)
)
fun findAllAbonamentInfoOrderBy(@PathVariable(name = "pole")pole:String) = service.findAllAbonamentInfoOrderBy(pole)
And when i want to call a function findAllAbonamentInfoOrderBy for example like this:
http://localhost:8091/abonament/order/id
I get an error with the following stack trace:
2020-02-11 12:10:52.066 ERROR 7505 --- [nio-8091-exec-9] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.NoSuchFieldException: id] with root cause

What do I do wrong? do I use the reflection in the wrong way?
